Wicked!!! What plate amps are those ? Sanway? 86sound?To give a quick update:
No new measurements extra as of yet due to not having a working RS485 adapter...
However, did finish up the cabs with amp modules:
Each sub (4 in total) have to extra channels which can power some tops. Being it Sub+Top, Sub+Sub+top or a 2.1 setup, no problem.
Sound is good, go low and still sound tight and behaved.
I believe that nowadays ported bin can excel in SPL density for compact boxes. Compared to the sealed box, the port positively adjusts cone excursion, impedance, provides some cooling, allows for deeper bass or more SPL in that region.
Same thing if bass extension is taken into account. In a small box, a waveguide is not able to couple the air to the speaker at low frequencies, so it is inefficient.
Of course one can generalize too much, and I am already talking about niche approach. But it works. But in the volume of some smaller THAM/Cubo and other designs, you can already high excursion 18"-21" mofo speakers, and that's no match below ~45Hz.

Well it does not cost 900 dollars around here
. Aroudn 525 dollars if you buy 4.Its from OMB audio, you can find them on alibaba, aliexpress etc.
I made the grills with help from a friend he has a (if I translated it correctly) a manual press brake (kantbank/zetbank in Dutch). Its just a perforated sheet of 1.5mm thich with 90 degree sides.
Its indeed the 4 channel one PFA8000. Also looking at doing something with the PFA3002 (or two).
Thanks! They are the EXACT design and mounting scheme I have planned for mine. It's literally the last step before I can finish them.
No Ethernet on those amps?
U can use one of this

Or this
If you prefer USB

Hope OMB adapter works, sound like bad ports on the plate amps, but it is kind of strange that all of them do not work.
Sometimes a batch got defective.
Also, do you plan to do some freq response tests when you adjust the DSP? So to compare HR sims vs real life.
Keep us updated, I am eager to find out what will be your final DSP settings.
