It’s not about the big watts, Class-D P.A. amps like Crown ect can do that. It’s about the amp being able to come close to doubling it wattage for every halving of impeadance 8, 4, and 2ohms!
The classic massive Mark Levinson ML2 mono blocks at only 25w into 8ohms will sound better into into these speakers than any 10,000w Class-D, because it can double it’s 8ohm wattage all the way down to 1ohm ( 25w 50w 100w 200w). Which means it can "DRIVE" these speakers
Granted it won’t do party levels because after all it’s still only 25w at 8ohms , but it will p**s all over your ice power class-d for sound quality, into these types of speakers.
