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.
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).
31 - 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.

Hmmm, think again

September 12, 2011

This driver has a defined rattle to it. I've had it in a sealed and a ported box both matched to it in specs. It is underpowered at the moment and I have given up on locating the source of the rattle. Now it's time for another brand.

Impressive!

September 26, 2012

This is the first Alpine sub I've installed. More often than not I try to go with JL but this system was built on a budget. The quality of the subwoofer is what I found most impressive. You can tell Alpine took the time to craft this jewel. Doesn't seem cheap at all and produces decent bass for the price. It won't rattle your eyeballs loose but will certainly add some depth to any system without overpowering even stock components. Overall for the price, it's a damn good value.

Incredible Value, awesome sound

August 17, 2012

This sub hits so incredibly well. It is better than most subs with even a few hundred more watts on it. I've heard it at full power and chose to lower it to half for my tiny hatchback! It still rolls down my manual windows and tilts my mirrors. The sound is clear and hits properly at any tested audio range. Highly recommend this product!!!!

Bad sound quality

March 17, 2012

If you're looking for sound quality, you'll have to look elsewhere, this isn't your subwoofer for SQ. It gets loud and boomy, and anyone reviewing this product with 5/5 on everything only cares about volume, but not sound quality. People might write "it shakes my car man" or "it slams so hard" which it does do well. It does get loud indeed if that's what you're looking for in a cheap/value/budget subwoofer. The subwoofer does look nice though, and the material is tough.

I bought 2 of them and had them boomin for about 4 months. Then one just stopped working. Customer support is wonderful they gave me credit and got it replaced. Then the other went up in smokes one month after being paired with the replacement. Sent it back then the next day the replacement stopped working. Didnt change any settings on the amp. Will not be purchasing these subs anymore.

Great sound at a great price

June 22, 2011

At first I was unsure of whether the Alpine PDX5 amplifier would power two 1043D's enough to produce decent bass in my sedan. I was pleasantly surprised by the volume and by the frequencies that this combination could achieve. I prefer clear and balanced music in my vehicle over making myself deaf and these subs achieved my goal. Combined with the Imprint processor, Alpine has caused me to want to listen to all my favorite songs over again because I have never heard them sound this great. This sub is great for mid-level price consumers who aren't looking to win any stereo competitions but appreciate cranking music on a trip or at the beach. Loud enough to irritate the neighbors.

Great sound! Shallow mount perfect for a pickup truck!

May 31, 2011

I put 1-10" under the rear seat of my 2010 Silverado Along with all Polk 6.5's in the doors and a 5 channel Eclipse amp. Sounds great with RMS power. Clean and can go fairly deep for just a single 10". The shallow mounting depth made it easy to find a box for under seat application. Great over all value!

Great tight sounding sub!

February 14, 2011

I have put this sub in two different boxes. One was designed for under the seat and immediately I was underwhelmed at the response of the sub. Having said that the box was only around .45 cubic feet. The second box I designed was around .90 cubic feet and the sub came alive! It's a wonderful sub for snappy quick responses but it does lag a bit on the deep stuff. Perhaps pushing the volume out to 1.2 cubes would be a bit better for the lower frequencies. So, it's a great value and great sound but for a shallow mount sub, it requires a pretty big box.

Great Sub

September 21, 2010

These subs hit like a set of JL Audio W3s which are about 3 times more. Very shallow mount depth which is good for behind the seats in a truck (like mine) I custom built 2 sealed boxes for them at about .65 cubic feet each and they hit great. Loud and clear. I am pushing 260W RMS to them and they can handle much more. Love them and would recommend them to anyone

2 Alpine S 10" subs in a 99 Chevy S10 with a Profile 1000W Amp

February 26, 2009

I recommend. The cab shakes like a club floor on springs when the beast is let loose. I keep the bass boost to 0 or 1 and the sub volume varies per song but they sound great. I got them in a sealed box. You can hear them down the block when my car is parked and blasting.
