Subwoofer Specifications

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.
1800 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.
900 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
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".
85.88 dB
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.

This sub is amazing

July 13, 2007

I bought this sub from sonicelectronix at a good price. I wanted this sub to save a little room because I had 2 subs. This sub is much louder, much cleaner deeper bass. I have it hooked up to a 400 watt rms hifonics amp and wired at 8 ohms and it still wangs. This is a very good buy and if you want low, clean, solid bass then this is the sub for you. I'm very impressed with this sub and i'm not giving it the full 900 watts it recommends. For loudness and great bass this is the sub you want. I would put it up against the Kicker L7 any day.

Worth Every Penny!

January 23, 2006

I bought one of these subs just for a little extra bass. I have it hooked up to a generic mini system in my house. It is only getting about 100 watts peak from the stereo, yet it shakes THE WHOLE HOUSE. I've knocked stuff off of the wall, came close to braking my window in the room in which it is positioned, and whenever I have it up loud enough and shut the door on my room, it sounds like its going to blow the door off the hinges. Great buy! Worth every penny! Even if you're hooking it up to a generic stereo!

True power from the Gods.

December 2, 2005

I have two of these along with a HiFonics XX-Hercules amp wired at 2000W RMS @ 1 ohm in the back of my Ranger Ext. Cab... so far no one has been louder than me. Also have a Tsunami 2-farad cap, which isn't big enough cause I've had my dash lights go completely out (depending on the type of bass). The only thing that has disappointed me was after about 3 weeks after having it installed, my amp fried, which was my fault... and my subs are perfectly fine. I'm gonna get two HiFonics Brutus BX1205D amps to take the place of the Hercules. Haven't had the LED lights hooked up yet but that will change soon as I get my Brutus's. And for you Kicker lovers out there, this sub will put a 12" L7 to shame with ease, even in looks. I guarantee you will not be disappointed with this sub... as long as you have a amp to power it enough.

Great looking and performing sub

November 11, 2005

These subs are really underpriced. They hit VERY hard and VERY deep. I like them because they require a relatively small box both sealed and ported... Very clear and loud.
