The alternative is to own amps that will drive anything. I was lucky enough to buy several Class A amps that were stable into 1 ohm loads early in my audio hobby - a pair were driving the heck out of Apogee Scintillas at 1 ohm setting.
We should reject hard-to-drive speakers more often
Sorry I know this is a bit of a rant, but come on people!!
Too many audiophiles find speakers which are hard to drive and... stick with them!
We need to reject hard-to-drive speakers as being Hi-Fi. Too many of us want our speakers to be as demanding as we are with a glass of wine. "Oh, this speaker sounds great with any amplifier, but this one needs amps that weigh more than my car, so these speakers MUST sound better..."
Speakers which may be discerning of amplifier current delivery are not necessarily any good at all at playing actual music.
That is all.
