Firstly, I have never said that Alumapro was better than Audiobahn. I think that would be rather obvious enough on its own........
The SQ capabilities of Audiobahn have been called into question several times and the general concensus of all is that the Audiobahn breaks up and does not retain clear and accurate SQ at certain power levels.
Alumapros motor structure, and patented cone design provide some of the clearest sounding woofers out there.
While Alumapro has been geared towards the SQ crowd mainly, they still have had thier share of good luck in the SPL division at the IASCA Idbl World Finals- taking 1st place with a world record of 171.0db.

To further add to this- check out the reviews from several respected Audio Mags:
"A miniature powerhouse - the Alumapro generates bass that is impressive not just in output level, but in quality and deep bass extension too. Highly recommended."
Auto Sound & Security Magazine - Feb. '00"
The Alchemy 12DVC from Alumapro handles loads of power and it plays load, low and clean, all in a relatively small enclosure. To top it all off , the 12DVC is a great looking sub. If your into good clean bass (and who isn't) you owe it to yourself to audition the Alchemy12DVC."

"...Fifteen farads for the price of 3 - WOW. What can we do with this much storage? We'll we can do away with rear batteries in most cases." Auto Sound & Security Magazine - July '99 "The results of our Autosound 2000 Test Lab test of the Alusonic line of subs were very encouraging, and we're looking forward to testing one of the BP-Series enclosures for an upcoming issue."
Carsound Magazine - Summer '99 "
The Alchemy is one of those rare delights in car audio. It not only works in a small box, but has impressively low distortion and a brutal output ability. This is the kind of performance that only happens when you mix a passion for music with serious attention to detail. Highly recommended."
Howard Doctor, Auto Sound & Security Magazine - Oct. '97 "
The Alchemy 10-inch subwoofer was delivered to us in a small bandpass enclosure. The back of the enclosure sports a clear Plexiglas panel which allows us to view the woofer in its natural habitat. The woofer itself is built like a tank: it features a beefy cast basket, a magnet that would make the North Pole jealous, and an alloy cone to boot. The overall sound quality of the Alchemy was really good. With the dainty 1.7 cubic feet enclosure it¹s nice to know you could put something else in your trunk with your subwoofer. The Alumapro Alchemy jams." Carsound Magazine - Feb. '98 "No matter how deep the "extreme" bass CD went, the 12 inch Alchemy went right down after it, all without sounding distorted. On the contrary: it always sounded clean, full and powerful. It can only be rated as Absolute First Class."
AutoHiFi, German Magazine - Jan. '98
"Alumapro is a speaker manufacturer aptly named for its rigid and vibrant aluminum alloy woofer cones. The color-anodized aluminum alloy cone not only makes for visually shocking appeal and offers an extremely rigid, lightweight material for optimum performance and superior sound reproduction."
MiniTruckin' Magazine - April '97 "
These speakers are quite unique. Instead of a paper or polypropylene cone, they feature an aluminum alloy cone. So the cone is very stiff compared to other materials and stays stiff over a wide range of temperature. Moreover, it does not absorb moisture like a paper cone would. The aluminum alloy cone offers a number of other advantages. First, it extracts heat so it serves as a heat sink for the speakers's voice coil. The coil stays cooler which enhances its power. Second, its power compression is very low so it is more dynamic. Third, the fact that the cone is more rigid and stiff, it doesn't bend or flex under high loading. As a result it delivers a harder hitting bass in small enclosures."
LowRider Magazine - Aug. '98
"Top quality can be found throughout the Alumapro subwoofer lines. Features which include rubber surround, unitized cone/voice coil construction for improved heat dissipation, poly/cotton spider, cast aluminum frame, gold-plated terminals, large magnet structure and a vented pole piece are combined to create an impressive and high-quality driver."
