Altec 8020 (c. 1957–1961)

Not much is documented about the Altec 8020 as a standalone component. The record shows it was a high-frequency driver in Altec Lansing's professional and high-fidelity speaker-component line during the late 1950s and early 1960s.

The 8020 shows up most visibly as the tweeter in Altec's Capistrano 831A complete loudspeaker system. An Audio advertisement (December 1960, p.47) described the Capistrano as housing "one 15″ 803B controlled linear excursion bass speaker, an 8020 high frequency driver mounted on an 811B sectoral horn," with a guaranteed frequency range of 35-22,000 Hz. The system sold for $399.00 in walnut or mahogany.

Outside those period advertisements, no independent reviews, production dates, or detailed technical specifications for the 8020 driver alone have surfaced. It was almost certainly meant as a replacement or upgrade driver for Altec's sectoral-horn assemblies. Impedance, power handling, and diaphragm construction are absent from the surviving record.

Type: High-frequency compression driver
Known system use: Capistrano 831A (with 803B woofer and 811B horn)
