By the way, I usually don't just take someone's word for something - I usually try it out for myself. But about the KSC75's - I have a pair of PRO35A's that are about 3/4 open and they sound MUCH better when you just pop out the drivers and put them on a generic headband that allows them to operate totally free.
So yeah, I believe that they'd sound like crap in a totally sealed enclosure.
