Of the surround sound speakers, it always seems in my setup that the rear most speakers are dominant compared to the immediate R&L surround speakers, even if the speakers are all the same brand and model. Is this typical? Or do I need to go back and tweak the calibration settings for the R&L surrounds and boost them? Curiously during the speaker calibration via the AVR, the test tones from all of the surround speakers are at the same volume level. Or another spin on this is that the immediate R&L surrounds are the least important speakers in a 7.1 home theater system and it may not be advisable to spend much on them.
Hi! Has this been resolved or your problem remains? I just want to share that I have the same problem and when I called the Oppo Technical Support, he said there is no known issue like this. On my previous test, I still had my Oppo 981 so I was able to compare the exact same settings except of course the trim as 980 has 7.1 and the delay which is in feet for Oppo980 and in inches for Oppo 981. Also in 980, it is the actual distance while in 981 it uses the difference between the Front Left/Right to the Center, SL ,SW and SR. Anyway, I have the same issue so I think there must be a technical problem that was missed by Oppo.
