I have a paradigm PDR-12 (150W RMS / 450 Peak) and it was "assisted" w/ a no name 60W RMS sub... now I have sold this sub which was part of a "surround package" and it doesn't sound as good with only one sub

My question is... should I buy a second PDR-12 or PS-1000 (200RMS / 750Peak) or sell my PDR and only get one PW-2200 (400W RMS/1500Peak) ????
