Hi This is my current setup: CA 640CV2 CA 640AV2 Mordaunt Short 908i (FS with side firing subs) QED Silver Anniv XT Biwire QED Qunex 4 Interconnects (Samsung DVD player connected to Amp) I am fairly pleased with the sound of the above "budget" system but desire a deeper bass & pronounced mids. I wish to purchase either the MS 309i or the Wharfedale SW150 (which are within my budget & more easily available where I stay). The SW150 looks better on paper, but is buying a sub really going to make up for the seeming gaps in the current setup/ Is it worth the extra money spent? Those who own either of these, will they recommend it for a 2.1 setup? (Any other models (like Polk) which can work out to be better?) Thanks
