Ran across this demo on youtube....went to check out his site, and his amps are certainly cool looking!

They certainly look cool! Probably insanely expensive...but just wondered if any of you have seen/tried one in person?

Slightly OT question about the cabs. 3 speakers? I saw an old Peavey 3x12 cab once, and I've seen Vintage Club combos that were 3x10s?, and every time i see something like that, I wonder, how does that work?

3 4 ohm speakers in series, 3 times 4 = 12 ohms

3 16 ohm speakers in parallel, 16 divided by 3 = 5.33 ohms

Are they some bastard size speaker that isn't 4, 8, or 16 ohms, or do they use normal speakers, and the ohms are "close enough"?

2 - 4 ohm speakers in series (8 ohms)

then wired in parallel with an 8 ohm speaker = 4 ohms

However, if the different speakers have a different impedance, the lower impedance load will have more power delivered to it. Its a good idea to make certain that any given driver can handle the power you plan to apply to it.

They also make this model:

Here are the specs from their site:

 

Though rectangular in shape, the Switchback 312 utilizes an internal triangular chamber to house three 12-inch Celestion Vintage 30 speakers, attaining the same output volume as typical 4x12 designs in a cabinet that
