JBL Hartsfield (1954–1960)

Name: JBL Hartsfield
Brand: JBL

A horn-loaded loudspeaker kit designed by Bart N. Locanthi. In the 1950s it was called a high-fidelity breakthrough for home audio.

Overview

The JBL Hartsfield was a high-end horn-loaded loudspeaker system sold as a kit between 1954 and 1960. Bart N. Locanthi designed it. It was a bold step toward bringing true high fidelity into the home during the early stereo era. It was marketed to modern, style-conscious buyers - often described as fitting for "Space Age bachelor pads" - and it stood out for its striking presence as much as for its sound. In the 1950s, Life magazine called it the "dream speaker." It could be purchased assembled, and technically inclined users could also build and customize the system themselves.
