A high-efficiency, 4-way bass-reflex bookshelf speaker system designed for professional monitoring and precise sound reproduction.

Overview

The Altec Lansing 6041 Monitor, released in 1980, is a 4-way, 3-speaker bookshelf system built as a full-fledged professional monitor. It combines a 38 cm coaxial unit (604-8H) for mid and high frequencies, a dedicated 38 cm cone woofer (416-8BSW) for low frequencies, and a horn-type tweeter (6041-ST) for super high-range reproduction. Designed for clarity and strong sound localization, it delivers well-separated audio and is highly rated for both music listening and studio monitoring applications.

Design

The 6041 uses a coaxial 604 series unit (604-8H) with Altec’s original Mantare Horn and "Tangerine" radial phase plug for improved high-frequency response. The low range is handled by the 38 cm 416-8BSW woofer, which features an enhanced vibration system for better texture and volume in bass reproduction. A dedicated horn-type tweeter (6041-ST) ensures extended super high-range response. All drivers use Alnico V magnets. The crossover includes level controls for mid, high, and ultra-high frequencies and is designed to manage phase differences. The enclosure is constructed from 25 mm thick super-hard particleboard with computer-optimized porting, internal volume, and reinforcement to minimize box noise and deliver rich, powerful bass with wide directivity.

Reception

The 6041 is praised for its overwhelming sound localization and high efficiency, producing clear, well-separated sound that excels in both music playback and professional monitoring environments.
