A bunch of us LWE speaker fanatics are collecting and sharing
information about these early (1965-71) servo loudspeakers. These are
the ones that Steve Zipser (RIP) used to rave about all the time on
usenet with the flat frequency response from 20hz-20khz:
I checked the site and the patents...
The trick is that the speakers have some networks worked in, I did not
look carefully at the networks to see their effect beyond that of an
xover. But the intended effect is to create a feedback loop from each
driver that results in a flattened response. In effect a sort of EQ it
would appear... maybe not a bad idea.
Bears some further investigation and maybe reading the patent carefully...
