Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Natural Sound (Audiobahn)
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.
800 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.
400 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.
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
24 - 1000 Hz
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".
92.1 dB
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.
Reinforced 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.
Foam
Magnet Structure
Defines the overall structure of the subwoofers magnet.

Recommended Enclosure Specifications

Optimum Sealed Box Volume
This value indicates the ideal sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in 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.
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.
5-1/4"
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.
10-7/8"

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.
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.
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.
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.
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.
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.
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.

owned 2 for 6 years

December 9, 2011

I've owned 2 of these subs for probably going on 6 years now, still same ones, and other than a little rust on the metal face ring, and some scuffs on the surrounds, they hit better than a lot of other woofer's I've heard. Don't know why people think they don't have a good frequency range, I dropped them into a prefab ported box, and they hit EVERY note I want in a 2011 Sentra, they hit perfect in a 93 MX6 too. I'm pushing maybe 600rms to both (300rms a piece) and they hit LOW and HARD! Songs like "Put On" and "Where Is This Going?" hit every note. If you put them in a spec built box they will hit better than most mainstream brands like Alpine, Pioneer, etc. Like I said, 6 years owning them and they handle whatever I throw at them, lows and mids both. For the money, you won't be disappointed. Unless you put them in a crap box to start with.

not good

October 5, 2011

Had these subs and they are not good but i sold them for more then i paid for them so that was good. I have 6.5 front speakers with a bigger magnet and voice coil. Honestly there is nothing good about these subs at all they will not hit any thing not even mid bass no matter what you amp them with and they can really mess up your amp once the voice coil blows. I tried using them in a port box to spec tuned to 35hzs and no bump at all.

March 19, 2011

I got a couple of these along with a 1200w Rockford amp for $40 from a friend. Along with most Audiobahns, they hit pretty good for what they are but can't alot of frequencies. Not bad in a nice sealed or slot ported box for a cheap daily driver setup.

Can't beat the price

January 6, 2011

I had these speakers in a small sealed box in the back of my Camaro till I flipped it multiple times. Then put them in a 97 Jimmy with huge ported box, my friend will spend 90$ on some p1's or $120 on some Pioneers. I have him beat by a good amount with $60 Audiobahns that are 5 years old. Right now there hooked up to a 1000 only pushing 185 RMS to each speaker at 4 ohms. I would have them bridged but theres no way since my amp is 2 or 4 ohm operation. I love them, going by these I would hate to see how many windows i would shatter if i got the immortal serious.

March 20, 2009

I have 2 in a sealed box running off a 1000 watt Rockford amp and the out perform my buddies Kicker Solo. I listen to mostly rock and they have a great response time, yet they still pound when I through in something with a little more bass. The guy who blew his obviously doesn't know how to hook up a dual voice coil speaker.

Good bang for your buck

October 22, 2008

If you're on a tight budget, a pair of these woofers and about a 300watt rms amplifier will usually get the job done. The subs are good and can handle lots of power. However, you don't need a ton of power to enjoy them. They were very efficient and the overall sound quality was good. There are better subs out there but these are very good for the price.

Pretty ok sub

February 20, 2008

I had 2 of these subs in a sealed enclosure with a 350-watt Rockford Fosgate amp. After I broke the subs in they really started to pound, so i bridged the amp and they pounded even harder, the only downside to these subs is that they deal out a great deal of distortion on some songs, but other than that they're great!

Good sub

July 16, 2007

My friend has one and mine is coming on Monday, good sounding sub woofer. I will have mine hooked up to a 92 RF Power 800 Amp, so SQ will hopefully be better than these hooked up to my friends Boss amp. His still sounds very very good though, hit nasty lows and crisper highs, not too high but around 500 HZ they still sound clear.

June 9, 2006

Just got these put into a 900 RMS kenwood kac9152. They start popping before I can get my volume up half way or any of the power from the amp going. May be different if I had less RMS amplifier, but these are trash.

its okay

April 18, 2006

Audiobahnn has many good subwoofers, and has good speakers. My friend owns 2 of these with a 1200 watt sony amp ( 2CH ). I would suggest this subwoofer for people with smaller cars, and a 600 watt max amp. This can't handle 700 watts with out blowing, the cone is a normal cone but for long periods of time listening to rap music above the rms, or on the rms will mess up the cone, and you don't want a subwoofer that sounds like it's dying when your listening to music. This subwoofer is cheap I gotta say. Also it sounds good and some what loud with rock, some R@B, jazz, and 2pac.
