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.
10"
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).
26 - 600 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".
83 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 Reinforced Pulp (Paper)
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.
HAMR Rubber Surround
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.
No
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.
0.5 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.
0.8 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.
0.6 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.
1.3 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.
6-7/8"
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.
9-1/8"
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.

Alpine Type R

January 26, 2010

I have always had alpine speakers. From my door speakers to my subs, i always rely on alpine. before i bought my alpine 10 type r i had two 12 type s which were alright, but i wanted more trunk space so i decided to go with that one. I advise ANYONE to go with this speaker..one type R matches up with 2 type s, or 3 type e, and plus you dont have to go crazy and buy the type x because type r sounds just as good for half the price. i recommend this product to everyone.

May 3, 2012

I got my 2 Alpine Type R's from someone for around 50 bucks a piece. They're still in great shape and they seriously sound like I have some 12"s in the trunk, and they beat my friend's 15" Kickers, and I'm only running 700 watts RMS @ 1 ohm. lol

alpine type r 10"

December 10, 2011

I would recommend these speakers for one reason they will out last Kicker and MTX. I got mine 4 years ago almost five and they sound great. My 1 brother bought his kicker 12S around the same time and my buddy got his mtx a year after me. They're both only running 800 watts with ported boxes where I'm running a 1200watts Sony amp bridged with a non ported box. My brother crapped out a year ago and my buddies crapped out 2 years after. It will be 5 years on my birthday witch is a few days from now. I would recommend these to anyone wanting a sub that lasts.

Amazing Quality A+++ Long Lasting

November 18, 2011

These subs are great. I have always had alpine subs and obviously would recommend them. My first subs were 2 12" Type R in a medium size ported box. It hit hard but the box was more SQL rather than SPL. I hit 137 db on SPL meter with them w/ 400 watts per sub (Hifonics Mono 1206d amp, 1200watts)

Next, i bought an Alpine Type X- 12". One of these in a large ported box, same amp. I hit 143 dbs on the meter. Stupid loud and MUCH louder than the two Type-Rs but with only one sub. Too bad the sub was stupid heavy (like 75+lbs in the box) So i sold it and got more than i paid for it.

I then got a 10" type-R for cheap on this website. I put it in a home made, large, ported SPL box and hit 145dbs on the meter with 2000watts RMS going to it. This was just for fun. But it didn't even blow the sub!!! I hooked it back up to the Hifonics amp and put it into a small ported box later and it's still going strong over 3 years later. Awesome SQL (sound quality) and great for SPL (Sound pressure level- In a way, Loudness)

This sub is great for anybody looking for window shaking, ear tickeling, license plate ratteling bass- to the daily driver listening to hiphop/rap music on the way to school or work, just looking for moderate bass that sounds great!

February 27, 2011

I have a set of the Alpine Type R tens and believe me, you will never want another brand of sub woofer. They hit so hard you would not think they was just tens i'd design my own custom box in 95 j30 Infiniti, and they sound great, I sound tested, I'm hitting at a163dBs on a 1200 watt Brutus at 1ohm. That's what I'm talking about. So if you really love clean good premium sound you have to get a set of these.

October 9, 2010

I have one 10" Type R and one 12" Type R in my 1992 Dodge Power Ram sittin behind the seats and for a single cab truck it bumps super hard, much harder then when i had two 12" kicker comps in it, I think I'll be keeping this set up for the rest of my life haha! But for real listen to everything from country to rap to classic rock and it doesn't matter what music is playing on these subs it just sounds amazing at all times of day and i am very proud of my system also!!

never ever doubt alpine.

September 23, 2010

I bought these 6 months ago, and they still sound perfect. Very good Product. i get doubtful whenever i buy things until i try them out. I hooked 2 of these up to a sundown saz-1000d @ 1ohm (1000w rms) in a ported box supposedly tuned to 33hz. I probably have it turned down to 800w or less because my alt cant supply the full power. these things really slam. i wasn't going for loud but that's what i got and it sounds good and clean. i was mixed up between these, and the jl w3's, but i am very happy with the decision i made. be prepared to fix rattles in your car. it'll make it sound much better. give them good clean power, tune your amp right and these will play for a long long time. (stay away from bass boost)

ABSOLUTELY SICK!!!!

June 7, 2010

You cant go wrong with alpine anything and these are my second pair(last ones stolen). I have friends with fosgates,explodes,pioneers, and nothing in its class are as loud as these are. There subs can actually be hooked up in an 8ohm pair if you have the money because it takes 2 amps(like me), I consider myself an audiophile and I listen to a wide range of music from hardcore to rap, alternative ect. If you want the best quality speaker that has the ability to be the loudest ones out there look no further. I swear by Alpine i have alpine head unit, type R component speakers amp and subs they are the best!!

February 26, 2010

These subs are simply amazing. I had a single type-r 12 before upgrading to 2 of these baby's. I have them hooked up to the Power Acoustik LFA2-2600 2-channel amp with both subs at 2 ohms. The amp is a perfect match to the RMS power needs of this sub. The bass is loud, proud, and very tight in the sealed box I have them in. Best part is it's not so noticeable out of the car because of all the dynamat I have throughout the vehicle.

The Alpine Type R 10" subwoofer ROCKS. Awesome quality, great price, and killer BASS. Big DEEP sound in a ported enclosure, tight hard hits in a sealed box. I have this sub in a ported enclosure with 400watts RMS @ 2ohms, and it bumps hard. Just one of these subs will get the job done. Excellent SPL and SQ. A very high quality sub at an affordable price.
