Especially at Ebay prices!!!! I will take up for sudiobahn as well!! I had a Alum12Q in a small sealed enclosure and it sounded pretty decent! For the price i gave for it (180 new) i think it was worth that!!!! It really wanged and sound pretty decent doing it! I think audiobahn got a bad wrap for putting their name all over every tuner (ricer) magazie ever made and having people buy one and put it some shit *** prefab box. Then with the combo of them being in all the rice mags and ppl hearing some punk with some prefab bandpass rolling around with a couple cheap *** audiobahns they got a bad name! Bu from my experience audiobahns have the potential to sound pretty good and get **** loud!!!! Key: It is all in the install!! Just like every other sub in the world!!Im just saying that if you spend $50 or $100 on an audiobahn sub then your buying the low grade audiobahn stuff like the 1000q's. Everything above that level has the ability to sound good... it's just the setups that people put them in that sound like crap. Everytime somebody says something bad about audiobahn I WILL BE HERE !!! HA HA HA!!!. They don't make the best subs in the world but they are definately worth buying.
