I do not agree to the core of this article. The V/I limiter doesnot switch off the current, but softly limits it to a preset value. There is no voltage spike as a result. The spike could only occur if the current is abrubtly cut off, but that is not the case.

LaughingDragon, you can *measure * the speaker impedance by putting a defined DC current into it and then check the DC voltage with a comparator to a preset voltage. Only switch on the relay if the comparator says it's OK.

Diode on output? Regardless horrible distortion it should also be avoided from following reason: when diode switches off (near zero) it will produce transient spikes at crossover speaker circuit.
