Here is a review. They are already showing up in the barely used market.

I automatically ignore anything written by Steve Guttenberg at CNET. The guy writes like he’s getting kickbacks from Andrew Jones and ELAC. Just not a reliable source - especially re: ELAC products.
I should note my personal connection to the matter - I purchased a pair of Uni-Fi UB5s very early on the basis of Guttenberg's sunshine pumping review(s) and wasn't impressed. Some dude running a website called "noaudiophile" had a much more accurate description of the sound - which was basically "squawkbox past 95dB" - I couldn't have agreed more. Just not a pleasant speaker at higher than average volumes.
