Power handling specification is mostly meaningless, particularly when there is no standardization in how its reported. Most of y'all listen at less than 5 Wrms 95% of the time, substantially less if the speakers are particularly sensitive/efficient.
People plug giant car subs into AC mains as a torture test. I have my doubts that nearly any home speaker would survive very long unless there is an impedance peak near 60hz.
This is a giant dual voice coil car sub taking the AC treatment. Very low impedance driver so huge current/power.
