I have a fairly high end (by Primare standards) surround setup which is driving a Jamo Concert surround setup (Primare D30.2 driving Jamo Concert 11's as the fronts; Concert Centre in the middle and Concert Surrounds at the back). I have a P30 doing the decoding so no possibilities to add more speakers. I have been thinking for some time about getting a sub to complement this lot. This would primarily be for watching DVDs, but I guess if it were possible to integrate it into the sound of the concert 11s for normal 2 channel audio that would be a plus point. I had thought of getting a Jamo Concert sub but in spite of monitoring eBay for several years, i've never seen one of these go past, so i've just about given up. Any ideas what would be a good match? i'd prefer to buy something second hand for ££ reasons. The listening room is currently about 7m x 4-5m (but may expand to about 7m x 8m if / when an interior wall goes).
