I don't know where you got this from, but flush baffles are used very often without problem. Internal to the tweeter (and thus in an area we cannot see or sometimes it just isn't noticed) there can be a waveguide which allows for proper dispersion characteristics without need for baffle compensation allowing for a flush mount with no problems.

If DS-21's reference to a 180 degree waveguide is where this came from I believe he was referring to a situation where a non-waveguided tweeter is used in conjunction with a flat baffle which is exactly what I plan on doing and as I have previously said is an extremely good idea if proper methodology is taken .

Baffle compensation is only really needed in the case where a non-waveguided tweeter is used and the tweeter in question has extremely linear off-axis response. If the compensation is not taken off-axis response will be ruined due to wave diffraction issues.
Yes... I was referring to his comments... (A flush baffle is just a 180deg waveguide.) and A 180deg waveguide is basically hopeless, and leads to all kinds of problems in the midband power response, because it does not control the dispersion of the tweeter at the bottom of its passband at all.

I am not aware of any credible 3rd party measurements on the Ascent I's. If you know of any I could give you my thoughts on the objective performance of the loudspeaker. If you wish not to jack this thread feel free to PM me or start another thread.
I am not aware of any either. I really haven't even studied the ML philosophy for that matter. I just can't get over how much I like the sound... even if someone discovers they are design flawed. In that case I would say I am glad they erred.
