Vertical vs Horizontal Bi-amp

I think another benefit, if you're using identical amps, may come from the fact in horizontal biamp the bass amp will need to drive more current than amps running in vertical biamp. The work required of the power supply is balanced - again amplifier dependent as well as speaker dependent.

Bd-nice thoughts!

In my rig vertical slays horizonal. No contest. But it's a totally different approach of course.
