Doing some testing on 10" midbasses for a future project. Going for: high-efficiency 10" midbasses pro-audio style, with low distortion. Nothing less than 400W RMS/AES/super-heavy-duty whatever you wanna call it, no less than ~4-6mm Xmax, nice extension out to 2khz+, no smaller than 3" coils, flux demodulation rings if possible, under ~$300ea. Goal is midbass duty in a small sealed box (~0.5 ft³) from about 80Hz up to about 1.5kHz (depending on other factors of course).
Contenders so far:
Ciare NDH 10-3 (no FD)
Faital Pro 10FH520 (FD)
Faital Pro 10FH530 (FD)
Eighteen Sound 10NW750 (FD) (on the way)
Beyma 10MC700ND (FD) (ETA September)
B&C 10PLB76 (FD) (ETA June-July)
and just maybe might consider the Eighteensound 10NDA610 (A.I.C. (Active Impedance Control)) even though it doesn't fit my "requirements", but it looks damn intriguing. 2nd Runner-up's also considering: B&C 10MBX64, Beyma 10MC500, Eighteen Sound 10MB600. I looked at RCF but can't say that any of their 10's piqued my interest. Eminence looks bland compared to these babies.
I already did some preliminary testing on the Ciare that I received first, but still more testing to be done. Here I am testing it along with some AMT's (Hygeia/Airborne, Dayton Audio, Beyma).
Stay tuned. If ya want

As expected from the FR graphs, the 10HP1020 is the "dullest" and the NDH10-3 is the "brightest" sounding. The funny thing is, all the Faital's and the 18 Sound drivers have demodulating rings in the motors, and Ciare says that the NDH10-3 does not have any kind of shorting/demodulating rings in the motor!.
Individual driver distortion performances. SPL levels at the specified 105-107 dB are @ 1m on-axis.

This last graph shows the THD of the 5 above midbasses superimposed into one chart, with the very last one being windowed from 80Hz-10kHz, from 0 to 4 % THD.
Next time I'll do some CSD plots and polar response plots. Maybe with some more midbasses.
