@woodsage Actually these are the BD-Design Orphean-220 horns utilizing the new Celestion AXi-2050 driver. The amplifier for the BD-Design compact reference base enclosures is a Crown XLS-1500. Both amplifiers utilize minidsp as the xover.
I do have in addition a pair of Oris-150 horns utilizing the Voxativ AC-2.6 8" full range driver. I have used Lowther and AER in the past and found that the Voxativ to be superior in my listening room. I am happy to sell the Oris system if anyone is interested as well as the Coincident Frankenstein 300B monoblocks that are the perfect match for these speakers.
