Here is an example of what I am referring to:

These competition grade units would probably trip your breaker before they burn up.

Indeed. Those dual 1 or 2 ohm coils, even in series, would pull 30 and 60 amps respectively at 120 VAC. You could feed it from a two pole 60 or 125 amp breaker though at 1 ohm it would pull 14400 W and likely not last very long.

I still would still like to see how long a so called 8 ohm 1500W speaker will survive on 100-120 VAC mains.
