Ok... well, since I may not want to wait much longer, just a few more questions. I may go with one of the 12's - I'm really going for SQ though, so how does the SQ of the 12s compare with the SQ of the 10? Also, how does the low frequency extension compare? I really want to make the bass sound like part of the song, rather than have it sound like someone added a bass track to the CD I'm listening to. Please let me know your recommendation. fyi I have 2 6.5s up front powered by a separate amp, just to give you an idea of what sort of sound the rest of my system will be putting out. Thanks
