A guy here sent me 4 of these to play with so I baseline tested all 4, compared them against each other, then did the full testing on the better of the 4 samples.
The one thing I will say is that 3 of the 4 perform really bad in terms of HD. The one I wound up doing further testing on looked much better but still wasn't great.
The FR on these rises +10dB from 1khz to 3khz and winds up at +18dB from 1khz to about 8khz. Off-axis response on the horizontal axis looks pretty good with some issues above 5khz. CSD shows ringing around 6khz which shows up in every FR measurement as well. Vertical off-axis response is bad but I've yet to see a ribbon/planar that isn't bad vertically. (bad meaning no controlled dispersion... just wonky).
HD isn't too bad; some spots here and there may be of concern but nothing terrible and overall 3rd is pretty low (minus the peaky spots). *Now, if you look at the comparison HD plots, it's an entirely different ballgame and the HD is so high/sporadic that it's just scary.*
Crossed from 300-2khz seems to be where I'd be expecting to land - if I were using them in my own setup - given the upward swing in response and the poor vertical dispersion off-axis.
