Commentary
A floor-type speaker system that employs a rear-loading horn.
There were six variations in unit configuration.
The C40 used in the enclosure was designed as a horizontal model of the C34 and uses a rear loading horn (back load horn) system.
We also had left - and right-side enclosures for more faithful stereo playback.
