Altec 416-8A (c. 1960s–1970s)
A 15-inch Alnico V low-frequency loudspeaker used in high-end Altec systems, known for its construction and warm, powerful bass.
Overview
The Altec 416-8A is a 15-inch low-frequency loudspeaker (woofer) made by Altec Lansing. It was designed for professional and high-fidelity consumer audio systems, and it is known for a durable build and strong bass response. The driver has an Alnico V magnet, which adds to its dynamic performance and its sought-after vintage sound. It was 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 still use the 416-8A for restoration and custom builds. There are no official Thiele-Small parameters, which makes modern enclosure design harder.

Design
The 416-8A uses an Alnico V magnet structure, known for a strong magnetic field and smooth tonal characteristics. Aftermarket recone kits made for the 416 series fit it, so aged or damaged units can be restored. The construction supports high excursion and durability, which suits demanding audio work.
Context
The 416-8A was the low-frequency driver in the Altec A7 3-way system, a high-performance speaker configuration used in both studio and home environments. It also went into the Altec Lansing Valencia consumer speaker line. It was used in factory-built 825 plywood cabinets with 511B horns and 808-8A compression drivers, as part of a fully engineered, matched system.
Market
The 416-8A is still collectible. Used pairs are listed around $300, and individual units go for over $350 in used or parts-only condition. Refurbished examples exist, often updated with modern cone kits while keeping original parts like the dust cap. Without published Thiele-Small parameters, enclosure design is more difficult, but reconing services and community knowledge support ongoing use and restoration.
