The measurements are there to prove whether a claim is correct. ATC sells their wares based on reputability. They rely on rave reviews from so called industry professionals whose opinions are no better than the average person. There are no measurements to prove their superiority. Why dont ATC publish their measurements?
ATC are favored by studio engineers. But so are every other studio monitor company. Genelec, PMC, Barefoot, Kii audio, dutch and dutch, Adam, Krk the list goes on and on. They all sound different so they are all wrong and there is no justification to claim that ATC are superior. Zero evidence of that. There are fanboys of every speaker brand. ATC is nothing special. Ive personally heard ATC and didnt like them at all.
