Shop Alpine Car Audio Alpine Type R Subwoofers

These incredible subwoofers from Alpine have withstood the test of time and proven themselves to be one of the top subwoofer choices for car audio enthusiasts. The Type R subwoofers are designed and engineered for big bass, as well as a durable sub that will last for many years to come. These woofers use a pulp cone that is reinforced with Kelvar for an incredibly durable and rigid structure. The ribbed multi-roll santoprene surround is designed for excellent response, while assisting in smoother cone movement and excursion. The subwoofer will stay cool under extended hard playing with the unique thermal management system that Alpine designed into the Type R Subwoofer. The tinsel leads are hidden and woven into the dual Nomex spiders for a strong and unbreakable connection. For those looking for an industry standard subwoofer with break-taking bass, consider the Alpine Type-R subwoofer.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Type-R (Alpine)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
12"
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
1500 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
500 watts
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Dual
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
4 ohms
Voice Coil Diameter
Diameter of voice coil, usually measured in inches.
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
23 - 500 Hz
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
85 dB
Xmax (millimeters)
Typically measured in millimeters, the Xmax value is the measure of a speaker cone's maximum excursion in one direction while maintaining a linear behavior.
18.2 mm
Subwoofer Design
This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Round / Circle
Main Cone Color
This is the color of the speaker's or subwoofer's cone.
Dark Gray
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Kevlar Fiber
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Santoprene Rubber
Magnet Structure
Defines the overall structure of the subwoofers magnet.
Subwoofer Grille
Most subwoofers are able to accommodate a universal grille; however, some subs include a grille and others have a specific, optional grille available for purchase separately. If "yes", then the subwoofer includes a grille. If "optional (sold separately)" the matching grille will need to be purchased in addition to the sub.
Optional (Accessory required and sold separately)
Re-Cone Kit Available
Some higher end subwoofers have replaceable cone assemblies. In case of a blown woofer, a recone kit allows for a simple replacement, as opposed to purchasing an entire new subwoofer.
No

Recommended Enclosure Specifications

Recommended Enclosure Type
This is the recommended type of enclosure that the subwoofer should be installed into. Some subwoofers are specially designed for particular enclosures.

Sealed: These enclosures completely enclose the air inside the box. These boxes produce a tight bass.

Ported/Vented: These enclosures have a slot of air to escape from the box. The result is a sound that has more "boom".

Bandpass: These are a combination of both sealed and ported enclosures. They can be very efficient, but require tuning for the best response.

Ported / Vented
Sealed
Minimum Sealed Box Volume
This value indicates the minimum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
0.57 cubic feet
Optimum Sealed Box Volume
This value indicates the ideal sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
Maximum Sealed Box Volume
This value indicates the maximum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.0 cubic feet
Minimum Ported Box Volume
This value indicates the minimum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
0.75 cubic feet
Optimum Ported Box Volume
This value indicates the ideal ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
Maximum Ported Box Volume
This value indicates the maximum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
2.0 cubic feet
Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
7-3/4"
Cutout Diameter
The actual diameter of the hole you will need to cut out if you are creating a new mounting location for this speaker, or if you are mounting a subwoofer in a box.
11"
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

No

Electromechanical Parameters

Free-Air Resonance (Fs)
The free-air resonance frequency of the subwoofer, measured in Hz. At this frequency the weight of the moving parts is perfectly balanced with the subwoofers suspension system.
Equivalent Compliance (Vas)
This is the amount of air that has the same stiffness as the subwoofers suspension. The greater the rating, the lower the stiffness and larger recommended enclosure. It is measured in Liters.
Total Speaker Q Value (Qts)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including all dimensionless losses. Essentially, a high Qts value (closer to 1.0) means the subwoofer is great for sealed enclosures and a low Qts value (closer to 0) means the woofer is great in vented enclosures. A Qts of around 0.45 means the woofer will work decently in either enclosure type.
Electrical Q Value (Qes)
The subwoofers relative damping (Q) at the resonance frequency (Fs), including electrical losses. Also called the mechanical damping of the subwoofer. The unitless measurement usually varies from 0.5 10.
Electrical Resistance of Voice Coil (Re)
Amount of DC resistance of the subwoofer when measured with an ohm meter. Typically, this will read less than the impedance rating of the subwoofer.
Mechanical Q Value (Qms)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including mechanical losses. Also called the mechanical damping of the subwoofer. This unitless measurement usually varies from 0.5 10.
Efficiency Bandwidth Product (EBP)
This number represents the trade off between having an efficient woofer and one with a wide bandwidth. To calculate this number, take the Fs and divide it by the Qes. If the number is below 50, the woofer is designed for a sealed enclosure only. If it's between 50-100 it can be used in either. Lastly, if it's greater than 100 it's designed for vented enclosures.

