New and Improved Alpine Type-R:

This fourth-generation Type-R subwoofer features the cleanest sound with the most efficient force control. With updated assembly, this subwoofer is able to withstand higher temperatures more efficiently without distortion. This new structure greatly improves installation options by allowing a shallower mounting depth. Delivering the best bass output, the Alpine SWR-1223D has been redesigned to enhance audio playback and become your ideal sound system. Type-R's new depth design offers a 20% reduction while adding the new and improved magnet structure. With this updated double-stacked strontium magnet, this product gains over 20% more motor force to provide a louder, cleaner bass. The optimized CRC machined motor creates an even magnetic field to provide the user with less distortion and overall improves the subwoofers power handling. This subwoofer features a High-Amplitude Multi Roll (HAMR) to provide excellent excursion with overall better output. Having a new and improved airflow management system controlling the temperature of the voice coils, the air is redirected across the heatsink to avoid overheating. With heavy playing time, this heatsink feature minimizes the amount of compression to reduce any heat damage to the voice coils giving you a long-lasting 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.
1800 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.
600 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.
2 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 - 400 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.
20 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.
0.65 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.
1.25 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.
1.0 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.
6-3/8"
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.
10-13/16"
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.

March 1, 2011

These things have some power. No doubt the best I've heard. The neighbors get so mad, even people driving next to me. I have mine wired at 2 ohms hooked to a power acoustik 3000 watt amp. I'm sure the amp isn't pushing 3000 watts all the time, but the subs still get insane power, and have great power handling.

hits hard and is durable

February 21, 2012

I have two in a ported box running at 400watts each. Wired to 2 ohms. They slam. They don't have much distortion. I got them 6 months ago and held up great. I got an alpine 15 type-r and need to install it. All I have is Alpine in my car. Also 4 spr-60c component speakers from alpine. I'm running them at 50 watts each and they're great. I'm going to run them at 100 watts each soon since they're rated 110 rms. Anyway alpine is awesome and the way to go. With just those 2 swr 1223d's I've gotten pulled over for shaking a cop's windows while I was at a red light and he was over in a parkinglot about a block away.

June 7, 2011

After about 6 months of deciding... i buckled and got the Alpine Type R. Always heard good things about them and decided to get a set. FIrst off these things are monsters. They already sound better then my P2's and hit harder and deeper. Very pleased with my purchase and can't wait to hear them when they are broken in.

Alpine type R vs Kicker L7

September 1, 2011

I bet a lot of you wonder which system would hit harder.. i had 2 kicker L7's 12" a couple monthes back, they hit im not gonna lie. but when i got 2 type r's recently, i am absolutely amazed of how hard they hit. im not over exagerrating but when i drive my vision gets blury, my throat starts to choke in a way, and ribcage rattles. So in my opinion type R would be my first choice no matter what. If you get a huge box and a powerful amp for these than i guarantee it can out do most 12 " subwoofers.

Great sub

July 21, 2011

This subwoofer definetly gets the job done. It sounds great and has a solid punch. I have one of these in a smaller sealed box, I think its 1 cubic feet, but one should get a larger box in it. Only problem is that it does tend to rattle when it gets to high volumes, but only when a song has booming bass so it doesn't happen that often, could be the box. I added this in my 08 jeep cherokee and its a good combo with my recently added speakers. Here's what I got; sub amp- kenwood kac-7204 (bridge the two channels) head unit- kenwood excelon, front seat- boston acoustics pro60SE, back seat-boston acoustics sc65. Sub sounds great with the replaced speakers, but a four channel amp is still on my list. Overall the 1223d wont dissapoint you, and it was a nice upgrade from my 2 jl audios 120v2-4. With just one type-r it sounds better and louder. However, there are still better subs out there.

November 11, 2010

I have one Type R in my 1997 Cadillac Deville in a slot box hooked to a 800 watt Power Acoustic CPT2-1500 amp. With the amp bridged and running at 2ohm's it hits extremely hard and the sound quality is awesome. However it dosen't take long for the amp heats up and shuts down. I plan to upgrade to a better amp and it should be fine. This one sub hits harder than the two 15" Audiobahn's in my Bronco.

January 10, 2012

I have had 1 in my truck for 2 weeks now, after my Kicker Comp VR finally blew. No dig on Kicker, cause that bad boy lasted me a hellish 8 years. This sub just gets better and better! I'm slowly moving the settings up, just out of my own choice, but man, WOW. I cannot wait to really pound on this thing! I have it in a Supercab F150, in a 1.27 cu.in. ported box. It's really impressive what 1 sub can sound like!

