>>Except, almost all bass on music (forgetting an independant LFE channel at the moment) is mono, meaning that I would theoretically get 3db more bass when both channels are on and playing. In other words, the right channels' bass will ADD to the left channels in real-world music listening.
Ahh, I think that one is easier to answer. You're not just going to get 3dB more bass, you're going to get 3dB more "everything" so there won't be any impact on frequency response, just the difference between a lumpy curve around 82 dB or a lumpy curve around 85 dB
