I have 3 10" audiobahn aw102t subs and I have no complaints. I will admit they are way over rated on what they can handle. They are rated at 450 rms a piece which is 1350 rms. I went out and bought a 1200 watt rms amp and that is too much, I have the gain turned down and I am probably sending them about 800 watts rms? I have them each in separate sealed enclosures and they pound loud and clear. From what subs I have heard they have good sq. I would say they were better then my alpine type-s I use to have. My system is way louder and cleaner than all of my friends with rockford, jbl, ma audio, and sony. I have not really heard many of the high-end subs though, I would love to hear some of RE's subs especially the XXX, to see what I am missing. I would suggest if you can hear the subs first, it would be best. My friend bought an audiobahn band pass after hearing my system and he was very disappointed. It was the worst sounding system I have heard. I guess if you buy or hear the wrong set-up you could be turned off of audiobahn, I will admit some of there stuff does sound terrible.
