Wayne sent me a pair last week. I mated them with the DE250 and using a variation of Wayne's crossover, same filter, more typical resistor L-pad and sometimes a 4Khz 3DB notch using 4ohm resistor, .15mh choke and 10uf cap.
Sound stage and image are very nice (unobtainable with a dome). The tighter pattern works very well in my so-so room. Smooth and very listenable even with clean rock-n-roll guitar where some horns get "in your face". Sibalence and SSSing are very well controled even on Diana Krall vocals (where the 4K notch helps).
I've been using 15" two ways since the mid 90s and this one's the best. AE TD15S woofer for 93db to 24hz. I cooked up my own 3rd order lowpass to meet the horn.
Jazz and contemporary fans might not want the notch but for me and rock-n-roll it's what I perfer. YMMV