May 21, 2010

I bought this sub to save some space in my trunk. I have been a two 12s guy for as long as I can remember and was convinced that one sub just could not cut it. I was so wrong. This sub with a pdx 1.600 and a 1.8 ported box kills it. There may be better speakers out there but for the price there is no comparison. Price is all I can say. On and off car audio guy for ten years. Anyway I almost wanna pick up another one just in case my GF ever wants a sub but I'm too cheap for that. Quality bargain hunters search no further.

Picked up 2 of these alpine 1242d 12's and put them in a ported box hooked up to a mrp-m2000 amp and they can handle the amp on some serious shake work. the ring on the sub flexes great. I had to turn the amp down for sure as not to blow the subs but have them running now @ 4 ohm parallel and they love it. i for sure am going to pick up another set and run them @ 2 ohm b/c they can take it all easily. def competition grade for the folk with a low budget.

Type R

December 28, 2010

I bought this sub about 6 months ago. At first, I had it running on the stock amp (about 60w rms) in my Cobalt, enclosed in a 1.25 ft^3 sealed box. As one could imagine, it just wasn't loud enough, so I bought a ported box (also from this site) and added a Fosgate amp. I am a guy who enjoys his low notes, and the Type R delivers great low end response! Overall this is a quality product (as is everything Alpine has made) and Sonic is the best site to buy from. I would highly recommend this sub! Combine it with a good 500w amp in a ported box, and you will NOT be sorry.

They Punch Kittens

August 30, 2010

I bought a pair of these to go into just over a 2 Cu. Ft. sealed enclosure (MDF sides and back, glass front, separate chambers) They hit very well for being in a sealed enclosure. They are a bit heavy at 26 Lbs. I'm pushing them with a pair of PDX 1.600's with LPF's set to 100 Hz. Even with the gain set to the max, which I don't suggest unless you are using an inline bass remote, I don't get a hint of distortion even when the volume is to a point of being physically painful.

Huge Improvement of Product

June 9, 2006

I had bought 2 type r's back on 2002 and I was very disappointed with their performance. Now that they have been redesigned and the surrounds made to mimic the type x with 500 watts rms rather than 300 rms you get an awsome bang for your buck. Also with the sealed 12" boxes available from sonic you can run more power to them and not worry about blowing this sub. I plan to run it at 2 ohms with 1000 watts rms daily. I definately suggest running sealed but that's my personal preference on any sub. I've seen several with mrd1000's and they thump.

I have 2 12" dual 4 ohm in my truck in a custom box I made, internally braces and sealed all the way around. Even though this box was made to specs and solid as a rock I wish they could go a little deeper. But for what I payed these are great and they still hit deep enough to shake windows when I pull up somewhere. Overall this woofer is very versatile and sound good when in the right box.

Very Good Quality

January 6, 2010

I honestly wouldn't put one of these in my car again but i will have to admit, this sub is really nice. I just don't like the way it looks in my trunk lol. But if you want a damn nice sub that can take abuse and can hit lows, this is for you. This sub is durable as can be. No tinsel leads to worry about because they are under the spider and the excursion is ridiculous. The SQ is quite good too. Definitely needs to be ported i think, but it depends on what you like boomy or flat response. I would recommend this sub if you want a really good quality sub that will last a long time.

