Just got a new receiver (Denon AVR 891) and until I can afford new speakers will hook up my Polk RM6000 and PSW202 subwoofer. Should I use banana plugs? Will I have any problems using the wiring scheme recommended by Polk, i.e., connecting RF and LF to the speaker level inputs of the subwoofer, etc.. Thanks. I feel a little out of my depth with this new receiver.
