I would ask if anyone knows of resources to look at for dealing with these kinds of issues? How are other artists sorting these things out? Any links or recommendations would be very helpful. Low ends tend to get very muddy and the highs and mids spill all over the place. Are there certain tricks I could use in mixing or placement/kinds of speakers to preserve the highs and mids better in a difficult space? This might be a difficult question since you can't hear the piece in person, but even general advice would be very helpful.
