Larry, curious about your results. I have the BA 9000II setup as well, and I haven't noticed the sub wandering when the LFE of the sub is connected and the L/R binding posts on the sub are connected to the LF and RF, speakers, respectively.

Could it be something on your test DVD? Did you get the same results using the 1050 test mode? How about when you play DVD's, would you notice a "wandering"?

I haven't fiddled with it much since initial setup , been too busy enjoying the DVDs. Still, there's always room for improvement.... might want to play around a bit to see if I could recreate your problem.

Cheers, UW
