I've just bought a second hand sub woofer, Looking at the connections it has two RCA inputs on the back of the sub. But my AV receiver only has a single rca sub woofer out.
Am I right in thinking I can pick up an adapter from DSE to merge the two channels together. And is there any loss of quality for doing so?
Another question is What should I set the crossover to? My Kef C5 floor speakers aren't big on bass, so I would like most of it to go to the sub woofer.
