OK I think that covers just about all of my queries. Now I'm just wondering if anyone has a particular subwoofer to recommend?

I like the idea of having a complete axiom set, however I have taken a look at Hsu and SVS subs and they do seem to be highly rated. Does anyone have any comments on these subs? Also, I'm having trouble finding UK dealers for these subs. Any links would be much appreciated.

Again, thanks for the help, these message boards are indeed invaluable.
