Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
SXX (RE Audio)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
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.
1000 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.
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.
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".
85.2 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.
22 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.
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.
Dual Composite 2-Piece Cone
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.
Rubatek Foam
Magnet Structure
Defines the overall structure of the subwoofers magnet.
Triple Stacked
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.
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.

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
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.
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.
1.25 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.
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.
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.


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.
30.7 Hz
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.
21.8 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.
1.9 ohms
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.

Worth it

January 27, 2011

I bought one of these and put it in a 1.7 cubic feet box with a 4" aero port and this thing goes low, I had a jl w3 15 and this thing goes lower and sounds better doing it. I would strongly recomend putting 1200-1500 watts rms to it because it takes it and has awesome sq.

wow!! Just took two boston 15's out of my car because they didn't sound right, nothing against Boston. These particular subs just didn't have the sq i was looking for. I bought this sub a mounth ago. didn't know what to do with it. Price was just too good to pass on. long story short, I replaced two 15's with this single 10" and i was speechless. Have it in vented box on brutus1200.1 @ 1 ohm. All of wich i got from sonic!! This sub has better SQ than the Alpine, Boston, and Kicker subs i'v had. I'm getting another one ASAP. This was my first RE audio purchace and it wont be my last. Great quality subwoofer. I havent found any cons to it yet. I would recomend this to anyone.

Best sub ever

March 13, 2012

I've had this sub in my truck for about 5 months now and I love it! It was in a custom built box tuned to 32 htz and sounded amazing. It's louder and has better sound quality than all my friends that have multiple subs. I recently upgraded to 2 of the monsters and it's just crazy loud. I have them running off 2000rms and it's insane and still sounds perfect. Stay away from kicker bs if you want sound quality and spl, this sub is for you.

Great Speaker

May 19, 2013

I have always been a fan of JL Audio and have not bought anything since I became a fan. But since I have been living in Japan, speakers are hard to come by, so I found this site, read the reviews for RE Audio and thought I would give them a try. Best money spent, sounds as good if not better than JL Audio speakers. I would definitely recommend this speaker to anyone on a budget. I built a ported box using the RE Box calculator (can google it) and I could not be happier. Great speaker and great sound!!

I am a first-time subwoofer owner and this is an excellent piece to add to your system. Hooked it up to a Hifonics amp 1200 watts @ 2 ohms and all I can say is damn. A few of my buddies swore it was at least a 12 in the trunk. I have a 1997 BMW 328i convertible and suprisingly with the top down it still has nice punch. It definately has a good range and i was able to fit it in a ported box suppled by this website even with the limited convertible trunk room. I also did some research and i read that people are wiring these subs between 1200 and 1500 watts so it can definately take a beating.

This sub hits some serious lows even in a smaller L ported enclosure tuned to 34hz powered by the NVX 1200.1JAD amp. the amp throws the power and this thing takes every watt through the car and myself.Serious boom from a 10. Going for 2 next.

September 22, 2011

I had one of these in my 05' explorer powered by a Kenwood Excelon (XR-1S) that amp was pushing about 700-750 RMS in a port box. HOLY WOW ! I know there are guys out there running 1000+ RMS on these subs all day long... this sub drops bottom, and is quick to hit also. I listen to rap, rock, metal, and country - deff a dynamic sub. my friends called it the "Baby Boom Box" lol. This sub was out performing some friends 12's with no problem !!! You wont be disappointed with this sub !!!

I was in the market for another subwoofer that could outperform my kicker L7 and i definitely found it!! i had a 10" kicker L7 in a 1.7ft3 ported box tuned to 32 hz and it hit pretty hard for a 10. i had it running on an old school rockford fosgate power 800a2. i found the re sxx 10 on sonic, looked at the specs and price and jumped. i built a custom box for it to fit in my mustang convertible at 1.6ft3 and tuned it to 30 hz. that thing slams hard! it sounds like i have at least 2 10's in my car. i am really shocked at the low bass output of this thing. when i say low bass, i mean 30-40 will audibly play down to 25 hz. i know re recommends only 1.25ft3 but i really like super low bass and smooth response. i have a couple of box building programs so i played around with enclosure and port sizes and that is what i came up with to fit the sound that i wanted. for those of you who really like extended low bass response go with this size: 1.6ft3 with a 4" port 20.5 inches long. i used an aeroport. i know there are a lot of other subs that perform as well or better ie, DD, FI, ORION HCCA, but factor in the cost of those subs and you will see why i went with SXX. one more thing... make sure you have enough power to run this thing. the 1000 watts rms rating of this sub is no can handle all the power of my rockford power 800a2 amp with grace. if you choose to go with a pair of these, you need to pump them at least 1500 rms, if not your wasting your time. if you have the power and put it in the right box you will absolutely love it!! BUY EM!!!!!!!!!!!
