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
its really difficult to say so remotely without knowing both your
piece ans the place. but generally i'd say: don't use too high
volumes and use good sounds for the room you're in. "natural"
reverberation can be used or played with very nicely and ear-
pleasing. but the higher volume goes, the more the room gets excited
and filled with echo and reverberation and the "uglier" it sounds to
the normal listener...
