At app. 2' from the front wall of the room I started the bass reinforcement/imaging trade-off. My old room was large and the VSMs were SEs so I settled on 2' for max bass with decent imaging. Subsequent rooms were somewhat smaller (current is app 14' X 19') and the speaker/BAM have been upgraded to produce significantly more bass. I'm now at app 4' from the wall - imaging is much improved (about as good as any speaker I've heard) and bass response is full, powerful, and very nicely balanced.
Good Luck,
Marty
