It's Audiobahn... haha What do you want to know about it? Prob not bad for the price, but you can prob do better. Another bad thing about the Alum's, is they have 6 ohm dvc voice coils.
Wow, I cant believe the crap I hear on this forum about about audiobahn. comp vr's over alumq's?, wow, that is just ridiculous. Shane, that is a great woofer with a very good sql ratio. Also, having dual 6ohm coils is good because you can run a 3ohm load for a class ab amp or a pair to run a 1.5 ohm load with a class d amp. Either way, I've owned many audiobahn woofers and contrarily to what people think around here, the alum q is a great buy and i'm sure you'll be happy with it.
