Altec Lansing 416-8B (1975)

Name: Altec 416
Brand: Altec

At 17.5 pounds, it hangs in your hands like a foundry casting - dense, deliberate, built for war.

Overview

The Altec Lansing 416-8B is a 16" low-frequency loudspeaker of professional quality, introduced in 1975 as part of Altec's push into high-power, high-fidelity woofers for both sound reinforcement and critical listening. It looks imposing and it is heavy, but it was not designed to stand alone. It needs a horn-loaded midrange or compression driver to make a full-range system. It was originally intended for the Altec A7 system and later turned up in consumer products like the Valencia speaker line. The 17.5 pounds come from a massive 4.5 kg Alnico V magnet and a rigid die-cast frame. This is not a domestic curiosity. It was built to endure touring rigs and studio monitoring duty.

Owners report that despite its age, the 416-8B remains sought after by DIY audio builders and vintage PA restorers. Its frequency response of 25 Hz to 1,600 Hz lets it anchor a system without a separate subwoofer in many enclosures, and the 102 dB sensitivity (New JIS) gives high output with moderate amplifier drive. The voice coil is edge-wound copper ribbon, a rare and costly construction method, and it helps the driver handle thermal stress and deliver tight transient response under load. The downside is that, like many Altec drivers of the era, the cone suspension can fatigue over decades. When the surround degrades, the bass turns "mushy." The 15" outside diameter cone is shared with other models in the 416 series, so reconing is a viable path to restoration.

The 416-8B is often compared to the earlier 416-8A. Collectors note that the two share nearly identical specifications, but the mounting differs. According to user reports, the 416-8A was designed for rear baffle mounting, while the 8B suits front-mount applications. That is a small difference, but a critical one for system integration. It suggests Altec was tailoring the mechanical design to specific cabinet layouts rather than changing the acoustic performance. The 76 mm (3") voice coil allows extended power handling and reduced compression during long runs.

Key Features

Alnico V Magnet System

The 4.5 kg Alnico V magnet is central to the 416-8B's performance. It delivers a magnetic flux density of 12,000 gauss, exceptionally high for a production woofer of its era. A strong, stable field improves motor linearity and reduces distortion, especially at high excursions. Unlike the ceramic magnets that became common in later designs, Alnico has a smoother saturation characteristic, which contributes to the "musical" reputation many users give these drivers. Alnico is also more expensive and can demagnetize from physical shock or improper handling. That is a risk during transport or cabinet modification.

Edge-Wound Copper Ribbon Voice Coil

Few woofers ever used edge-wound ribbon wire in their voice coils, and the 416-8B is one that did. In this construction, flat copper strips are wound on-edge. That increases packing density and surface area, improves heat dissipation, and lets the coil survive prolonged high-power operation. The 76 mm (3") coil diameter adds thermal capacity and control over the cone. The design reduces electrical resistance slightly, but its main benefit is mechanical: tighter coupling between the magnetic field and cone movement, giving faster attack and cleaner bass transients. It raised manufacturing costs.

Dual Baffle Mounting Configuration

The 416-8A and 416-8B share nearly identical specifications, but they mount differently. Collectors note that the 416-8A was designed for rear baffle mounting, likely to suit specific enclosure designs in professional systems. This suggests Altec was not merely rebranding but adapting the same acoustic platform for different installation needs. The shared cone size (15" outside diameter) and the available reconing kits make the 8B a practical choice for restorers who want to keep it original and still be able to service it.

Collectibility & Value

Market observations suggest a mint pair of 416-8B woofers can command $500 to $600, with potential for higher prices among dedicated collectors. Units listed "for parts or not working" appear regularly on auction sites, which points to a steady supply of project-grade drivers. The primary failure mode is fatigued cone surrounds and the loss of definition that follows. It is well documented, and reconing kits for the shared 416 series cone make functional restoration feasible. Given their use in both professional and high-end consumer systems, surviving examples in good condition are increasingly rare.
