Yes, it looks much smoother, the ~3k notch has become a mere depression with the phase reversal between mid & tweeter. But there's that 4K spike, it looks bad, doesn't it? Must be approx 5 dB. And it's a narrow Q. If I moved the tweeter front/back slightly, do you think that spike would move or be cut? If I had the speakers home, I'd try that right now. So I'll play with the tweeter positioning, I should be able to move it a few inches without getting into reflections off the top -- at that wavelength were talking short -- and try to get the best notch and see what happens to the spike.

Oh wow, I realized ur editing ur post as I type, so I'll hold off a while until the final version...
