Part of my job is servicing & repairing PA systems, and I recently encountered some Pascal modules in K-array subwoofers (the X-PRO3 module). K-Array usually use the PowerSoft OEM modules (which are excellent), so being given a dead active subwoofer to repair that had a Pascal module in I suspected the Pascal....
Turns out the sub was so powerful it could vibrate its own ribbon cables off the boards! They should have been secured better for the application. So, for subwoofers at least, I would highly rate Pascal components. Clean, efficient and reliable power.

i make 2 Screenshots
from the Power Extension PDF s-pro 2.
I think it's very interesting with the Power Extension but I don't know how exactly to produce them. There are no finished ones to buy.

I think you can get finished boards from connex electronics (not made with same connectors but should be compatible) . For class d low esr is important.
