Well yeah... but "fantastic" is a very vague reference for performance/quality.
I think the point was that they needed to be installed and set up/tuned properly to perform like intended, something that didn't shine through when hearing them on a wall display in the shop.
I did talk to our local distributor up here in Norway, just after he came back from the Focal factory having listened to these at their launch. And the one thing that really stood out from before was that they had all the refinement from the old series (not surprising), but also a loudness factor that went beyond even the K2 power series.
So much more headroom than before, also the drivers had a very broad usable frequency range, so you could really mix and match drivers to suit your setup. Like the 8" was suited to use with just the tweeter for a 2-way setup. But also usable as a subwoofer.
Sadly they're out of my price range, as I would have very much liked to upgrade from my 3-way Focal Flax setup (PS165F3) to some configuration of Utopia M. Selling my 1st gen Utopia 3-way setup (audiom tlr, audiom 6w and utopia 7w2) wouldn't even cash in a single TBM tweeter I'm afraid!
