What kills my interest in them is they are an enclosed system and not an open baffle. For the same amount of money these can be had which reading comments on another thread were pretty much the standout highlite at RMAF.
It's a great hobby we share, the beauty of which is that it's almost impossible for anyone to be
truly wrong. Perception really is reality, and what we like is always the right answer.
In that vein, I heard a lot of speakers at this year's RMAF, including the Emerald Physics and a lot of other speakers, open baffle and otherwise. Personally, I wouldn't trade my 'old' Timepiece 2.1s for any of 'em, straight up, though I will eventually have my pair upgraded to 3.0 status. My 2.1s are great, but the new all-Mundorf crossovers in the 3.0s is otherworldly.
Despite their conventional 'box speaker' appearance, the openness and free-flowing presentation of Bob's designs is unparalleled in my experience with 'box' speakers. It's more akin to an electrostatic with great big cojones. I'm sure this has a lot to do with the waveguide and superb crossover, and surely the rigidity of the enclosure itself plays an important role, but there has to be more to it. They're just so different, so much better to my ears than any speaker with which I'm familiar.
Anyway, as strongly implied above, to each his or her own. For me, I'll stick with SP Technology speakers until I hear something better.
