I currently own a polk rm6600 setup (tiny satellites with sub) but with the lower priced polk psw250 sub, for use with my yamaha rxv795. I may upgrade at circuit city to the psw350 sub which is bigger and has an LFE output. Polk's manual advises against using this, and instead strongly pushes that you wire the sub through the left and right speaker wires (in between the speakers and the receiver). this is my current setup but I'd like to avoid this wiring mess if possible. FYI my current receiver is a yamaha rxv795 but will likely be upgrading to onkyo 696 very very very soon. Both of these receivers have a fixed crossover of 80hz I believe. I do not have a very good understanding of bass management, do not have a calibration disc, and strongly suspect that my current setup is not calibrated properly at all. HELP!!!!
