JBL C-37 (circa 1965)
Not much is documented about the JBL C-37 enclosure. The record says it was a lowboy version of the JBL C-35, as noted in a period equipment directory from HiFI-Stereo (1965, p.141). That same source lists the C-35 as a large stereo speaker enclosure, 23½" wide, 20" deep and 51½" tall, meant for free-standing or wall-mounted use. It incorporates an exponential horn and a serpentine acoustic lens. The C-35 enclosure alone (less legs) was priced at $117.00. The exponential horn and serpentine acoustic lens were listed at $993.00, and the combination was described as part of a system that functioned as an "energizer/transducer." The C-37 appears to have been the lowboy variant of that same design. No separate specifications or production dates for the C-37 itself have been preserved in the sources available.
