Hello Everyone, Great forum!, just got into it. Well I have been hearing everyone talk so highly of the SVS subs along with other review sites and have decided that I will most likely buy one of the PCi's in the new year. Here is my situation before the question: I have a relatively small room, about 1300 ft3, 2 polk RTi38's for rears, Polk Csi130 center and DCM KX12's for mains (Timbre should be better, but all in good time) and an Onkyo501 reciever. I live in a duplex where as of now the neightbors say they can't hear a thing when I really crank it, however I am worried about that changing when I get one of those really killer subs. Does anyone have any suggestions for simple non-permanent sound insulation I can use for the sub or a suggestion on sub choices for a situation like mine? I was thinking about the SVS PCi25-31 due its smaller size and my small room, but I have also been considereing the 20-39. Will the 20-39 be that much more louder and obtrusive for my neighbors, or just hit lower notes, or would it just be un-necessary? Thanks for any help.
