For 2 channel stereo I use a pair of Cornwalls placed in the corners at about 15-18' spacing. With my listening chair in the correct spot, it sounds great to my ears. I have a pair of Heresy's not being used and I like to listen to mono records in that same listening space.
Can any suggest how I should place the Heresy's for mono playback?
p.s.- I never experimented listening in mono with my current setup with the Cornwalls.
