I was at the Florida Audio Expo, and I have to admit, these are some darn good sounding speakers. Definitely "full range" on their own, but like any loudspeaker/room, they would benefit from a couple (or more) properly set up subwoofers.
Now, saying that the Clarisys Audio loudspeakers are better than Alsyvox loudspeakers, that's a rather BOLD statement. I have no say in the matter since I have never heard Alsyvox loudspeakers before. On a side note however, I did listen to the Diptyque DP107's, and those too were amazing sounding with plenty of "oomph" in the bottom end as well.
Of course, the room they had the Auditorium's in was huge, probably close to 20 ft wide and 40+ ft long with I'd say a 9 - 10 ft ceiling. They had around 6 - 7 ft behind them and had massive Block Audio mono amps pushing them.
This particular model, the Auditorium, is rated at 6 ohms, but they have a model (the Opera) that has a nominal impedance between 1 - 2 ohms! Yikes!
