** Polyswitches are not a good alternative to low voltage lamps with horn drivers in systems used for sound reinforcement.

Biggest problem is the sudden switch off of the horn and long wait for it to come back on - this is unacceptable to performers or audiences.

OTOH, correctly chosen lamps act immediately - reducing the over power condition to a safe level for the horn driver and then recover almost as fast.

Many active systems use limiters that do the same job.
