Rusty, did you ever get a chance to play with the Rolls crossover?

I've ended up with a quasi minidsp-type fix.

The solution was hiding in an upstairs closet. A DBX Driverack PA was originally purchased 15 or 20 years back to try room correction but I wasn't happy with the results. It was being run full range and seemed to rob a lot of the magic from the tube system at the time. It went into the "sell it" pile and I hadn't thought of the thing in years.

Pulled the Driverack out of exile and added a volume control and a Texas Instruments TPA3255 class d amp. The TI amp is far superior to the old plate amp and the front subs are now in stereo. The bass is cleaner and now has far better texture. I was hoping the sonic shortcomings of the Driverack wouldn't be an issue if it was just being used for the low frequencies and it seems quite fine doing just that.

"Best" settings are still a work in progress but it's sounding great.
