I know I like 10s... I have had 8s, 12s, and 15s ... 10s seem to work best for me.... is there 1 or 2 subs that most people agree on, that sounds best? Now, I really don't care about volume, heck, 120db is louder than a typical concert (I know, I have been the guy behind the board for a few bands), and 120db is easy in the car... all I really care about is the SQ .... So, what would everyone suggest I try to listen to? No need to worry about how much power I will give it, etc, as I don't have an amp yet, but I do like the Audison 5.1k (750 into 4ohm, 1,xxx into 2). Thanks!
