Altec Lansing Model 15 (1976)
A floor-standing, bass reflex speaker system released in 1976 with a 2-way, 2-speaker design and independent mid/high frequency level control.
Overview
The Altec Lansing Model 15 is a floor-type speaker system introduced in 1976. It features a 2-way, 2-speaker configuration with a bass reflex enclosure design. The system uses a 30 cm cone-type woofer equivalent to the 414 to 8 b model for low-frequency reproduction, paired with a horn-type high-frequency unit combining a Tangerine driver and dedicated horn. Designed for home use, the horn provides 120° horizontal dispersion and is optimized for close-range listening. The crossover frequency is set at 1.7 kHz, and the internal network allows independent level control of the mid and high bands.

Design
The Model 15 uses a Tangerine driver in the high-frequency section, paired with a dedicated L-shaped wide-directional horn that provides 120° horizontal dispersion, a trait shared with the A-8 and other Altec Lansing models. This radial horn design delivers simple transmission characteristics suited for domestic environments. The low-frequency section houses a 30 cm cone-type woofer equivalent to the 414 to 8 b. The enclosure employs a bass reflex system to enhance low-end response. The internal crossover network includes level controls allowing independent adjustment of mid and high-frequency output.