This subwoofer slams and has great control. If your box is properly designed you will be none the happier. Lacks on SQ but for now I\'m not in the market for a more expensive subwoofer. It works with all types of music. It is a very good subwoofer for the price.

December 11, 2008

I have one alpine 12, with a jl 500/1 powering it, and this sub is louder than most two twelve systems. i built my own box according to specifications and wow.

my rear view mirror is about to fall off.

i also have 4 alpine type s speakers which make the highs so clear even with the loud sub in the back.

very very clean bass, very low bass as well...

i highly recommend. very highly, after the speakers and the sub both being amazing, way beyond my expectations, i would now have to call myself an alpine man.

way more than I expected, very impressed

November 16, 2007

Just installed mine tonight and I had to go riding a couple blocks. I am hooked on alpine after hearing my two in a 6cu ft box tuned to 34hz in the trunk of my 1993 cadillac devile (which has a one inch firewall between the cabin and the trunk) powered by my soundstorm cr4000.1 at 1 ohm. The bass is insane at low volumes with the bass setting on my head unit at the very minimum. These subs do way more than I expected them to do. The best part is that they require so little power to do it my amp might as well be on vacation. I had to reduce the level of bass boost on my amp. Thanks /////ALPINE and Sonic

Pros: alpine trusted brand, solid bass, high quality sound, and reasonably priced, extremely durable

Cons: it wasn' t free lol, no weaknesses, do not under power, can't handle power, buy a real amp

August 10, 2010

This is a great sub for the price, a lot of bang for your buck. I bought this as well as a Boston spg555 and although the spg555 dominates this sub it still packs quite a punch and is well worth the price. If you're an audiophile i wouldn't recommend this sub though, this is a heavy hitting sub and although better then some subs I've heard, not audiophile quality, would recommend something like the spg555 for an audiophile. Still a great sub though.

Hits HARD

July 26, 2010

This sub is crazy. people think (me once included) that if it wasnt a kicker or something equally as hyped, it wouldnt hit hard. I read reviews and actually just got lucky with these. My sub (audiobahn) blew out due to installers mess up and so they gave me this one for free. I thought there was gonna be no way it would be better than my old one which hit pretty hard... It blew my old one out of the water!! I loved it so much that a week later i bought another one with a bigger amp and box. I loved it. It is easy to underpower these things so unfortunately u need 2 buy a decent sized amp that will cost u a little bit but its worth it. Do yourself a favor and save money (contradictory to what i just said but compared to a kicker u will save) and get these. You wont be disappointed... btw my amp is a alpine 1000 watt rms amp. (these give out 500 rms each but can go higher. my amp mite b underpowering them)

very affordable entry level sub

June 9, 2010

This sub is very affordable and doesnt require that much power. I had 2 of these hooked up to a hifonics bxi1200, that was a pretty good match. I originally had it in a prefab vented box, didnt sound to good so i made a sealed box with the exact specifications in the owners manual. Very clear subwoofer i tried them free spaced and they sounded a little better in my tacoma i would buy again.

They slam hard. My rear view mirror fell off from them, and I set off a few car alarms too. They hit a bunch of the low notes that a typical 12" cant hit. I have them hooked up to a jl a1800 monoblock amp, and they sound amazing together. my only problem is that it lacks on the higher notes. I may need to make a bigger box, or power my subs at 2 ohms instead of 4. Overall, they're the best

Good Speaker

November 4, 2009

If you need a speaker that will sound good in a small box then buy the TYPE R. I have a very small custom box that I've build for my trunk, while doing the research, Alpine speaker said it need minimum of 0.57 cubic feet for enclosed box, and that was perfect for me.
The sound it produced is more than I've expected. Im happy with it.

September 23, 2009

I bought two of these 12 inch type r's today man do they hit. I did have 2 10" boston acoustic g2's so my 8 gauge wiring kit isnt enough but I will be buying a 4 gauge tomorrow or tonight so these subs will pound, hard. I can't wait my trunk already rattles to all h*** and people love riding in my Plymouth Breeze (I know) because of the clean, hard hitting bass that gives everyone a back massage because of the vibration. The 10" boston acoustics were also awesome, but these are better. I would definitely recommend either of these brands.
Stay loud!

