Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
SXXv2 (RE Audio)
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.
2400 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.
1200 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".
88 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.
24 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
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.
1.50 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.
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.
7.25"
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.
11.2"
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.

RE Audio SXXV2-12D4 is beast!!!!

March 21, 2014

Definitely recommend this sub. I bought this sub with a Hifonics Brutus 1600.1 because I had it paired with a type r but it burned out and this sub replaced it. The sub was definitely worth the $300+. My setup is a 1600.1 Brutus, RE Audio SXXV2-12D4, and a 2.6 cu inches ported box with polyfil. (Of course a cap and epicenter but that's extra.) This stuff is loud!!!! No joke forget your type r or your kicker.. it's all crap.. This my friend, is Los Angeles streets certified!!!!!!

Great Sub

February 3, 2014

I bought this sub to replace 2 kicker comp 12's so I could have more room in the backseat of my truck and it was a great decision. This sub not only puts out alot of bass but the sound quality is on point as well. I have a kicker 1000.1 pushing it and this sub doesn't even heat it up it can handle alot more power. I had to run an another batter just to keep up with those low pounds. I have had a lot of subs from kenwoods to pheonix gold and this one has out preformed them hands down. I highly recommend it.

This sub pounds!

January 19, 2014

I have this sub wired to an mrx-110 (1100w @ 2 ohms) but the birthsheet claims 1210w. It's sitting in a 2.59 cu. ft box. Had to cut the hole a little wider to fit this beast in. I'm a huge basshead, and just this one sub did it for me. It hammers. I couldn't even imagine 2 of these.

Great subs!

August 25, 2014

I wired 2 of these subs to a 1ohm final load on a Hifonics BRX2400.1D and these subs will get loud! RE is a great brand of subs and are super durable. I would recommend these to anyone looking for some tough subs that'll add quite a bit of bang for the buck. You can't go wrong!

RE subwoofers continue to impress.

April 8, 2015

Let me start by saying I never write reviews, with that being said I had to preemptively come to the site and write about my latest subwoofer which is the RE SXXv2 12". My last two previous subs were RE SRpro 15d2, and before that the RE SEX 10d2. I currently have this new subwoofer loaded in a 2 cubic foot vented box tuned to 32hz. Now to the review, this subwoofer is very well built, the basket, the spider, the voice coils, the surround, to the magnet has been built superbly. After receiving the sub I ran it through its paces for a couple hours to warm it up, coming from Hi end Home audio I typically do not have high expectations for subwoofer since they really dont start sounding good until about 20-30 hours(typically) What I heard after a couple hours with this subwoofer was astounding, not only was it visceral, but it also was extremely musical. Most Bass heads look for something that will rattle everything and break their windshield(which they brag about) this Subwoofer is definitely capable of that! I am amazed the egregious amounts of output this woofer can put out, not to mention this sub can go LOW!! Currently I have it under powered using a Power Acoustik Bamf 1600d wired 4ohm @ 760 watts. Bottom line is this: if you are ready to graduate from subs that just make loud booming noise IE: Kicker, Rockford Fosgate, Alpine, Pioneer and many others which I have owned then you need to talk a good look at RE subs. These subs will last a long time and will give you years of quality bass.

I 100% recommend this subwoofer, or two!

Sxx for now on

October 8, 2013

I got 2 of this bad boys and it's the best subs I ever owned. I had poineers champion 1000 rms,power acoustik mofo 1500 rms each. And after I put these in my car now I'm questioning if power acoustik and poineer was lying about there rms because this subs sound like 6 12's. If you thinking about getting these just go ahead and buy them. Make sure you get ofc 0 gauge wires and sound damping if you want to feel to truth power...

This sub has the best of both worlds, spl & sq! If you like ur subs loud and like hard hitting bass and planning on getting an Alpine type r dont! I blew out 2 pairs of those the spl from these subs murder alpine and the sq is nearly identical. Do yourself a favor nd save ur money and buy these You Will Not Be Dissapointed. Also this sub isnt a true 12, its really a 13 so you will have to modify ur box to fit.

February 4, 2016

I used to run my hifonics 1500 amp with a Type R 12", but then I broke that sub. I would always recommend type Rs to my friends because they are quality, good RMS, and relatively cheap. But I decided to go for a little more this time. So far, with my hifonics amp this PUMPS. The base is clear, loud, and produses a good amount of power @1 ohm stability. Great subwoofer, a little pricey, but you get what you pay for my dude!

not what I expected

November 29, 2015

For the price I understand. But to put false specs is not good. I wouldn't rate this sub over 750rms. First one I had dust cap came lose in a week . Now this one , I have 1000 rms to it on and alpine pdx 1000.1. And the amp is too much for it . Yes I know what I'm doing volume on the deck and gains on the amps all set by avolt meeter. I have 4 volt preamp out put on my deck . VVolume go's up to 50 clips at 45 . Gains on amp set at 3.8 volts at 42 volume on the deck. For bolth of my amps. Depending on what I play I can hear the sub flutter. Sometimes bottomout and I could smell the coil once . Box is tuned to the sub . All my wire isplenty thick enenough. The sub says it can take 1200rms . If I put 1200 to it it would smoke in a day. My bostom spg 555 was 1000rms and slammed so much harder . They don't make that anymore. But I wouldn't buy this brand again. Its just a temporary sub for me. (Sundown audio) (fi audio) (dd) audio.(dc audio) oriom hcca those are the real beasts. Next sub is sundown zv4

The cutout diameter can't be right. SE has it at 12.5". Anyone know the real number?
Richie on Jan 16, 2015
Best Answer: It is 12.5 and I had to cut 4, .5 inch squares out to the back of the box so it would slide in. It wasn't that hard though. You just need a small saw. It irritated me at first but the sub is amazing, so I guess it was worth the trouble
