Since I had my IB test baffle out, I measured the ND25FW. Same 1/2 meter test conditions as the measurements I took on the Scanspeak and Vifa drivers:
Honest! That is 1/24th octave smoothing! The 2nd harmonic and THD spike is right at Fs (no surprise). I'd say with a LR4 slope 2kHz should be doable. Hard to believe this was a only $13 on sale tweeter.

Dayton is so polarized. Its all or nothing with them! Great tweet!
I just took the in box measurements for my ND25FW and MCM 55-2669 MTM project. The measured responses were super easy to filter just as predicted. I've already sim'd up a nice looking xo that only requires 7 parts...
I'm listening to the prototype xo's now... really nice right out of the design box. A small tweek to the tweeter padding maybe. I like this tweeter a lot. If they go on sale again I'll definitely pick up another pair.
These are very solid MTM's but honestly they still need a sub to play that last octave. I have plenty of time to finish their voicing and finish their appearance before InDIYana. Impressive speakers for $78 worth of drivers and only modest xo parts.
