System: Receiver: Sony STR-DB830 Screen: Panasonic PLasma:ST 42- PW4 Sub: Paradigm PS1000 (130W) Fronts: KEF Q35.2 floorstanders Rears: KEF Q:compact Centre KEF Q 80C Am thinking of replacing my sub for a new one. Considering KEF PSW2500 to fit in with my current system. It is a fairly large room - 4.5m x 7m. Only reason I am replacing the Paradigm is it is too large and ugly for the front room (according to the missus) - hence the KEF in a nice appple finish to match the rest of my speaker set-up. Also considering the REL Quake but am concerned it may be to small for the room - or should I go up to the PSW3500? please advise.
