Especially because there's a fair amount of energy in most program material in that region. That could get dicey without a surprisingly beefy amp.View attachment 409706
Seriously now, an EPDR lower than 2 Ohm between 80 and 800 Hz isn't really an easy load for many middle class amps.
Most are rail switching/tracking AB, so I'm going to guess it still has some relevance.Thanks. Begs the question : What about class G and H then?
