I have an Onkyo amp system where I have a pair of RT35i's in a separate room on the Speaker B channel.
With this amp, the B-channel has no ability for sound processing.
These RT35i's sound great connected to Speaker Channel A where I can turn the treble down slightly, or, increase the bass slightly. However, they are a little bright on Channel B where I can make no adjustments.
Is there any way to place an external, speaker line level, processing device to be able to adjust the bass or treble for just the B channell output (post amplification). I looked at equalizers, but they all seem to be Pre-amplification.
