I recently purchased an Onkyo TX SR603X and Polk RM6800 speakers. The salesman told me I would need a subwoofer cable, so I purchased that.
FYI: The Onkyo auto setup sets number of speakers and their size, speaker distance, crossover, speaker level calibration, and equalizer settings.
My initial setup was to use the receiver’s subwoofer output jack and cable to the left RCA input on the subwoofer and ran auto-setup to setup my speaker’s levels which set subwoofer to on, and the front and backs to small.
Then I read the manual and two white papers on this site on bass management and so ran more speaker wire and followed the “strongly” “Recommended Setup A” (both front speaker line outputs to the subwoofer inputs, and subwoofer outputs to the speakers) and again ran the receivers auto-setup which set subwoofer to off, fronts to large, backs to small, etc. When I listen to action DVD’s with this setup I get little bass compared to the “rumble” I get using the sub-woofer output and cable.
Did I do something wrong? Does it matter that I set the volume control on the subwoofer to its “mid” setting. Is this something with the Onkyo’s setup program that I should override?
