The music sounds different depending on where one sits in the hall. While demonstrating speakers I watch the listener's physical reaction. If they are a rear hall person and I play a bright speaker the listener will pull back slightly because the rear hall sound is more mellow. The inverse is the front hall person who will lean into the sound if I play a mellow speaker.

Someone who regularly plays in an orchestra tends to want a bright speaker that will emphasize the close-up working sounds of the instruments. These sounds are related to technique and this is very interesting to this class of listener. These listeners tend to prefer close miked recordings too.
