1Hz - that should put the wind up most listeners.

"Remember, response is FLAT to 1Hz, meaning there is virtually no
distortion" - most certainly a novel concept.

I wonder why it is only spec'd to 1Hz? Since it appears to be a fan,
why can't it continue to deliver SPL to DC, which I guess would be
leaving the fan running? :)

Finally, a speaker that can truly blow smoke up your butt!

The fan is always running at a constant speed. The tones come from
change in pitch in the propeller. A friend heard one at an audio show
here in Denver and said that the hotel walls were literally flexing.
They only had it set up for test tones, though. he didn't get to hear it
integrated into an actual music system.

I doubt its transient response is adequate for pro live sound; probably more
suitable for special effects, synth pedal tones, etc.

What kind of transient response do you need in a sub? Any part of the
waveform with a fast rise time will be filtered out by the LPF in the
crossover, and sent to the full range part of the system. I think tom
Danley or Intersonics built one from his patent doc:

http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=/netahtml/search-bool.html&r=1&f=G&l=50&co1=AND&d=ptxt&s1=5140641.WKU.&OS=PN/5140641&RS=PN/5140641

I don't know what it may have sounded like.

I was actually joking in the previous post about response to DC, but it
is described in Tom Danley's patent application as having response to
DC.

Would love to give it a try though - get a few double 18" of them! :-)

Here is where Tom Danley talked about what it sounded like:
