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:


LWE-1 - a three way system using
a 15" CTS woofer, a 6" CTS solid-back midrange and an Electro-Voice T-
35 tweeter horn mounted in a speaker cabinet with dimensions of: 25"
H, 17" W, 12" D. Power rating: 50 watts. Resistance: 4 ohms.
Frequency response is 22 Hz - 20 kHz. SPL rated at 96 dB/per watt @
1m. Room gain control, mid and high level controls.


Has anyone measured frequency response of these by post-1971 methods?
