How do you know your left surround is to hot? The room characteristics and speaker placement play a huge role in the end results. My right surround is 2 dB's different than my left surround, because my right surround has no wall behind to reinforce things.

The sub distance can somtimes be different based on internal delay in the sub amp circuitry, especially in DSP subs. However, normally the setup has it further away than the physical distance.
