Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
SEX (RE Audio)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
12"
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.
600 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.
3"
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".
86.1 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 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.
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.
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.
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.
0.75 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.
1.0 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.
1.5 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.
2.0 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"
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.
11-1/4"
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.
25.1 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.
72.9 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.
0.44
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.
0.49
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.
2.8 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.
4.5
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.

One of the BEST Subs I’ve Ever Heard

September 7, 2010

The RE Audio SEX12D4 is one of the best sounding subwoofers I have ever heard. Seriously, this sub is incredible. At first I was a little skeptical about it. I had heard really good reviews about the sub, but I couldn’t get over the low price. I guess this subwoofer is in the same class as the Alpine Type-R, Kicker CVX, Rockford Fosgate P3, Pioneer Champion Pro, MTX Thunder 8500, etc… BUT I think it sound SO much better! The RE Audio SEX woofer plays LOUD. Right now I have it in a vented enclosure tuned at approximately 32 Hz and it is hands down the best sounding subwoofer I have had in my car. No matter what type of music I am listening to, it sounds great. When I’m testing my system with some Eagles – Hotel California (live version of course), the bass is the perfect amount to compliment the speakers. Not too overbearing, but just enough punch. When I put on some Hip Hop, the bass notes hit deep and I can feel the bass. This sub will sound great with all genres of music. It has some serious excursion too. I put on the Bass Mekanik – Sonic Overload CD and really tested the bass. I was really impressed. The sub was flying all over the place! Sounded much better than the several subwoofers that have been in the car before it. Don’t want to say specifically which subs it sounded better than (hint: read above), but this is definitely sounded better, and not just for SPL. I have found that the RE Audio SEX 12” sub is great for SQ as well. Currently, I have it hooked up to a Kicker 750.1 amp that stated 925 watts RMS on the birth sheet. So even if the amp is just giving the sub 750 watts RMS, this sub is still running smooth. Even though they state 600 RMS, just bring the gains down and you can hook it up to amp that put out a lot more power. Probably the safest bet to hook it up to a perfectly matched 600-watt car amplifier. Overall, I am 100% impressed and converted to RE Audio subs. For the price that Sonic Electronix has, you can’t go wrong. This is bass that I would expect to spend $400-500. Plus, I love the look of the cone. Just a simple black inverted dome with the RE logo. Simple and cool.

Amazing subwoofer

June 10, 2011

This sub is great, I own two of them in a ported box 1.75cu for each sub. I have them running on a Hifonics Brutus 1200.1 @ 1 ohm. These sound great in my suburban they hit the lows very well and get loud. Not to mention the sound quality is amazing. They are very power hungry I wish I would have gone with the 1700.1 amp. Ive pounded these subs very hard and clipped them for long periods of time to see what they can handle and they still hit hard. Amazing sub amazing service from Sonic Electronix.

Slamming.

June 5, 2011

This sub is the only sub I've ever purchased, but from hearing friends' systems, I can tell you that this is for sure the cleanest sub I've heard, while still hitting nice and hard. If only the LPF on my HU was better, I wouldn't have to worry about blowing out the two stock mids I have yet to replace! *only thing to look out for* make sure the box that you buy has a big enough diameter hole to fit this sub. If you call support, they will tell you that they have a certain box that will fit it. For me it was too late, but trust me, it's easier in the long run to just give them a ring.

Some of the best sounding subs ever

February 13, 2012

I bought these after seeing how much people on Youtube liked them, and I will agree. They are the loudest and cleanest sounding subs I have ever heard with extreme amounts of excursion. I have two of these wired to 1 ohm in a sealed box powered by an 1800w Kenwood amp and I just simply blows me away. I had two Kicker CVR's previously but these blow them out of the park. I can't wait to get my RE Audio Amp that pushes 2400w on these guys. These are a must buy item!

Best Bang for the Buck

December 6, 2011

First of all I've owned two RE XXX 12" dual 2 ohm subs now for 10 years, yes that's 10 years; and I've never had a problem with them. Second I've owned two RE SEX 10" dual 4 ohm subs for 5 years and never had a problem with them. These people are using the wrong box size and the wrong port size when applicable. These subs will handle more than 600 watts rms if they're put in the right box. They are ear splitting loud too. I let my nephew borrow my 10's and all his friends wanted to know what kind they were because you could hear him from 6 blocks away. I installed them in his Dodge Dakota Club Cab in 1.0 cubic foot boxes with 2" ports. I suggest going to reaudio.com and look at their recommendations for box and port sizes. They slammed until he had a wreck and his truck burned up, thank GOD he was ok. For this Christmas I'm installing 2 of these in a 2.50 cubic foot box with 3" ports at 34 Hz. The amp I'm going to use is a Hifonics HFi1500D. Note that the amp is 300 watts too high. However if you calculate a class "d" amp you only get 90% wattage output. One more thing I HAVE BEEN A PROFESSIONAL INSTALLER FOR 20 YEARS. Thank you.

SQ Sub

September 5, 2011

Bought these subs solely based off their T/S parameters. I'm truly disappointed as I was going for an SQL build. These are definitely SQ subs and nothing more. Running a DTR3400.1d to two subs in 5.2 cubes (before ports and bracing) tuned to ~32 hz with two 4" aeros. Not going to win any contests but the sound quality is is absolutely amazing. They definitely annihilate the lows and are able to easily and accurately reproduce them. Seeing 1100 before rise, they get a little stinky. If I were to consider a SQ build in a future, I'll definitely use these, but until then, not for me. Sold them to a buddy for and ordered an 18" SX. Maybe I'll have better luck.

Damn

September 3, 2011

Running two off a Soundstream DTR1700.1d @ 1 ohm in 5.5 cubes to 25 hz with two 4" aeros. Where my backseat should be, I have my box with my subs inverted in a Grand Prix. Eventually doubling the system and doing a wall. Anyways, by-far cleanest subs I have EVER heard and loudest for it's power rating. Annihilates the lows causing my cab to feel like a wind tunnel and still being cleaner than anything. Going from an MTX 9515, I've VERY pleased with how much better these hit the lows and are much more articulate while doing so. I really hated how "punchy" my 9500 was, where these are smooth and instantly transfer note-to-note without any transition noise, but rather just a clean sine wave.

SE subwoofer by RE Audio

August 28, 2010

My buddy has two of these and I have 2 of the REX in my 2003 quad cab truck. I was a little hesitant to buy them because I haven't heard of them in person but wow. they sound great. it blows kicker out of the water. the SE sounds great. I can't wait to try out the start of the competition line. Definitely a must buy. even though I didn't buy from here. I got my 2 12" REX and an 800.2 watt amp by RE at my sub shop for around $500. wasn't too bad at all but you always want more and I have had them for 2 months now and I already want more. lol

I bought a pair of these, and they met and exceeded all my expectations. CLEAN sound, incredible lows, and excellent excursion for a sub of its size. They put out big big sound and have very good frequency response, but like I said the lows are where these subs really shine. I am running these in a dual chamber sealed enclosure. I know it's been stated, but if you're looking to spend a lot on a sub, it would be crazy not to buy this.
