OK so I guess it is the HD3 15's on 2 AQ2200's. Nobody has been able to convince me that the L7's or Type R's would get louder than the HD3's, really nobody has been able to convince me that the R's or L7's will even take the power I want to give them on a daily basis, If i was going with half the power then I would probably be leaning more towards one of them, i am sure that they would be at least as loud as the HD3 on 1-1.5kws but I think at 2-2.5 kws the HD3 will get louder and take the power will more ease where the other 2 will be straining. Unless somebody can prove to me that I am wrong about the Alpine and Kicker subs.
