[Dixielandjazz] For you "Hi-Fi" fanatics: a Woofer that goes down to 1 Hz!

[David Richoux]

Got this info from the Contrabass music &  instrument list:



> Eminent-Tech has introduced a woofer that appears to bounce sound off 
> the blades of a fan and goes down to 1 Hz (or, actually, DC).  It's 
> smaller than a breadbox, has to be installed in your attic or basement 
> and costs a modest $12,900.  You'll of course need two for stereo, or 
> perhaps seven for surround sound.

(actually, only one would be needed because low frequencies are not 
very directional.)
