That's largely true and was a big part of their appeal, especially in a time before the widespread availability of good analysis tools and predominantly in-the-box production (which removes all manner of subtle audio problems, from mismatched impedance to phase problems, from the conversation).

That said, I think there's a temptation to exaggerate. A phrase like "brain-fryingly bright tweeters" means something completely different to someone who isn't an audio engineer than it does to someone who's worked in studios or dealt with pro gear. NS10s, while harsh by studio monitor standards, are likely indistinguishable from other mid-range speakers of the era to the average listener. The difference is small, and only really becomes an issue with extended critical listening...8 hours sitting dead center in front of these speakers does feel brain-frying. But, a casual listen wouldn't reveal that. They'd sound like punchy, bright, tight, speakers. Which is what most studio monitors sound like to untrained listeners.

Which is why I'm kinda shaking my head at the comments here saying that NS10s sound "terrible"! It's just not true. They sound like what they set out to make them sound like. And, most importantly, the resulting recordings that came out of more than a decade of market dominance speaks for itself.

They aren't terrible speakers. They were a pretty good quality professional tool used by many professionals for many years to excellent results.
