Definitely, have a listen. I heard a set at a show, and found the sound to be pretty swell. I put them as punching in the same league as the Raidho and YG offerings that I also loved although the Raidhos were my clear favs, both the D1 and D2. Yes, please. (And, incidentally, found all three considerably more enjoyable than the mega-buck offerings from the likes of Wilson, Genesis, etc. But that's certainly a pretty random sampling, given the eccentricities one has to deal with at shows).
As for ported v. non-ported, think its impossible to make blanket statements about how either sounds across the boards. Either can be done right, and either can be done poorly. Think it all comes down to the execution in any given application.
Finally, the looks. Do not like. I couldnt live with it. Full stop. I didnt have the chance to try to knock one over, either. Generally, got the impression that sort of behavior would be frowned upon. But it didnt look like it would be too difficult....
