Here's the manual, but it doesn't seem to be much help. I would set the controls at their midway points for starters.
Thanks for link. I'll take your advice and see how it sounds at 1/2 way.
I've been playing them at what I'm assuming is ~1/4 of the way and they sound great.
These speakers are much nicer...I was using a pair of Polk RT800's and the difference in sound is amazing. I'm now hooked on quality speakers.
