I’ve experimenting with a subwoofer connected to RCA L/R from my BHK Pre and the result has been very satisfactory. I do have two identical subs so in theory I could go full stereo. Here’s the but… the second sub is hooked up to my HT (same room but all in wall/on ceiling/in ceiling) with a dedicated AVR.
Could I hook up the AVR to the left/LF RCA in and use the right RCA from the BHK? The two systems are never on at the same time
All the settings are already identical between the two so that’s a non issue.
