TH-18 Flat to 35hz! (Xoc1's design)

I put my Inuke 6000 on a CRO, and observed that the quoted power is PEAK, not rms. So id call it about 2000w @4 ohms, theoretical.
I say theoretical as I dont believe they can sustain that power.....there is very little reserve capacitance in the inukes.
When running off a generator at high demand they sounded like they ran out of puff on each kick...a little floppy/distorted. And the lights would dip too.
The Inukes have no PFC correction, they take a lot more current than it´s nornaly needed for the output power.
If the lights dips , probably the voltage from the generator drops to much.
Inuke at 2000 real watts on 4 ohm is about right. +/-80V supply, full bridge, maybe 80% supply regulation. That gives 2k per channel into 4. Assuming of course the mains stay at 120V. It can actuslly sustain that for a while, but it’s not goof for it. A lot of infant mortality fails due to THERMAL CYCLING. Run ‘em for a year, get something better if you can.
If the lights were dimming, the generator (or AC cables..) were not providing enough voltage/power to sustain the peak demands, the system was "undersized".
The generator at minimum should be capable of around 7000 watts per Inuke 6000 to keep up with their peak demands, not including any lighting loads. The cabling should be sized to not drop more than 5% at the peak draw.
The amplifiers with the best PFC could reduce peak demands by ~40%, which could reduce the generator size.

Since this gets asked about once a month, I'll summarise :
It has been stated a number of times that there are no published mk 2 plans. There are little hints here and there about changes / improvements, but no new drawing (that has been made public anyway).
There can't be a single drawing that covers all possibilities for the cone correction anyway (what people seem to want when they ask about mk 2) since a different design would be required for each different driver.
