IIRC, the M2 stock amp DSP includes some flattening EQ, not just cross-over EQ and delay. EQ settings are in the amplifier configuration file for the M2.
As already said by ticknpop (Mr. Agitator please read the replies to your agitations), series and parallel connection of the floating outputs can provide a good selection from a combination of DC voltages and huge current capabilities (plus there are modules up to 1500W each).

Almost Damir... I posted in your thread schematics, each amp channel needs two Class-D units, each one are offsetted positively and negatively respectively.
200W Class A amp with high efficency
If Class D amp is used instead of variable switching power supply one is enough per channel. I hope I will test my design this winter, hopefully.🙂

I am sure they did a really nice x-over job of getting a flat response, GD, phase, etal at 1 Meter test in echo free chamber.
Shown is the same speaker(s) but no EQ for room corrections..... you know, peaks and dips/nulls from reflections etc etc of the room.
Which points out the benefit of more narrow dispersion and CD (constant Directivity)

No room corrections, but yes to some speaker frequency response corrections.
That's okay, of course. Nice product, although a little slow to find its way into mixing and mastering rooms.
Have to wonder if the amp with it's built-in DAC is fully satisfactory to some customers.

Yes. But as you know, flat response doesnt usually stay that way in a room environment.... because of the CD and more narrow dispersion, the flat response is maintained all the way to the listener.
No room/speaker corrections/EQ needed.

I can think of some exceptions! 😉
Personally I think there is a chance all JBL may become classic unobtanium.
Currently looking at a project 2 years down the road with a minimum design life of 8 years. Crown now in Mexico has an issue with not enough capacity to rework units that fail final QC. So parts in to devices out yield is way wrong, leading to shortages.
New structure is Crown folks relocated to Texas, specify the design, an engineering group in China designs it for manufacture in Mexico. What could go wrong?
Jbl fired 3/4 of their engineers. A great boost in productivity no doubt.
Would anyone bet on the on time delivery and reliability of their products?
I did order a replacement diaphragm in February, got delivered in October.
Worse yet the specified product is one I had a bit if design input to it.
Dang, Simon, that ain't exactly a list of fun facts.
I didn't realize there was that much stuff failing final QC these days, percentage-wise.
QC is in China.
No, professional division (BSS, dbx, Lexicon, DigiTech). No profit in two years. You may start search for another vendor.
It should be noted that companies can have design and production all around the world and still retain quality. It's just hard and requires good leadership. It's just when companies sub out purely on cost that bad things can happen. We can but hope this is a minor glitch.
