Hi folks. Can i connect a sub to a sereo receiver? I am pretty much set on an Onkyo TX-8511 with Cambridge Soundworks Model Six speakers. Do you think it'll be a decent setup? Now, i'm planning to buy a subwoofer later on (hopefully PB12 or the Sony everyone's raving about). Will this work with a stereo receiver? I ask this because IIRC, only 5.1 receivers have a sub pre-out. Please help me out here!
