> There are some drivers large enough that they can withstand this power level indefinitely. The car audio market has some pretty crazy designs.

I wonder how true the claims really are. Rod E. of sound-au.com even questions the claims. I see some cheap "1500" watt RMS 8 ohm speakers for like 150 bucks, might be a good test, plug it into the wall through a variac and turn up the power to the full 1500W and see how long it lasts. I am too lazy to look right now but I am sure someone has tried this and put up a video.

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 they 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.

What power level? 120V on a 15A breaker?

I = V/R and a typical speaker is 8 ohms which does happen to result in 15A at 120V. Interesting.

true, I was speccing a bom for a huge output SET amp, slowly buying bits and pieces during lockdown, then I did a bit of wiring on my house and got a minor shock from the mains, threw out everything realising that such a mistake during the amp build would result in a major headache and lifelong trauma for my wife.

That is an absurd amount of power. Even this guy thinks it's crazy and dangerous:

All you really need is 100 W for a good home HiFi. I have a set of the shorter Magnepan (forget the model) with a decent 100W Sony amp and at mid volume is too loud to comfortably listen to yet sounds very crisp and clear with a sealed 12 inch sub driven by a 150 W amp.
