Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Type-S (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.
900 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.
300 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).
30 - 700 Hz
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.
Black
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.
Glass Fiber and Pulp/Kevlar
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.
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.
0.65 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.
1.5 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 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.
1.75 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.
4.3"
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.

Excellent low bass

July 5, 2012

I put a pair of these Alpine subwoofers in a very sturdy homemade vented (a.k.a. ported) enclosure built to Alpine's "optimum vented box" dimensions from the user's manual. They are both driven by a 600-watt Alpine mono amp. The bass is very powerful and clean to well below 30 Hz. I would definitely recommend these subwoofers.

Love this sub for the money!

This sub is fantastic for the money, I like my 12" R's better, but they cost more and require more power. I would get this if I were you!

Perfect

February 16, 2012

I have installed a pair of these in my element with a small apline mrx-m50 amp about 6 months ago and these subs still have the same great sound quality. They fill my car with great bass after properly tuned. These are perfect for open cabs for most suvs. These won't be rattling the glass of the houses you drive by but they make your car wobble. These sws are great for someone who wants a moderately priced sub and yet have power to them. Aplines are made to last and thats true to their reputation. Sonic Electronix did a great job shipping them to me with nothing damaged.

This sub HITS

January 24, 2012

I own two of these subs wired at 4 ohms each driven by its own Clarion XR2110 Mono amp. WOW what an awesome combination. They hit so hard. So hard in fact that the screw down terminals loosened and the wires fell out of the sub box. I had to Loctite them down. I totally recommend these subs. They are awesome.

great subs

June 2, 2011

I have 2 of these and have had them for about 2 1/2 years now. I have them hooked up to an alpine mono amp in a sealed enclosure. I play them as loud as i can every day and they still deliver amazingly smooth yet extremely loud sound. I Will be getting these again.

Great "little" sub

May 1, 2011

I love this sub. I have a 96 Chevy 1500 standard cab truck. I had to build 2 custom boxes to go behind the seats and the only subs that I found to fit were these Alpines. Shallow mount depth, great power handling, flexible installation options with the dual voice coils, look great, and still hit hard and clear like a higher priced sub. I have a Boss Phantom PH2.800 amp pushing 260 watts RMS @4 ohms to each sub wired in series. Sounds great. Great buy for first sub or someone on a budget.

Really nice for a "budget" subwoofer

August 20, 2010

I really like this sub woofer, it is very well put together. It can hit hard and it is powered by compact class D putting out 500 watts rms. I have it tuned to put out 70 hz and below. Its frame and magnet structure is more conventional than its larger and more $$ big brothers but sound wise it is very good if you don't have the space or the budget for one of the Alpine big boys. I think it is a great investment.

May 16, 2010

When you can make the mirrors in an f350 shake or the passengers feel like they just stepped out of the message parlor, you definitely have something going good, like good ol' fashioned BASS that makes ya feel worm and tingly inside. built my own box and stuck these bad betty's in my truck and for a super crew cab these just plain rock the block..... go getchya a pair and put a smile on your face:-)

Greats Subs...Especially For The Price!

March 15, 2010

I have 2 of these subs hooked up to a Kicker 10ZX400.1 Amp. They are in a MTX Thunderform Enclosure in my Supercab Ford Ranger. I am amazed with the sound quality, and couldn't be happier. I have always been a fan of Alpine products, but these are my first set of Alpine subs. They play all types of music extremely well.

These subs really surprised me for what I paid, in combination with a 300watt mono amp. They hit extremely hard and sound clear as day. I am completely happy with my purchase and will buy alpines for my next truck as well but maybe upgrade to type rs to run a bigger amp.

Great all around sub

January 24, 2008

I'm running a single 10" type-s paired with an MTX4002 (400rms) in a sedan. The sub puts out a great range of bass. It's nothing that will rock the block (with one), but offers a great amount of bass for all music styles. I've had it for about 6 months now of some fairly heavy use and it's handled it all marvelously. I would recommend this to anyone looking for an affordable all-around GREAT sounding sub.
