I'm not selling anything and this ain't spam. I just came across this and thought it was pretty nuts thought some of you might want to see it. It can be yours for a mere $25,000.00 USD but you will need two so you might want to bring $50,000.00 and a Ryder truck with a lift gate. They are the size of a closet and will heat your house like a pot belly stove but think of all the bragging rights you will have. It's like a whole jigiwatt of pure tubalisious power. I have no idea what they would sound like but I'm pretty sure two of these could power the next Oz Fest.

The $25,000 cost probably is the shipping. They want it out of the warehouse to make space for things they can move (in both senses of the word).
Considering it would be for mid-range only in view of the frequency response, which amp would one use for bass?
30 Hz is low enough for anything that can handle that kind of power. Think four 21SW152’s. Horn loaded, of course.
You NEED a 10KW dummy-load to safely work it at 10KW output. Then you may get 20KW heat between amplifier and dummy load. That's ~~65BTH/h. Which around here is not a large house furnace. And any fool can push a pot-belly stove harder than that. Ask the fire dept.
For a little more resistor money and a LOT less amplifier money (and shipping!) you can get a 20KW dummy load. Look for "electric baseboard", although you can also find electric furnaces for the house.
68,242 BTU 2 - 3.5 Ton Mobile Home Electric Furnace with ECM Blower Motor $1500
20 kW worth of heat strips barely puts a dent in the heat load when it’s less than 20 degrees outside. Might get it to 55 in the living room, and we’d be freezing our ***** off. Propane furnace does just fine.
A couple water heater elements works as a dummy load. Water required. Keep adding ice.

I did get a call from them once. They were looking for an amplifier to test circuit breakers. Foolishly I told them the right way to do it.
May want insulation? 20KW is like 68,240 BTU/h. In my 1,400sf saltbox, my 42,000 BTU furnace will hold 65F inside for -5F outside, and 69F whenever it is above zero F. (And the 42k BTU rating is probably Input; but at >94% efficiency that makes small difference.)
First things you’ll have to do is replace the selenium rectifiers and recap.. Sounds like a fun weekend lol.
This thing might have oil caps and only need to eject the selenium rectifiers.
I have a large Wurlitzer organ that had a large selenium rectifier for the low voltage stop controls.
The thing started smelling a little and I knew the rectifier had to go. Quickly replaced with a bridge of some sort.
