personally i still rave about the JL stuff..... their subs in particular, i had a sony 1200w sub hooked upto a kenwood 400watt amp for a while and it sounded ok, changed the sub for a JL w0 which is rated at 125w and it blew the sony away, the sound quality of them is, IMO, immense.
granted they have gotten a bit too comercial these days, but the subs still rock!!!
