[Vintage-Audio] Re Air Suspension Speakers

[Duane Fischer, W8DBF]

Hi All, 	
	
While wandering down memory lane around here, I recalled a friend in the late
sixties who had a so called 'portable' stereo that head some speakers with it
that were some kind of air suspension. They were not large, but did seem to
produce some large sound for their size. Now I won't swear to them being 'air'
suspension, but they were some kind of suspension. Do any of you remember these?
Did they really have some benefits to their design or was it the usual marketing
hype? 	
	
Thanks!
