Subwoofer Specifications

Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
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.
2200 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.
1100 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.
1 ohms
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".
90 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.
12 mm
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.
Cloth Laminated Paper
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.
Wide Foam

Recommended Enclosure Specifications

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.

I had one of these subs an WOW. I had an off brand 2000wat max amp in a duel ported box. When i pulled up to gas stations the windows would move an rattle :) awesome sub. The people who talk crap bout this sub have no idea. You dont always have to run the max power to the sub. Just gotta run true rms!!!!

Not sure what they're talking about

October 13, 2009

These subs are terrible. I originally purchased three a few years back to try to get into car audio comps. I had two of these on an audiobahn a2300hcq (2400 watt amp @13.5 volts @ 1 ohm). I blew all three speakers within a week. They can't handle 1200 rms. There's a reason the specs say 1100 watts. Needless to say, these subs were a big waste of money. Don't even get me started on shipping prices back and forth when I warrantied them. If you're in the market for these, take a look at the Digital Designs 3500 series. It's more expensive (399), but you'll save in the long run because you won't have to replace it. When I received the warranty replacements, I took one and used it as a boat anchor, the rest I gave to some high school kid that inevitably blew them as well on a much weaker amp than my own. Do not buy these speakers.

GREAT SUB!!!!!!!!!!

July 10, 2008

I owned one of these bad boys and let me tell you, this sub will BANG!!!! I was only pushing a little less than 900 watts to it and people would always be like "do you have two 12's" and they would be shocked when I showed them just one sub. This is a HEAVY sub and is very well made. I am trying to now get two and I know I will have NO problem being heard when I pull up!!!!!!!
