I'm sure you you will some answers from the more set-up experience people here, but as a gym goer I'm glad you're keeping the speakers in pairs, and not having 1 speaker by itself be in one location , playing just the left channel, and another speaker clear over in another room, playing the right channel. I used to go to a gym in Wichita that did that, and every time some music would play that would have a guitar riff play in one channel and then have something else play in the other channel, it sounded weird. I remember hearing just the right channel of Back in Black and the end phrase to the riff was always missing, since it was playing in another room!
