Yes, but if most low impedance speakers remain in a "workable impedance range" if I can say that, the amp will work flawlessly. For example, if the speaker in operation stayed close to its nominal impedance, there would be no heating issue for the amp rated to work at that impedance.

If the speaker "worked" but its impedance dropped below the amp's rated operational limit, the amp would run hotter and potentially trip the thermal protection circuit.

There has to be an explanation. I guess I am having a hard time understanding where the problem was. I can only think that the speaker may be faulty as far as the Outlaw amp sees it but not a problem as far as the Parasound amp sees it.

The Anthem amps can take a fork across the leads with no damage. Of course the protection circuitry kicks in but the point is that some amps handle lower impedance loads better than others. I know, not the best example - I don't have a pair of forks for my mains speakers so I don't need an amp that can drive forks. Nor do I want to pay the 3x price tag of the Anthem compared to the Outlaw.

Am I making any sense?
