I have been looking for a woofer that will be used in an OB application, in a small baffle, from about 80Hz - 300Hz but definitely not lower in frequency than that. A subwoofer will handle the VLF band.
The B&C 14NDL76 has high sensitivity, a very open basket, and demodulation. The size is a "tweener" at 14inches/359mm so it should have a bit better upper midbass than a 15. Even though the driver would not used "up there" the cone breakup starting at 2kHz seems very well controlled and the response smoothly extends up to about 4kHz before dropping sharply. It's not all that expensive despite its neo motor.I have not seen any measurements but it sounds interesting for my application.
Does anyone have experience with, or know about measurements of, this driver in either the 8 or 4 Ohm version?
TIA
Edit:
Hmm I did find some measurements here:
https://www.justdiyit.com/bc-14ndl76/
When measured at 15cm distance he reported H2 at 2.83V at more than 1% already but 3rd and higher orders are much lower.
He also measured the driver at 1m and distortion comes out much lower??? H2 is 0.55% for example. That's pretty good for such a high sensitivity driver!

Does anyone have first hand experience with this driver?
I am also thinking of using some current feedback to raise the effective Q, which would be helpful in an OB application.
