I ended up marking "poor", not exactly for the stock frequency response, since it is designed to be used with DSP, and the directivity is good, so with EQ it should perform fairly well.
My main reason was the insane tweeter distortion. Given that this is a "pro" speaker, the listening distances will be fairly large compared to domestic setups, and the speaker should be able to get reasonably loud without falling apart.
That tweeter is already falling apart at 86db. Given the intended use case for these speakers, a listening distance of 10-20ft is realistic.
The only other area where this could gain some points would be either sensitivity (not all that high), or bass capability (nope)...
And given the $1000 price... I could get the PRX 908 for that price, and it would blow this out of the water.
So this speaker is pretty poor.
