Those looks good, not crazy good but good!
It's still a conventional tweeter even if full range. The circular design and marketing announce lead to believe it's some circular tweeter but no.

I can see M going to change completly its higher range and going with exotic drivers like ribbon tweeters (they did that for their wall-in range) or even a circular � la Quad electrostatic speakers! I am not convinced by the high tech plastic, but at 18kg they surely pack a lot of plastic!

I am not skeptical about those ones, M released them so they must sound good. Why wouldn't they?
