Ohms minimum).

so a speaker with a nominal impedance of 6 Ohm has as its minumum
impedance, 4 Ohms? I thought it could go below that at certain frequencies.

I thought not, BICBW.

[1] Some amplifiers exceed this. The older Krells, for example, continue
doubling output power down to to 2 Ohms or even lower.

So the newer Krells might not do this? Cost cutting reasons, or they
don't make them like they used to?

I have only seen the specs for KSA-80s and other Krells of that vintage,
and this is what I recall, so I cannot say anything for more modern Krell
amplifiers. SP says the doubling goes down to 1 Ohm with the KSA-50.
