  Another try with 2nd order HP LP for 811B/D250P-8 and 55-1220. As suggested below, set target Hz HP LP response curves in ARTA. I have a limited supply of inductors, so caps were adjusted until the target acoustic response was measured from my listening position. I set the horn back about 3" on the cabinet, but that didn't seem to do anything. The effects of compensation can be seen on the sweep graph. A work in progress, as usual.
