Hi guys I have only recently found this site and after looking through a few threads re: subwoofers I would like to ask your advice. I am looking to buy a sub for my sound system but don't really have a clue what to look for... my current setup comprises: Sony STR DB940 amp KEF Q series speakers (pair of Q8s rears, similar to a Q6c centre speaker and a pair of similar-looking Q7 front speakers although they dont have the lower of the two cones). When I get home from work tonight I will post the *actual* specs of the front and centre speakers. My budget would be a maximum of £300. TIA Moby.
