Thanks for the suggestion. I tried them out further into the room, the sound wan little changed, measurement showed about the same - 3dB point of 16 Hz. It's possible I could have gotten more SPL out of them further in the room, but in their current position I can easily get my 95 dB overall system SPL goal.
In addition to affording a much steeper crossover slope, the DEQX corrects for things like group delay and so on, I've tried without it and the sound was not nearly as good.
