One excellent way to improve speaker system synchronization and intelligibility is using signal time delay units. Please remember that these levels will need to be tweaked depending on the source recording and/or surround scheme. Guitars: Electric guitarists generally play a few feet from their stacks, and since the speed of sound in air is roughly a thousand feet per second, each millisecond of delay is equivalent to listening to the sound from a point one foot further away.