The hardest part to any system is to find the right amount of power, for the alpine SWR 1242 i found the best result came from the Kenwood KAC-9104D. it preforms great, if you are looking for a system with some heavy kick but just one subwoofer. i look forward to making a full transition to an alpine system within the next few months.
i gave it a 5 for the Durability features and ease of use because well, it has not let me down yet, and probably will not anytime soon.

I ALMOST bought them again, but then Alpine made the Type-X! Holy cow! It's the type-r's on steroids! If you don't want to pay the extra $120 buks, go with the Type-r's and you wont have any regrets!

Alpine's Type-R is a great

January 30, 2008

A friend of mine ran a pair of these on a VA Audio VAAM 1600 in his S10 Blazer for about a year or so. I took them from him and put them in the trunk of my Volvo on the same amp for a few months, and then wound up selling them to another friend of mine to run on, once again, the same amp in his Honda Passport. All I can really say about these is that they are great for what we've spent on them. We've been running them at only 400w RMS per sub (way underpowered, you can hook one of these up to the amp by itself and the full 800w RMS won't distort it by all that much.) When my friend in the Honda upgraded from his Sony Xplod 12" subs he'd had about a year he was amazed at how much louder and cleaner his bass was. Even in the sealed trunk of my Volvo, I would set off car alarms and shake my rear view mirror to the point that I could hardly use it.

Great subs. If you're looking to spend less than $500 for two subs, an amp, and a box, these are a great choice to start off your system.

Note: Even in 3 cars, on 3 amps, being wired countless times in more than 4 different boxes, I've yet to notice ANY drop in sound quality or loudness. They still haven't even began to wear out, which is impressive for any stereo equipment over 2 years old. We even dropped one and cracked the back casing, and it didn't effect anything more than cosmetic damage on the sub. Durability, and therefore resale value when you're ready to move up later on, definitely show here.

This subwoofer is beyond crazy..Alpine has created a monster sub. I hooked this up to a directed D2400 amp, and you have no idea..this speaker weights a lot because of the enormous magnet that supports the sub.. I've owned over 10 different brands of speakers in my day and i tell you, i will ever own another sub besides this sub..in the future i will probably buy a 3rd type r, but trust me..buy this speaker, plus sonicelectronix is one of the cheapest places on net..dont buy this product from any stores because they range from over 200 dollars..buy this product here from sonicelectronix and you wont regret it..

Great sound when in the proper enclosure

July 13, 2007

This subwoofer sounds real good when in a proper enclosure, however, this subwoofer does not do very well in a sealed enclosure, so i recomend getting a properly ported enclosure, and it will sound much better & louder then with a sealed enclosure.

This subwoofer has a excellent sound quality for a subwoofer in its price range. Just a single Alpine Type R subwoofer, in a properly tuned ported enclosure will make your windshield wipers bounce off your window.

I Purchased this sub about three months ago and first put it into a 1.0 cubic foot box. I kept it in that box for a while and realized that it needed to be in a larger box. Amazing sub. make sure you put it into a larger box than recommended. This sub will pound harder than anybody at my school.

January 11, 2007

This is a great subwoofer. it hits very hard off little power. Although the cone is quite fragile, I enjoy it very much. I also like the little speaker wire plugs that it comes with,(you really have to tear the box apart to find them), but its a nice feature.

Alpine Type R 12

December 22, 2006

I have recently ordered this sub because i have previously owned one and wanted to add to my bass by having two. The price is excellent and the shiopping is quick. The sub is great quality and precise. Buy this sub and order it from these guys here at sonic electronics.

THE BEST BANG FOR THE DOLLAR SUB, yes ik these subs are used by everyone and i get sick of looking at them but let me tell you there a reason why everone has these. If you purchase this subwoofer please do not purchase some crappy prefabbed ported box. BUILD A BOX, i recomend 2.5 cubic ft after displace tuned 32-34hz.

