[Vintage-Audio] Speaking On Speakers

[Duane Fischer, W8DBF]

Now I realize I am probably drawing a battle line in the sand by approaching
this topic, but I am bored, it is hotter than a Beavers butt in a blow drier in
MI and I need some excitement besides listening to the condensation water drip
off the toilet tank onto the bathroom floor! 	
	
So here we go: 	
	
There were many different designs for speakers in the middle to late sixties.
Some were air suspension, some were floor firing, some used permanent magnets,
some used electromagnets and some used ... Some cabinets were infinite baffle,
some were bass reflex and others were folded horn. What was the supposed
advantage of the air suspension and other designs over the traditional pm
speakers with front firing ports? Leave price out as a factor, I understand the
cheaper concept, which is generally not related to better or more efficient. 	
	
Thanks.
