More Wiring Options with Dual 6 ohm Sound Q Subwoofers

Sometimes 1, or 2 subwoofers just isn't enough and some of us decide to go with 3 subwoofers. The problem that we come up against is the final impedance and finding an amplifier to meet that impedance. Audiobahn's Dual 6 ohm configuration allows for 3 Sound Q woofers to be wired to a final impedance of 1 ohm or 4 ohms. This makes matching an amplifier must easier and convenient. One of the most interesting features is the use of multi-connect Lug Lock terminals. These terminals will allow for each terminal to have a single connection instead of the traditional combination of multiple wire into one terminal. This will improve installation ease when looking to install more than one subwoofer. This also allows for a cleaner install and decreases the chances of wires crossing and picking up unneeded signal. The Audiobahn ALUM12N is rated at 1000 watts RMS and features a spun aluminum woofer cone and EPDM rubber surround for increase excursion, stability and improved tighter, accurate response. If you are ready to experience some good sound quality then look no further than the Sound Q series from Audiobahn.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Sound Q (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.
2000 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.
1000 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.
6 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).
18 - 500 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".
97 dB
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.
Silver
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.
Aluminum
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.
EPDM Rubber
Magnet Structure
Defines the overall structure of the subwoofers magnet.
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.
No
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.
No

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
Sealed
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.
.5 cubic feet
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.
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.
2 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.
1.3 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.
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.
3.25 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.
5-5/8"
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.
11-3/8"
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.

No

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.

Great sub... so stop blowing them up!

August 16, 2011

I was a little leery of this sub due to half the reviews being poor... I have owned Audiobahn AW121T subs in the past and loved them, also a speaker to receive mixed reviews. Let me put it to rest once and for all... these speakers ROCK. Bare in mind, this is not the case if you: A> Under power them... RMS ratings are not light hearted suggestions, +/- 20% of the RMS wattage at the MOST is acceptable. Under-powering speakers is worse than overpowering them! I have a rated ~1000w rms in a 1.2cf box with poly fill and it's not even strained (and this is during BREAK-IN). B> Don't break them in... breaking these subs in is definitely not optional. C> Wire them wrong... this can wire down to a 1.5ohm load if you have 2 of them, if you're not running a class D amp, you'll have some issues. As I mentioned I am running this sub in a sealed box and my goodness, the clarity is top notch. It's punchy, smooth, clear, and it still hits very low. Without a doubt the best value on the market today. With less than 25% bass boost from my amplifier, I hit 122dB without trying too hard. That's with ONE of these little monsters. Don't let the price fool you, this is a top notch product. It looks great to boot! Picture do it no justice. Buy one and see for yourself!

July 31, 2012

i bought 2 of these and wired them up in 6 ohms on a Kenwood class d 1000watt amp an i have the amp turned all the way up. WOOW... thats all i have to say. the sound is sooo clear. no distortion at all. and when it hits the lows its soo loud, the skin literally shakes on your arms. I built my own custom slot ported enclosure tuned at 40hz with 5 cubic inches internal. these bad boys have even out beaten my friends jl w7. Ive had them for about months now and still no problems at all. greeaatt product.

Good build quality and accurate specs.

January 6, 2012

I have three Audiobahn ALUM12's wired in parallel operating at 1 ohm coupled to a 3000 watt class D amplifier. I have not had any problem with the subwoofers, in fact they seem to laugh at the meager power supply. I had to buy the Audiobahn after melting the voice coils in the Boss Chaos extreme subwoofer with there 1500 watt rating (ha) didn't even last a minute.

Fast shippin and looks great! Nice crate for them to insure no damage! Love the speakers so far. I haven't hooked them up will write a new review once I do but plan to buy 2 more and have 4 in an acura integra so best of luck should slam hard! Little rust on inside the magnet on one of them but the other than that looks good.

Update

August 20, 2011

I suspected these subs were overrated and I was right. Not long after installing a second, I matched the gains to the input such that the amplifier would conceivably put out its rated power at max volume with no distortion. That should equate to about 700W per channel from my Hifonics amp. Bass was good and loud with quality to match, but it wasn't to be. I had one die a smoky death about a month after the install. The other one probably wasn't far behind, but I took it easy on it after that. An Autopsy revealed what I suspected, a crispy fried voice coil. Much to my surprise, the voice coil is only 2.5", not the advertised 3". It paled in comparison to my RE SX12 3" voice coil (also rated at 1000W RMS), so the proof is in the pudding that these are grossly overrated. I still stand behind my opinion that these are great subs for the money. Just go in knowing that these can probably handle 400-500W RMS at best (still pretty respectable) and you'll be more than pleased. Even with the voice coil charred to a black charcoal mess, there was no discoloration on the aluminum cone; so not sure what the other reviewer had encountered.

Great subs

May 18, 2011

These are practically being given away at this price. Subs are an awesome blend of sound quality and SPL. I have one in a 2.0cf ported box tuned to 33 hz. It replaced an RE Audio SX12 (at over twice the price) which fried after a couple years. The Alum12 sounds better, but doesn't get as loud at VERY low frequencies (less than 40hz). That's expected as it's half the size, and a fraction of the cost. The sound quality more than makes up for that, and the volume throughout the range of frequencies (30-80hz) is very balanced. The bass is accurate and tight even in a ported enclosure. I don't think these are capable of 1000w RMS for long periods. If you can place fault on Audiobahn for anything, it's for overrating them. I have the one sub hooked to a Hifonics BXI1608D where it's getting about 825W RMS at 3 ohms and it's plenty for this sub. I don't play it as loud as it could go, because I think it's possible you could damage it at that power. I don't want to find out because I have a second sub waiting to go in the car as soon as I build an enclosure for it. With two subs, they should be running about 1400w to the two (1.5 ohm mono) which I will be more than happy with! It should be known that I owned two Alum12Q's 7 or 8 years ago in sealed enclosures. I later sold them and after owning a couple sets of more expensive subs since, I'm back to these and happier than ever. If they would get rid of all the flashy chrome, it would be to their advantage IMO. There is a such thing as trying TOO hard.

Nice, efficient sub

January 25, 2008

Originally I got this sub a few years back on a recommendation from a friend of mine. At the time I had just 1 JL Audio in a 2000 Toyota Corolla. I was very skeptical, but as soon as we did the swap out, the difference was obvious, and amazing. While I could actually turn my radio up just about all the way when the JL sub was in, I could never get volume more than 3/4 of the way up once we put the Alum12 in it's place. More recently I had it connected into a Ford Fusion, and even with the volume half way up on the radio and only about 120 watts going to the sub, you could hear the bass resonate over a block away. Also, the fact that sub hits bass tones as low as 18Hz is a plus. Audiobahn always makes a good product, and this one is efficient and very affordable.

Clean and accurate, Yet loud and proud!

December 1, 2005

I have 3 of these running at a 1 ohm load on my Hifonics BX2005. The amp itself is not the cleanest being a Class-D, but still, these subs sound awesome. They hit just about any note between 25- 600hz with precision. But, say you want to bump your stuff? No problem there either. These are built so well, it's hard to believe they're as cheap as they are. The quality is awesome, and their strong. You can blast the crap out of them and get stoopid' loud, or tone it down a bit and they sound awesome for sound quality. Not to mention, they look sick!