My friends has 3 of these in his truck. They boom like their is no tommorrow. He has entered and won one competition. So that shows that the subs are defitanely worth it. These subs are very power hungry so get an amp with alot of power for them. They will take all they can get.

I have one type R hooked up to my alpine MRP-M650 and it hits hard. The sound quality is great. These subs can handle lots of power. They hit a wide variety of bass. From rap-rock it all sounds good. You cant go wrong with buying an alpine so i would recommned these to anybody.

September 15, 2006

I have two dual 4 ohm alpine Type R's hooked up to a Orion 600d amp which puts out about 600rms at 1 ohm which is what i have the subs running at. These subs are extremely loud and clean they are everything your are look for in subs. I have only had them for a week and already i have been pulled over and set off a couple car alarms:). i would suggest these subs to anyone unless u can afford the type x's

August 18, 2006

I have one of these pushed by a kenwood 1100 watt monoblock amp and it is in a custom box that i built just to the numbers alpine recomends and this thing absolutely pounds. It hurts my ears to listen to for more than a few minutes. It vibrates everything in my car. I would strongly recommend this sub to anyone who is looking for a lot of bass....it will get the job done and the price isnt even that much. I can have it one and people can hear it 2-3 blocks away. its insane

I used to own this sub but have since sold it to a good friend of mine. I only had it in for 2 weeks so I wont comment on my experience as much as my friend's set up, he only has ONE and I can hear him coming in his stang a block away! If you buy this sub you should seriously consider dynamat or something like it cause it WILL make your trunk sound like its about to fall off. Its a great sub and I would recommend it to anyone!

I have have 2 dual 4 ohm alpines on a bx1800d Hifonics 1800 watt monoblock....these subs (even though rated at 500 rms ea,so the pair 1000watt rms) handle all the power i can feed to them they have an awsome cooling design and they are very clean acurate bass pounding monsters i have them in a box alpine suggested i build for 32 HZ and it plays all notes very well id say the cone of my woofer flexes every bit of 2 to 2.5 in. on certain bass notes...if you really wanna know about these subs or any before you buy them look at the videos of these woofers on realmofexcursion.com and click on videos ...your brand names are down the left side of your page click on alpine and go to the type r model...begin watching .... love these wooofers:) another thing.. i just got back from a sound competition in liberal KS and got a second place trophy a 149.7DB at 50Hz with 2 12's

These subs are probably some of the loudest and cleanest subs ive heard in a while... These subs will put out the given power and will take it with no problems at all. If you need some loud, clean subs and are not looking to spend too much money the alpine Type "R" is definitely the way to go..HAPPY BUMPIN!!

I own 1 of these subs and it sounded good for about 2 months, I had it hooked up to a power acoustik amp with 880w continuous, and the sucker fried. I was rolling through the block and the sub quit, I opened up my trunk to my cadillac and smoke came rollin out. Good sub, but from a brand like Alpine, I expected better.

Best sub for the price.

January 17, 2011

I have been into car audio for 20 years. I have owned many types of subs(all name brands)all have been in sealed boxes(I like the sound)so that is what my review is on.All of my car's have been about sound quality not about db.I have 2 of these subs each in a 1.2 cf box,In a 1972 Cutlass convertible with a 1000 watt amp pushing them @ 1ohm. These subs are LOUD and sound great!(with the top down and even better with it up). I think these are the best sub for the price and will out play subs that cost much more. i have had the subs running for a year and they get better every day.

Alpine type r great sound for great price

December 20, 2010

got this a few months ago for a good price. lows on this subs is clear and deep. running it with alpine cda117 head unit and alpine mrp-m500 mono amp at a stable 2ohms. the thing about this sub is you can't just go out and buy a cheap prefab box, you need to get a box built to its specs to get the full use out of the sub otherwise your system will sound like crap and you can even ruin the sub. spent $250 just to have the box built to its specs. overall great sound for great price.

