class AB 10.000W RMS @0.5R - 20.000W rms bridged

The best way to do it is the way the pros do it. With four amplifiers. Eight four ohm cabs is half an ohm. And eight #12 extension cords works quite well for speaker wires (with an "s"). It's a better and cheaper solution assuming you're driving 16 drivers.

.5R is completely pointless, is just a matter of heat dissipation because of the humongous demand of current(And a very expensive undertaking), as stated before i think this design works in real life, but not into .5R, even at 1R there will be lots of heat to deal with, needless to say the AC supply for such demand, you will need a power station of the electric company just for the amp itself, capacitor bank should pose a problem, as well as bridge rectifiers, along with weight of the complete set up, quite impractical in real world, again, for .5R and 1R but *The Thing* can manage 8, 4 or even 2R loads with ease.

An externally hosted image should be here but it was not working when we last tested it.

the pics are no longer available.

btw why are all engineers here wondering, and before class d became famous , in the late 90,s car amps used to support 1 and 2ohms loads and they were class ab with big heatsink as casing and no fans ;,. 😎 😀 😉

10.000W / 230V=43 A. Sorry can't test it. I have just 3* 20A at home. I have to hire a generator.
