I currently have a Denon 4520 AVR with dual RCA sub-outs and am running twin JTR S1's using their XLR input - (since thats the only option). I noticed using this connection that the sub levels are very poor and require higher trim setting to gain more output. I am comparing this to my dual SVS SB13's that was connected prior. My setting are much higher in the AVR, to get the same output.
I guess my question is this, if I'm reading correctly, do I lose 6db with using this type of connection(XLR-RCA)? I just do not understand why this would be the case? I was almost wondering if there was an issue with my speakerpower amps, since the gain is maxed out to '0' on the plate.
Thanks for any insight!
