most accurate loudspeakers....

ATC and/or PMC are anything but flat and accurate. One more myth that some clever marketing guys had manage to sell the public. If you look at the history of ATC you realize why it is popular in studios. It has nothing to do with the way they sound.

Perhaps, but it was mainly the fact that they can play loud and not break. You know, like typical PA speakers.

Well loud yes but at what distortion level? A car horn can produce a 120db tones anytime. That is why you do not use PA speakers in your home. There is a big difference between the need to simply amplified and the need to accurately amplified. And when I say accurate, I mean liner FR and low distortion. Two things that PA systems are not very good at.

Gregm- I have my doubts. The only independent measurements I have ever seen of an ATC speaker were not very impressive. On the contrary. The distortion levels of their dome midrange was completely unacceptable (Stereo Sound issue 155).
I must say, that to my ears, that is how they sound as well. Especially when driven hard. They get harsh and glossy sounding as soon as you push them.

Shadorne - Thoughtful reply. Thanks. I think that it is difficult to keep IMD down with any “soft” dome. You are practically operating in a non-pistonic way. Not ideal for “moving air”. Yes the dispersion of a dome mid is very nice but it takes more to tango. The MAGICO’s do use an incredibly stiff, yet well damped, cones. The dealer had a cone on hand to demonstrate how he can stand on an 8 grams 6” cone and not break or bent it. Very impressive. I have notice how easily you can push the V3 to dangerous SPL without realizing it. Clear sign of low distortions. I got to watch out, my wife claims I am losing my hearing… One of these days I will post my system up. It is always too messy to photograph. Not too fancy but I think that if nothing else, linear with very low levels of distortion.
