I can not wait until I can get a pair of these 15's and run them on the AQ 2000's. If they are better than the original HD3 I will be more than satisfied. The only problem is I still have 2 HD3 15's and I do not see them failing anytime soon. I guess I can have a pair of both. What would be a good amount of power to send one of these 15's for daily groundpounding, 2-3kws or more. Should the new AQ 2000's, one amp per sub do them justice? I did not feel like reading the whole thread, so how does this compare to the BTL?
