Maybe I'm reading your post wrong, but it's the pitch of the blades that will determine the frequency of the sound, the fan itself will spin at a constant velocity. As long as the blades can change pitch at a very rapid pace (which I hope it could), it should have no problem. One of the websites linked had a great picture of it in motion (not at full speed but it shows the blades pitch up and down).
As an interesting side note (at least to me, lol), in one of my AE classes we made a variable pitch prop (VPP) for an scale aircraft. It turned out to work extremely well, I'm sure 'the sub' uses some of the same principles as the VPP, as far as airflow is concerned.

I think it's more of a shock and awe thing. I doubt anyone would ever describe it as "musical."