The redesign has been great for this sub... making the mounting depth less has not reduced the quality of sound you get out of it!

It sounds great and pounds good under the backseat of my silverado... which is a hard place to fit any 12" sub, let alone 2 that sound as good as this Alpine

great subs

March 22, 2013

I have two older Alpine SWRs. My older version are 600 watts RMS as opposed to the new Alpine SWR which is 1000 RMS. If you are on a budget to get good quality bass, these subs are a great buy. ive had these subs for over a year in parallel with a 1000 watt Rockford Fosgate D1000 amp. Im running my subs a little low but I have a lower chance of blowing them. I am a little bummed because I wish i had the newer alpine SWR's becuase of the higher wattage handling. Overall, very pleased! These subs preform phenominally in a ported box with about 1.3 cubic ft/ sub.

Awesome frequency range compared to most I looked at in my price range. Hits hard and provides a powerful nicely toned bass for all types of music, from country to rap. I would recommend this product to others and I tell all my friends exactly what kind of sub they have when they ask after their ears have been pounded.

Amazing quality out of this American Built puppy

March 17, 2012

Have one of these hooked up in my Jetta TDI. Wasn't looking for car shaking bass for this car, so the setup i got was perfect. This sub in a sealed box at 4 ohms and a hifonics brutus 1200 amp is a great combo to generate a sound that is deep and super clear and rattling in the 2006 Jetta which is what i was looking for, hitting perfect on all the songs that i blast when i am seeking a thumping bass. This sub i can tell is built with extreme quality and built to last a really long time. Highly recommended and great service from Sonic at a good price.

Best subs ever

February 14, 2012

I had bought these subs a few years back. I'm running them on the strong kenwood class d. they are in ported boxes, 2 12" in my civic. Everything would shack my back glass broke and my subs still look new. Just put the type-r in sealed boxes, even hits harder and could here it from blocks away. Also theres no radeling in the truck.

type r

November 15, 2011

i just bought mine on thursday and got it yesterday on monday wow it got here fast. i had a jl audio w6 for a while and it blew and before i got the w6 i was looking at the type-r and was interested in it but got the w6 for cheap on craigslist. I'm running a rockford fosgate prime 500 to it the same one i ran to the w6 and as far as loudness and thump the type-r has so far been deffinetly louder then the w6 was even though im still on the break in period, so many new rattles came up once i put it in my durango and i havent even had it on past 20 on the volume yet. but for sound quality the w6 seems to be far better. It hit so many more notes then the type-r seems to be able to hit and the transition between the bass notes was a lot crisper, the type-r seems to struggle transitioning between notes. type-r: louder then w6; w6: way better sound quality.

2 12" type r's

October 20, 2011

I use to have 2 12' type r's (these ones) got them at best buy when they first came out and i put them in a pretty big ported box tuned to around 33 hertz and man these things got LOUD! But keep note, the old type r's had 2 spiders and these have just 1..yet these are 100 rms more? Doesnt make sense to me but they sound great! Very good subs.

Perfect

August 10, 2010

I installed it in a Sonic 1SV12 ported box from this site, powered by a Hifonics BXi1206d at 1 ohm. It absolutely slams and takes the power like a champ. The new design looks great, sounds just as good as the older Type R, and handles more power. I couldn't ask for anything more.

Nice Product

July 2, 2010

I just installed one of these bad boys in my 09 Saturn Vue in a 0.7 cu. ft sealed box. Got a Hitron 1000w 2-Channel amp. I'm running it bridged at 4ohms. It sounds good and pounds. Still needs break in time. I highly recommend this product.

Pretty Decent Subs I gotta Admit

December 7, 2011

Pretty cool Subwoofers!!! I gotta admit when I first heard these in the car I was hype. I put them in my wifes car. They hit pretty hard i must admit!! However, I noticed that this sub struggles between notes in hitting the beat on time. The subwoofers in my other vehicle hit wayyyyy crisper than these speakers. -1 on Quality for that one. Powerful Subs though.

SINGLE Alpine Type R 12" in pvc ported box

October 18, 2011

Decided to get an alpine type-r 12" in a custom pvc ported box running off of a 2000 watt (800 fuse rated) stax amp and it bangs. Since i drive a hatchback, it rattles my whole car. Windows at my friends houses shake when i pull up and cars beside me shake too, off of a single 12. If put in a good box this sub BANGS!
