I've been using 2226's with Great Plains Audio 399's for some time. I recently acquired some very nice Apollo cabinets. The Apollo cabs have an internal volume of roughly 3.2 cubic feet so they should be a nice match for the 2226.
I have 500hz Edgarhorns and my crossover is at 1.6Khz.
I plan to elevate the Apollo's about 6 more inches to get the Edgarhorns at ear level and simultaneously get the 2226's further from the floor.
I really don't need any advice (though it is welcome) or feedback, I just wanted to share a few pics with you all.
Oh yes, many thanks to Ron (Speakerman) who pushed, nagged and cajoled me this way from a Dual concentric world.
