Historical Context

The Altec Lansing 805B is part of the legendary "Voice of the Theatre" series, a family of horn loudspeakers developed by Altec Lansing for professional audio environments. Introduced in the early 1950s, the 805B evolved from earlier models like the 805A, featuring improvements in horn geometry and driver integration.

Its multicellular exponential horn design was engineered to control sound dispersion, minimizing reflections and ensuring even coverage across large venues. This made the 805B a staple in movie theaters, broadcast studios, and public address systems throughout the 1950s and 1960s.

As high-fidelity home audio gained popularity, audiophiles began adopting the 805B for its unmatched clarity and dynamic range. When paired with a suitable low-frequency enclosure—such as those housing 15" or 18" woofers—the system delivered a full-range, high-efficiency listening experience that few contemporaries could match.

The 805B exemplifies the golden era of American loudspeaker design, where efficiency, durability, and sonic precision were paramount. Its continued use and collectibility underscore its lasting impact on both professional and consumer audio.

Sound Signature

The Altec 805B delivers a vivid, immediate sound characterized by exceptional clarity and dynamic punch. Its high sensitivity allows it to produce high sound pressure levels with relatively low amplifier power, making it ideal for tube amplifier setups.

Midrange: The standout feature—crisp, lifelike, and highly detailed. Vocals and acoustic instruments are rendered with remarkable presence.
High Frequencies: Extended and energetic, though some users find them bright or forward, especially with modern recordings.
Bass Response: Limited by design; the horn only reproduces mid and high frequencies. Deep bass must be provided by a companion woofer system.
Overall Character: Transparent, dynamic, and engaging—perfect for jazz, classical, and vocal-centric genres.

Maintenance and Restoration Tips

Due to their age, surviving 805B units often require maintenance to restore optimal performance:

Compression Driver Inspection: Check the diaphragm for tears or warping. Original Altec 288 drivers may need re-coning or remagnetization. Consider professional restoration services.
Horn Integrity: Inspect the multicellular horn for cracks, dents, or delamination. Surface corrosion on the aluminum throat can affect high-frequency response.
Crossover and Wiring: If used in a multi-way system, verify the condition of passive crossovers. Replace aging capacitors and inductors to prevent distortion.
Mounting and Placement: The 805B benefits from proper positioning—aimed toward the listening area and isolated from vibrations. Use sturdy stands or wall mounts.
Pair Matching: For stereo use, ensure both horns are restored to the same specification to maintain balance.

Collectibility and Market Value

The Altec 805B Horn is highly collectible, earning an 8/10 on the vintage audio scale. Its value depends heavily on condition, originality, and the type of compression driver installed.

Market Value: $800 – $2,500 per pair
Factors Affecting Value:
Original Altec 288 driver (higher value)
All-original finish and hardware
Provenance (e.g., studio or theater use)
Restoration quality (non-invasive, period-correct parts)

Units with documented history or rare variants (e.g., special finishes or military use) can command premium prices at auction or among private collectors.

Conclusion

The Altec Lansing 805B Horn is more than a speaker—it's a piece of audio history. Its combination of engineering brilliance, sonic excellence, and enduring design has secured its place in the pantheon of classic loudspeakers. Whether used in a vintage hi-fi setup or preserved as a collector's item, the 805B continues to inspire awe and admiration among those who value the golden age of sound reproduction.
