I hadn't found the Test Bench test of the Faital 6FE100 - I agree the distortion looks too high, particularly that spike at ~750Hz. Vance Dickason frequently tests pro drivers at 104 dB, so I checked - this one is at 94 dB. I'd cross it off the list.But it has high distortion from what I can see. A bit blurry pictures, maybe someone else can see them more clearly?
I found the test on the Faital Pro 6FE100 here:

It is very popular these days. I have it myself and intended to use it as a midrange driver in a pair of three-way DIY speakers. The only thing I'm thinking about is those nasty breakup frequencies. If it becomes audible or not, even if you use a 24dB filter and set the crossover somewhere between 1900-2500 Hz?

The THD measurements at distance of 20 mm and voltage levels from 4 to 5.6 Volt were carried out with High Pass Filter "on" (4th order Butterworth type, 20 Hz cutoff, HPF4-20). The THD measurements at distance of 315 mm and voltage levels from 2 to 4 Volt were carried out with High Pass Filter...hificompass.com
At least MAB thinks so with another driver that has unpleasant breakup modes, here's a thread about it and how he solves it:

FFLOTSAM (Fabricated From LeftOver Things Studio Active Monitor) Active DSP speakers, for testing a few ideas I had some stuff lying around; a few random Baltic Birch-ply panels, some countertop material, a few cans of partially used brown spray paint, and some not-too clumpy spar varnish (that...audiosciencereview.com
A number of these in a line speaker?
