Altec 416-8A (c. 1960s–1970s)
A 15-inch Alnico V low-frequency loudspeaker used in high-end Altec systems, known for robust construction and warm, powerful bass.
Overview
The Altec 416-8A is a 15-inch low-frequency loudspeaker (woofer) manufactured by Altec Lansing. It was designed for professional and high-fidelity consumer audio systems and is recognized for its durable build and rich bass response. The driver features an Alnico V magnet, contributing to its dynamic performance and sought-after vintage sound. It was used as the woofer in the Altec A7 3-way speaker system, often paired with the 1003B midrange and 299-8A or 511B/808-8A high-frequency components in factory enclosures like the 825 cabinet. Enthusiasts continue to value the 416-8A for restoration and custom builds, though the lack of official Thiele-Small parameters presents challenges for modern enclosure design.

Its use in factory-built 825 plywood cabinets with 511B horns and 808-8A compression drivers reflects its role in fully engineered, matched systems.

The 416-8A remains collectible, with used pairs listed around $300 and individual units available for over $350 in used or parts-only condition. Refurbished examples exist, often updated with modern cone kits while retaining original components like the dust cap.
