What do you guys think of this combo? The 4648 would run from 40-200hz, and the 4560 would do about 200-1khz, then crossed to a cd/horn. The 4560 has a weird curve that is most efficient from 200hz+ but extends down to 100hz and then drops like a rock. I have 6 of the 2226 so that would go in all 4 units.
