Anyone tried this mid driver?

Came across this new mid driver from B & C, the DCM 420. Specs look very good & the price is not too bad.

I found this while I was about to order a pair of DCM 50's, which are for my build of a pair of Belle Klipsch's. I've used the DCM 50 before in a similar build & really liked the sound of them, but see that the 420's are a fair bit less expensive, so wondering if anyone has ever heard them.
