Thanks all for your replies. This is a great forum and I always end up learning an aweful lot just by reading through all the posts...can't say I understand them all but I learn what I can!

I'll put up a post once my sub is delivered and I have a chance to play around with it. Right now I"m trying to figure out what I"m going to listen to first in order to test it out. Matrix I or II? Led Zep DVD? Roger Waters In the Flesh? Some good bass heavy TOOL? Maybe I'll just take a day off of work and listen to them all at once!
