It will take me quite a while to cut all frames and move on to final assembly, but I'll keep you guys posted...
I think I will start with a control impedance test of all drivers.

Nice! So that’s qnty 50x 10F/8414?
That’s too bad the bezels are not the same for a drop in fit. OTOH, the bezel is round so perhaps quick work with a router and round template or hole cutter.

I've got that part covered 😉. With simple hand tools though. Don't want to heat up any glue etc.
There was a blowout sale on eBay? a year ago on 10F’s with flat sided bezels. They were painted aqua green. I think they were extras from some Thiel speaker design. Would have been perfect and saved you from hacksawing these drivers.

I would put very fine tooth blade on a table saw and slide the work really slowly past the blade; except I know I'd eventually get impatient and push it too fast. But you are the guy who routed all the pieces for your translam cabinets by hand, so I doubt you would have that problem.
That was a compliment… sorry if that wasn’t clear

Quite pleased with the first impedance check of all drivers. Impressed really.
Only 3 of them that don't quite fit this bundle, 2 of those are the ones I got in advance. (the 3 not shown here)
Seeing how I have 56 drivers in total I should be able to make 2 very similar sets of 25 drivers each.
Sorting the drivers so that the 5 drivers in the 5 groups averaged out closer to each other did result in a smoother overall impedance for me.
@fluid, I remembered that. I mainly ran impedance checks to see if all drivers were healthy. That was my first priority. But I saved them to be able to group them like you did.
@b_force not using a real crossover but a low shelf at 160 Hz. After first eq-ing the response flat, down to about 20-30 Hz. Max boost was about 14 dB, low shelf was -9 dB, so final max boost left was about 5 dB. Here and there the array helps the sub and vice versa.
Will see if that game plan still works with these drivers. Overall distortion will show me what these can take vs the TC9.

mmm if you wanna improve the overall sound, I would definitely recommend just using a 150-200Hz highpass filter on there, and just a couple of (stereo) subs.
Even with 25 drivers, de low end on these things isn't extremely great plus there is a lot more possible with a couple of subs.
Using any speaker way beneath their Fs is not really recommended, the compliance can do some very weird stuff there.
