Altec 604-8H (1980)
A 16" coaxial driver with Alnico V magnets and the first 604 model to feature the Mantaray horn
Overview
The Altec 604-8H is a 16" coaxial speaker driver, part of the long-running Altec 604 Duplex series. It was used as the mid and high-frequency unit in the ALTEC LANSING 6041 Monitor system, released in 1980. This driver marks a transition point in the 604 lineage: it's recognized as the last version to use Alnico V magnets and the first to incorporate Altec's Mantaray horn. While no standalone specifications such as impedance or sensitivity are documented, it was designed for professional monitoring applications and rated for 65 watts of continuous pink noise.

Design
The 604-8H is a coaxial (Duplex) speaker design, combining mid and high-frequency reproduction in a single unit. It was the first 604 model to feature the Mantaray horn, improving high-frequency dispersion and response. Alnico V magnets are used in the magnetic circuit, a trait that distinguishes it as the final 604 variant to use this classic magnet material before later models transitioned to ceramic. The driver was specifically engineered for integration into the 6041 Monitor system, where it handled mid and high bands in conjunction with a dedicated 38 cm woofer and horn tweeter.
Market
A pair of Altec 604-8H drivers with original crossover and custom cabinets was listed for $2,850.00 USD, indicating strong collector interest. While no official original price or current production data exists, the driver's status as the last Alnico-based 604 and first with the Mantaray horn contributes to its desirability among vintage audio enthusiasts.
