Hey folks. Finally got my first non-HTIB surround sound setup hooked up yesterday. RTI A1 fronts, CSI A4 center, FXI A4 surrounds, PSW 111 sub, and Onkyo TX-SR607 a/v receiver. Now on with my question. After getting everything set up, I tried to run the audyssey auto cal and am getting the speaker error after testing the subwoofer. The woofer is connected via RCA SUB out to Right Line/LFE in. I have to turn the volume almost all the way up to get minimal bass response from the sub. What's going on here?
