Sorry for the late answer. Have been travelling.
Thank you for the link. That of course is a different take altogether. Nice work.
Yes, you understood correctly on the amps.
But I do understand your dilemma with the NL8. Only if you made a change to an ASP.3 like setup would that work. In the end you/he will run out of excursion on the woofers first in most cases 😆
Wish you fun with the final stint 👍

Yeah, that appears the case. The xmax of the SLS is 10.9mm, while the RSS265HF is 12.3mm. Not clear whether that's one-way or the whole range, hopefully the former. It can also handle way more power.
The SBA 10" is 22mm total xmax; Scan-Speak 10" sub is 25mm; the SEAS L26Y hits 30mm, tho -2dB less sensitive than the SS 26W/4558T00, which seems like a sweet spot: At Solen, CA$460. Pricey but not as bad as $750 for the SEAS. Will have to try them for my main studio speakers when I'm feeling flush.
This seems wrong. RSS265HF-8 is actually rated for 14.3mm xmax, which makes me a bit more optimistic.
I love these modules. Powerful and so easy to implement.
Can someone advise in how to get a power on indicator (led) to the front panel of the chassi?
Thanx!

I did not try and check the max excursion in WinISD, but I would not be surprised if you are still able to reach full excursion on all units with the 2x300w at hand - with low end content in the 20-30Hz range. Given that this is still an OB system.
That is just the nature of the physics - not that it's a problem 🙂
Let me know if I misunderstood your question and it is about a specific Chassis or the approach in general:
If you are using one of the buffer modules anyway - then the quick and dirty approach is simply to duplicate the LED's on the buffer board.
You could of course also just have s simple pwr on indication by using the +/-15V pads to connect to an LED with appropiate series resistor.
Quick head calculation 10-15kOhm could be a starting point.
But for the "lazy" I found this: https://www.digikey.dk/en/resources/conversion-calculators/conversion-calculator-led-series-resistor
If you look up the Pascal S-PRO2 or S-A2 add on board documentation - you will find the description of the identical 26pin board connection, where all interfaces including signal / status outputs are described.

Did this ST version get completed, read though the thread and didn't see any more mentions of it? Thanks
Hey man, the ST means stereo or two channel model. That's the regular FFAxxx series. The H/B is the variant where one channel is set for more power than the other and best for a two-way active speaker with the H/B module fitted into the speaker box. The regular stereo boards suitcase mounting and sound bars and such where you don't need to send off a speaker wire to the other speaker
The power rating of this 2*250W was covered by our 2*300W(FFA002V2) module, and we just built one prototype and did not proceed the future development, and that's why we did not publish it in the thread.
And you can try our 2*300W module if this meets your application.
Thanks,
Eric