This sub will take every bit of it with no fear. but i only have the amp at half way and it is still heard from 3 to 4 blocks away from my house. I got my first ticket for noise pollution a couple months back. The officer testified that he felt coming from well over a hundred feet. The bass quality is superb, can't wait to get another one!!!!!!!!!!!!!!!

Much Better Clarity

August 26, 2010

Had a store credit, added some bucks to it and got this ALPINE SWR-1242D with the idea of swapping it out with the Hifonics BRUTUS I already had in a ported 1.75cf enclosure.

Part of what made the decision was because Sonic listed the cutout diameter as 11". * * * IT IS NOT... IT IS 10+7/8". * * *

That was a minor annoyance as I had to graft a 2nd baffle piece on top of the enclosure over the original hole (the original whole was just a hair too big, the screws would have ripped-out of inside of the circle in the wood for sure).

Anyhoo.... ON TO THE GOOD STUFF....

The clarity of the reproduction of the bass tones with this driver I noticed definite improvement over the Hifonics BRUTUS. And I'd have to say there's even a little more of a punchy crispness to those certain kinds of kick-drum type hits too.

Theirs no comparison when it comes to the stiffness of the cone/dust cover on top. The BRUTUS could be flexed easily with fingers.

I'm only running this with a HITRON HA-1000.1 @ 2 Ohm and it gets loud and sounds damn good. However I get the feeling that with a more powerful amp this thing could be pushed even further. I dare not push it too hard with the HITRON for fear of underpowering it and burning the voice coils. That being said the SPL is already ridiculous and gives respectable migraines (HeHe).

The box comes with banana-plug jumpers for the voice coils and the voice coil connections are all right together. Nice and easy. It also comes with a rubber push-in ring which covers over the screws for a clean look to the install.

The documentation pamphlet shows a ton of different ways to configure connections to one or multiple amps connected to one or multiple woofers showing the Ohm load presented for each configuration. I was always curious about 3 woofers configs so that was kinda neat to read.

I love watching my watter bottle dance around in the cup-holder. =)

One heck of a sub!

July 8, 2010

I got one last week and it hits so low in my 1.4 cubic foot sealed box. It should be in a smaller box but this one was already built. The banana connectors are very handy but note that it does not come with any mounting hardware. It comes with recommended box dimensions also. This one 12" sub rumbles the hell out of my car and the best part is that it goes louder! I bought this sub based on reviews on this website and I don't regret my purchase one bit even though it cost me $370 Australian. I would recommend this subwoofer to anyone!

This subwoofer is amazing, I'm running one to an alpine mrp-m500 at 2-ohms with roughly 500 watts going to it and it hits sooo HARD. It blows away my friends two 10" alpine type S's. This subwoofer will put out the best quality of bass that you have ever heard. One important thing tho is to let break in good before you bump it too hard. After she breaks in it is the best sub EVER. please buy this subwoofer if you are looking for extremely goood bass at not a bad price, so worth it!

But let me tell you. For 1 12" it take all the power all day long with no problem. And gets very loud. Well worth the money and i WILL be buying another one from sonic!

i LOVE this sub! It's matted with the Alpine MRP-M500 for the power and this combo cannot be beat! I am heard from BLOCKS away, and mind you it's only ONE type-r sub. I was gonna put two but it's definitely loud with one. It's super easy to install and Sonic helped me out to pick out the right sub and amp combo to make sure i was running the same ohms.

Perfect subs

April 30, 2008

I've checked over the web for months before buying new subs for my accent 99 hatchback.

The alpine type R were highly suggested everywhere. You know when a product is great when nobody on the web diss it. That's the case with the 1242d or 1212d.

So I hooked two into 1.3 separated chamber powered by an hifonics 1606d. At first, i tought my cheap pionners subs were louder, but those were cleaner.
Then, me and one of my friend build a 4.2 net ft/cu enclosure tune to 32hz and now.... that's insane. Everybody want to get in my car to hear them. My whole car is dynamated, but the subs make everything shake anyway. The Sound pressure is inbelievable. Don't know how i hit, but it's over 140 that's for sure. I can't stand in the car more than few secs at a time.

