I’ve had my Legacy Calibres since Sept ’17, and while I have not heard the Harbeth’s, I can say that these Calibres are monsters! The sensitivity rating is typically an in-room measurement, so it may vary a little bit, but based on other speaker’s I’ve owned, they seem more on par to a 86-87 dB/2.83V/1m kind of speaker system. The bass capability and resolution is nothing short of stellar.
But what they may lack in some sensitivity they make up with with a S*&^load of power handling. I don’t listen to jazz/light classical/ or other wussy crap. I listen to Napalm Death, Carcass, Slayer, Emperor, Sepultura, Morbid Angel, Suffocation, and other cool bands :) at EAR-SPLITTING SPL levels and massive solid-state amplification, and they take the abuse and punishment like no one’s business. I use a total of THREE PEAVEY CS800X’s for my pair of Calibres. They could care less.
This is them being built at the Legacy facility
