Looking for some advice from the experts here. I have a RX-A3000 for my home theater setup and just finished filling out my speakers for a 7.1 setup with the following:\nFront L\/R: Klipsch RP-260F\nCenter: RP-450C\nSurround L\/R: RP-502S\nSurround Back L\/R: RP-500SA\nThe issue that I'm running into is significantly lower output on the surround back speaker channels. For testing, I have the receiver set to 7ch stereo and the following levels\/distances from YPAO:\nSL: 0dB, 9ft\nSR: -2dB, 5.6ft\nSBL: +0.5dB, 9.8ft\nSBR: -0.5db, 9.4ft\nAll speakers are set to small with a 80Hz crossover. Power amp is set to 7ch normal and bi-amp is turned off.\nAudibly, I can hear output from the SB speakers but at a very reduced level and if I lightly touch the rubber surrounds on the speaker itself there is a large difference in how much the woofers are being driven when compared to the surround side speakers. I did swap the speaker wire inputs on the receiver for the SR and SBR which then caused my SR speakers to be at a reduced level while the SBR were now good, so it's not a speaker issue. I don't think I'm trying to ask too much out of the receiver with this setup, but would appreciate any input. Do I just have two bad channels? Let me know if there's any other config\/settings that I should add.