So, buy those, get yourself a big ported box, get youself ear plug and listen to those subs. Even with -32 db attenuation, the bass is jaw dropping loud and hard hitting. Song like "i wanna love you" by akon are ridiculous

Best Bang For Buck

April 23, 2008

Awesome sub! I had one of these in a ported box and it killed most other peoples systems. Even alot of people who spend more on theirs agreed that mine was louder.

Alotta Bang For The Buck

February 21, 2008

I just ordered two 12" alpine type r's and hooked them up to a 1000 watt RMS amp at 1 ohm. They have been in use for just a little over a month and they definitely pound. Though the subs hit very hard, the bass isn't as deep as I would like. I only listen to rap and if you're looking for subs with very deep bass, go for a sub with a larger magnet or even 15's. But with the price from Sonic, I guess I can't really complain. All in all, if you want a good choice in subs and want to stay at a reasonable price, go with the Type R.

Alpine is famous for premium products. The type r line continues this tradition. The alpine sub hits amazingly hard and is amazingly low priced on sonic electronix. WHen matched with an amplifier from alpine however, be sure to test for true rms wattage as the alpine amplifiers tend to put out more power than advertised. IT may say it pushes 600w rms @ 2 ohms, but it can actually be pushing around 700.

Bottom line, this is a wonderful product, and I'm am going to get another one. This will be my first purchase from here, my first time owning a type r, but not the first time hearing one.

Best sub for price HANDS DOWN!

October 12, 2007

I have 2 of these in a sealed box and the have the cleanest bass that I have heard. In a ported box, they will rock the block for sure. I am running a 600w RMS diamond audio amp at 1 ohm, and 2 of these wired to 1 ohm and they produce very clean and accurate bass. I will upgrade my amp and get a ported box soon from sonic!

September 27, 2007

Yo this sub is on point. I got just one Type R hooked up to a 6002 Rockford Fosgate and I couldn't beleive how deep and powerful the bass was. the Type R is in an sealed box and it sounds way to good to be true+ and for the price you just can't beat it.

I waws suprised at the great SQ and SPL of this sub, even ported it still produces clean accurate bass. I have three so far and im gonna buy one more. Bought two from an audio and my third from Sonic and it was half off Sonic has the lowest prices around, trust me buy from Sonic they have the lowest prices.

IT THUMPS SOOOO HARD!

July 13, 2007

i have a 4 door truck so i don't have room for a big box. i bought two of these and put them into a box that is only 30" wide. i'm running them off of a boston acoustik 2000 watt amp. this is my ninth pair of subs and i wouldn't trade them for anything. they hit the hardest, go the deepest, and vibrate my car like no other sub i've owned. i gave up kicker cvr, mtx, JL, type E, and another pair of mtx's, but i will stick with these! i will challenge any other 12's at this price!

July 12, 2007

even off 350rms, this subs hits hard! probably not for those who are used to running 1kw-2kw systems, but just one of these will give any beginner something to bump with! no complaints, quite possible the best sub for the money!

LOUD and CRISP!

December 22, 2006

Well, it bought two of these 12's to connect to my BOSS amp (very fine product BTW), and these thangs HIT! I bought these to replace my older Infinity References and it was the smartest move. Not only do they hit harder, but they take as much juice as you can throw at them. If you get two (which is a bargain at this price; almost the price of one from other places) you can wire them for either a 1-ohm or 4-ohm load. At 1-ohm they are the loudest subs on my block. I've never seen a lower price for these kevlar reinforced 500-RMS monsters.

best bang for the buck period

December 22, 2006

I have owned many different brands of subwoofers from rockford fosgate to sony. I have to say this speaker out performs any sub in its price range hands down in both sound quality and spl. I own two of these teamed up with a hifonics BXI2006D@ 1 ohm 2000 rms, that 1000 over there rated rms and the take it like a champ. I have them in 5 cubic ft enclosure tuned to 32 hrz the bass is tight, accurate and LOUD to say the least. If you are on a budget and want kicker,jl,rockford bass buy these along with a hifonics amp and you will have no regret.

