Nothing Competes with the Audiobahn Immortal Subwoofers

When you hear the word Immortal you automatically think, "will never die". This can also be said for the Immortal series subwoofer by Audiobahn. Designed as a competition woofer for hard hitting bass reproduction, this woofer features an RMS power rating of 2250 watts. The woofer also features an ultra light 2-layer carbon fiber Kevlar cone, that is both rigid and lightweight. This allows easier movement which creates improved accurate sound and lower power consumption. The proprietary tall excursion foam surround adds strength to the cone structure during those hard hitting lower frequency responses. This Immortal series subwoofer doesn't just sound great but it also looks great with a chrome-plated 3-dimensional cast aluminum basket. This subwoofer was not made for the faint at heart, if you are ready to take your bass to the competition level, then look no further than the Audiobahn AWIS15P to meet your SPL needs.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
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.
4500 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.
2250 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
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).
20 - 700 Hz
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".
97 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.
Kevlar Reinforced Pulp (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.
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.
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.

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.

Sure Winner

May 4, 2005

This subwoofer went above and beyond the call of duty for me. I find is funny when i pull up behind someone and they almost break their necks trying to see who is it shaking their floor and mirrors. I had one lady roll up the windows and flip me off, these are some spectacular speakers if you like it loud.

Good Sub

August 29, 2007

I have one of these subs and they are great! If you want this sub, you will have to get a big box, it will enhance the bass. I can't even sit in the car when ever the sub is playing. If you want a sub for pure SPL, I recommend this sub.

Awesome sub

February 6, 2005

This is a great sub. Yes, it is quite expensive, but you would pay much more for it elsewhere. It is a great spl sub for this price. I have a Boss RIPD3 amp running it, yeah yeah I know, Boss amps. But the amp bumps it and the sub sounds really good. I have it in a bandpass box, which kinda sucks, I didn't have the time to build my own, but if you could build a box to the specs of this sub I dont know how loud it can get. I prolly have 1000 watts, maybe a little more running into it and it bumps it really well. I couldn't imagine putting the 2250 rms wattage to it. However, it is quad voice coil. If you are looking for spl, I would recommend this sub.

I have 4 of these in my Audi A4 - I have them hooked up to 2 Audiobahn A4KDN 4000 Watt Amps - So im running these at 2000 watt RMS Each, not the full 2250 - I have a total of 8000W RMS of sheer Audiobahn Bass, and believe me when i say this, NOTHING even comes close to these!! I cant even turn the volume up half way coz theres 2 much bass. AMAZING SUBS!!
