….does this mean they are rated to take a speaker load as low as 2 ohms? Sorry I’m a slow learner and still trying to get my head around speaker matching/amp loads.

IF the incoming wall power doesn't sag, and IF it's for a short time duration, and likely IF the crest ratio is large.  Hence why I don't design systems to run at 2 ohms, regardless of the amp.  Especially for lower grade amps like PLX.

ETA - thank you for pointing out the typo, Art!

Preach it, Brother!

The road to audio hell is paved with poor electrical service and operational methods that put extra stress on all system components.

If the crest factor ratio is low, the demands on the amplifier are highest- a square wave is 1/1, or 0db, a sine wave has a 3dB crest factor, most music is in the 12 to 20dB range.

Low frequency often has the lowest crest factor ratio, followed by mid (what the OP planning to run at <4 ohms) followed by high frequency with the highest crest factor ratios.
