I worked with up to 66 l. Auratone QC They are super critical but super tiring.
I had Bose Hi Fi ct (as to program, or the dtendre Auratone is not a.) to rest a little now and then. I started at the top to sell the Bose to buy a pair deuxime critical and "relaxing". In the thrift shop that I took over the Bose, there was a pair of 4311. I love them. They are neutral enough as not to flatter and bring dceptions at Coutes ultrieurs on other speakers and they are pleasant. In addition, as domestic speakers, they are fantastic too. I added a pair of Bose 400. I do not regret at all.
They are drives by Samson 150. They are my main cost in the rgy technique. Locate each about 2 meters from each of my ears.
