Round 1 of the war of the monster 10" Midbasses - On Axis FR and Harmonic Distortion.
Ciare NDH 10-3's
Faital Pro 10FH520's
Faital Pro 10FH530's
Faital Pro 10HP1020's
18 Sound 10NW750's
18 Sound 10NDA610's
(plus in the future: vs Beyma 10MC700ND's
The theme here is:
- minimum 3" voice coils (for reduced power compression)
- minimum 400W RMS/AES power handling
- most with flux demodulating rings
- ~4-6mm Xmax.
- Low Distortion
- good clean extension out to 2kHz+
This is Texas, go big or go home (except for pricing, lol, looking to stay under $300 per driver limit). Hoping for good low-distortion performance. Intended frequency range use is about 150-200Hz on the low-end, and 1.0-1.5kHz on the top end.
All Drivers FR superimposed.
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 taken at ~500Hz.

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. I had considered the AE TD10M but @ $460 fully loaded it's too much for this hobbyist, lol. I'm trying to get a hold of a pair of PD.103NR1's as well.
Here is a ZIP file containing all data thus far.
