Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
SRX (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.
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.
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
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.
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.
Kraft Pulp
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.
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
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.
0.35 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.
0.5 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.
0.65 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.
1.0 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.
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.

Still bangin!

March 15, 2011

In addition to my previous review, I have it running on 450Wrms@1ohm. Not recommended I know, but it has taken it like a champ daily for months with no ill effects. I listen to mostly Hiphop/Dubstep so it puts in a hard days work. And the Bose deck/speakers the van came with definitely can't keep up! Mmmmmmmmm, new HU/components:)

This sub was great! This thing can take every bit of 300 RMS. I have it running at 400 and it still hasnt blown! I will definitely be buying another. I have it hooked up to the Visonik mono amp that can put out 600 rms at 2 ohms that i also go from sonic

Buy this sub. It's bangin!

October 23, 2010

I love this sub. It is in a custom (sealed) console I built for my 05 Montana SV6 and it sounds great! I listen to a variety of music and it plays it all excellently. Tight, clean, hard hits for fast bass/kick drums but also shakes the seats on the deep lows. Excellent low frequency response for a 10" sub. I have it paired with the MB Quart RAB 1450 so it has lots of power. I can't comment on durability as I am still breaking it in. From what I have seen and heard, RE tends to underrate the power handling of their drivers. I have heard of people who gave this woofer (older model year) 400rms daily with no issues.

Pairs well with the premium Bose setup the van came with, for now. I think (know) once it is broken in and ready to fully pound, I am gonna need to upgrade the components/HU to keep up.

Bummer, more gear ;)

Bronx, NY

Great sub for the price !

October 9, 2010

Never knew about RE Audio until a couple of weeks ago from online research. I blew my 2 12s, Audiobahn, which were like 5 years old and needed something stronger.

I saw this here and found a box to the specs Re.A. recommend, got everything in 3-4 days and WOW, these things BUMP !

Got them running on a 300rms @ 4 ohms Kenwood amp and they sound MEAN. I can imagine after breaking them in and with a stronger amp.

I really recommend RE Audio to anyone. I'll soon be upgrading to one of their digital amps !

2 thumbs up.

RE audio!

February 1, 2011

This is a very nice sub very good sound rele pounds I'm going to order another one of these and a se-x for my full system. I really think these are a good buy for someone who wants good quality and sound for a good price. I like 10 in, because I can fit them almost anywhere. I think these things will be able to handle more then 300 watts RMS after its broken in, but im not one to push what they say they can do. if you want a good little sub, buy this...

Awesome sub

July 7, 2013

This sub exceeded far beyond my expectations, it hits low and hard with minimal wattage and takes more power then rated. i had it on an alpine mrp-m500 in a 1.10 cu ft ported box (after displacement) and it sounded phenomenal. i ended up selling it to try the sex and now im selling the sex to try the sxx! THERE ALL AMAZING
