Not trying to hijack the thread, but I bought a pair of 926s about 2 months ago as well. I still, to this date, am not able to dial them in to sound solid. I know they can sound great but I get this boominess I can't get rid of.
Driving them with Hegel H390 and recently introduced KEF KC92 sub (which I had with my KEF LS50 Meta system), which helped a little BIT, but still some songs sound boomy.
I am at max where I can pull them away from walls. I'm sitting about 12 feet away. They are about 10 feet apart toed in (good idea?) and about 1 foot away from back wall. My room is 16'x20'x13' ceilings.
Any help would be appreciated.
