Guys, can you suggest a top quality sub for music? I know a bad one is worse than none, so it's going to be a balance. It's not for the lounge so spending a fortune on velodyne is out of the question. Musicality and extension are way more important than spl. The sub needs to blend into some dynaudio focus 140 for low level listening. I just want subtle extension. Are there any kits for about £500 that will be decent? Otherwise I will have to wait a while to save up. Second hand is an option too, for any more mainstream subs. So far I've been told anything with a volt driver would be ideal (as used in REL studio) or that a Peerless drive is also good, as used in these...
