Re: adding a sub to my yamaha receiver
The Dayton Audio SUB-120 HT for $180 is a good possibility. Use a single RCA cable from the RX-E100 sub out to the right Line In on the subwoofer.
What speakers are you using? You will want to set the subwoofer crossover around the -3dB low frequency point of your loudspeakers.