Great Subs

December 18, 2006

These are some of the best subs on the market. They sound clean and hit hard, but becareful and use a quality amp. If not you will get major distortion and will blow them. They are power hungry subs so for the best sound don't skimp on the amp. Go BIG with the amp and you will be very pleased.

Very clean and hard hitting

July 6, 2006

I bought a pair of these subs and put them in a sealed enclosure hooked up to a Hifonics 1206Bxi running at 1 ohm impedance. These subs hit pretty hard but nothing to write home about, I think that the amp is drawing more power than my Tacoma can handle and therefore not really pushing these subs to there limit. I plan on getting a capacitor and then see what these subs can really do.

I have two of these hooked up to a Rockford Fosgate RF 7 amp. I have them running at 4Ohms so I'm getting at least a total of 1000 watts from my amp. They pound hard and with accuracy. The only subs I've had or heard that were better are JL's. I also have a Kicker L7 05 in a Kicker(Godzilla) box....the Alpine's don't get as much SPL as my L7, but I think the reason why is the box. The box I have them in was custom made for JL W6's version 1's...which had an RMS of 300 watts each. So once I get a new box, I hope I'll get just as much SPL as the Kicker with as much SQL as JL's!

best subs ever

February 17, 2006

So im 17 years old,and i wanted 2 have a thumping system. i went to best buy and heard these. WOW!!
i just stood there and watched as they played. The song playing was Lean wit it rock wit it by:DFB. they were playing on an 800 watt kenwood class d amp. so the next day i bought them. but i decided to go with a bigger amp. so i searched around and found a PYLE 2000 watt mono amp. that pushes out 700rms @4ohms and 1000 watts @2 ohms. so it was the best match ever.i put them in a audio innovations vented box from b*** b**. and hooked it up 3 weeks ago. OH MY GOD!!! it shakes everything in my car. Oh by the way i hit 152Db at a local competition. SO in short BUY THESE!!!!!!!!!!!!!!!

Peace out- thumpin kid

These subs are simply amazing!! My friend has two of these, we hooked one up to my profile amp (500W RMS at 2 ohm) and turned the volume up to 22 out of 35 and my ears stared to hurt. I highly recommend these subs over almost any thing, including the MTX 8500s. Do it right the first time, buy alpine and you will not be disappointed.

Alpine, as a fan, go for it

August 17, 2005

I have 2x in my 01 galant and the BANG is on.

Big fan of SQ and Alpine surely delivers on what the promise, GOOD SQ and good value.

If you like BOOM BOOM go for Alpine woofers and Alpine amps, they deliver the power thees subs need.

Big fan of Alpine, and I say, looking for subs and good price, Alpine is the deal.

Just make sure you have the amp to push this sub, or else you will get crapy sound.

Me and two other friends have pairs of these. All of us have different amps and no matter how many watts or what kind of amp you hook them up to you get great quality and volume. The only thing I didn't like was that the cut out diameter isn't 11in. Kinda messed up my custom box I made but other than that these subs are amazing! Would recommend to anyone!

Awesome Subs

September 11, 2010

Bought two of these to go in my 01 Honda Accord Coupe. Have them in an ported Obcon box, google it, and an Alpine Mrp M1000 amp currently delivering the recommended 500 Watts RMS. They pound, point, blank, period. I'm not really a bass head either, the sound quality while pounding is superb, much more than I expected. I have had all types of subs and these are definitely the best ones I've had in terms of sound quality.

March 8, 2009

The sub is awesome, Ive owned 2 of these in my car for over 3 years now and they\'re still hitting like when they were new. The quality is the best, come on, its alpine. Ive bumped these for hours straight, and they still perform very well. These are good subs because they have really good bass and still has very good sound quality, they will hit the lows and highs like no other subs for the price and even more. I have 2 of these with a pdx1000 amp to each sub and sound very good. I recommend these subs to everyone i talk to, cant go wrong.
