Dave, I have nothing helpful to offer, but wanted to thank and congratulate you for doing a great job with analysis and documentation. I think your journey will really help other people.

Even if you chose the wrong mains. \:\)

I had a similar occurrence with Audyssey and the QS8's (a pretty high xover point). Weird.

Will you be using the Ceiling FMB for the QS8's? My inclination would be to use that method AND to angle them a bit.

Have a fun weekend!
