Thanks everyone for the prompt replies, this has indeed helped and I shall purchase a subwoofer as soon as I can fund it. One more query (Purely as a matter of interest) The volume control on my receiver appears to be measured in db. I.e. A very quiet volume is around -40.0db, and 0.0db is, as i consider, a very loud volume. What is the effect of going above 0.0db? Is this when distortion begins from the amplifier? Thanks.
