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.
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 - 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
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.
.85 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.
.85 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.
1.70 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.
1.70 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.

Gread Sub

July 11, 2010

I have two of these subs running them at 600W at 1 ohm each for about two years now. You need to dynamat your trunk and your shelf if you do not want you trunk to rattle. I also have it filled with foam, and license plate on a two side scotch tape. At first i had it in a sealed box, and in about a year moved them 3.4 vented (inside volume not outside) 1.7 per speaker. They play lower and louder in a vented box also creating more pressure. I got to say that two of these might be an overkill but for me overkill is under rated.

Alpine Type-R 12" DVC 2ohm

March 3, 2010

This is a quality and reliable subwoofer for a good price. Everywhere else I checked this sub was priced at $200, got it here for much less. Have it paired up with an Alpine V-power 500w mono amp and it has handled just about anything i've thrown at it. Good investment for someone looking to add good bass to there ride.

Couldnt have asked for a better purchase.

March 3, 2010

At first I had been skeptical because of the low prices but boy was I wrong. After waiting a short two weeks my package finally arrived. They were everything I had hoped for. And setting them up was easy too. Pros: Low price, Perfect product Cons: Length of time waited( it was 2 50 lb. boxes) other than that none.

Much better than I thought

February 26, 2010

Set up: pioneer HU 2 type r's Sound storm 2600 mono Kole Audio cap Absolute sealed box Just got these hooked up yesterday (2-25-10) and holy hell they hit so hard I can't hear anything inside my car. Got them in a sealed box 1.8 cu per chamber running at 1ohm. I was a little leary on buying these cause I never owned anything Alpine but my dad has a 10" type S and after hearing that I wanted the 12 and take it a step further. I have owned many subs DD, Sony, Bazooka, Kenwood, and the list goes on but non seemed impressed me until these. If you want some major bang for your buck I recommend get two of these bad boys and you won't regret it I sure don't. But get them from sonic best price you will find anywhere. Went to a local audio shop and they wanted $250 for one!!

February 19, 2010

These things have been banging away great for about a year now. I have them hooked up to a 2000 watt Rockford amp that is gained down to half it's peak output. They 2x type R's sound much better than the 1x JL w7 that they replaced. The bass is much tighter and hits harder. The pair also cost less than the w7.

Unexpected.

January 2, 2010

me and my buddy are putting our systems together and he went with the two type r 12 2 ohms subs they are powered by a power acoustik bamf 2000/1d getting about 450 rms to each sub @ 2 ohms (not broken in yet).... in a pre fab ported box. WOW these things POUND. i sat in the back seat the first day he got them and i found it hard to breath. my other buddy has L7 12's 750 rms each with a jbl 1500 rms amp @ 2 ohms. these Alpines compare. believe it or not they might be just as loud as the L7's. I have kicker cvr 12's (waiting on the zx750.1) i thought my set up would be louder but then i heard the r's and they took my confidence right away from me. great sub dirt cheap on Sonic.
