Altec 1219B ([1958])

Name: Altec 1219B
Brand: Altec

The Altec Lansing 1219B is a vintage loudspeaker enclosure that emerged during a pivotal era in audio engineering—the late 1950s—when high-fidelity sound reproduction was transitioning from novelty to necessity. Though often overshadowed by more celebrated models like the iconic 604 or 811A, the 1219B holds a distinct place in Altec Lansing’s product lineage as a purpose-built bass reflex (vented) enclosure designed to complement midrange and high-frequency drivers in professional and audiophile-grade systems.

Manufactured starting in 1958, the 1219B was not a complete speaker system in itself but rather a passive enclosure engineered to house a single 12-inch low-frequency driver. It was typically paired with Altec’s high-efficiency compression drivers and crossover networks to form complete two- or three-way systems. The enclosure was commonly used in broadcast studios, movie theaters, and early public address systems, where extended low-frequency response and durability were essential.

Design and Construction

The 1219B features a rectangular, trapezoidal cabinet design constructed from high-quality Baltic birch plywood, a material choice typical of Altec Lansing’s commitment to robust build quality. The trapezoidal shape helps reduce internal standing waves and cabinet resonance, contributing to cleaner bass reproduction. The front baffle is reinforced and designed to accommodate a single 12-inch speaker, while the rear panel includes a removable access panel for internal driver mounting and crossover placement.

One of the defining characteristics of the 1219B is its bass reflex tuning. The enclosure includes a port (vented opening) on the front baffle, just below the speaker mounting location. This port is carefully sized and positioned to enhance low-frequency output by allowing controlled airflow from the cabinet, effectively extending bass response down to approximately 45 Hz, depending on the driver used. This design was advanced for its time and reflected Altec’s deep understanding of acoustic loading and cabinet resonance management.

The standard finish for the 1219B was a textured gray hammertone paint, typical of Altec’s professional equipment of the era. The front grille is a stamped steel mesh, painted black, offering protection while minimizing acoustic diffraction. The overall dimensions are approximately 22 inches high, 14 inches wide, and 11 inches deep, making it a substantial but manageable enclosure for studio and installation use.

Technical Specifications and Performance

The 1219B was designed to work optimally with Altec’s 12-inch low-frequency drivers, most commonly the Altec 1230B or 1235B. These drivers featured large 3-inch voice coils, cast aluminum frames, and high power handling—up to 35 watts continuous (140 watts peak), which was considerable for the time. The system impedance was typically 16 ohms, allowing for efficient use in multi-speaker installations with constant-voltage distribution systems (70.7V lines), widely used in commercial audio.

The nominal sensitivity of the system when paired with the 1230B driver was around 98 dB (1W/1m), making it highly efficient and well-suited for use with tube amplifiers, which were standard during the era. The crossover point for systems using the 1219B was typically set between 600 Hz and 800 Hz, depending on the midrange driver used (such as the 515C or 518A).

Frequency response for the complete system (with appropriate drivers) ranged from approximately 45 Hz to 6 kHz, with the 1219B handling the lower end. The bass reflex tuning provided a +3 dB boost around 60 Hz compared to a sealed enclosure, enhancing punch and presence in speech and music applications.

Applications and Historical Use

The 1219B found widespread use in professional environments. It was a common sight in radio and television broadcast control rooms, where accurate monitoring was crucial. Its durability and extended low end also made it popular in movie theaters, particularly in surround or subwoofer roles before the advent of modern surround sound formats.

In the realm of live sound, the 1219B was sometimes used in touring PA systems, often stacked or flown in arrays with horn-loaded mid and high-frequency cabinets. Though not as portable as later designs, its rugged construction allowed it to withstand the rigors of regular transport.

Interestingly, the 1219B also gained a following among early hi-fi enthusiasts. Audiophiles in the 1960s and 70s would often build custom systems around Altec components, using the 1219B as the foundation for full-range speakers. When paired with a 515C midrange and a 802 or 808 high-frequency horn, the result was a system capable of high sound pressure levels and dynamic range—ideal for jazz, orchestral, and vocal recordings.

Legacy and Collectibility

Today, the Altec Lansing 1219B is considered a collectible piece of audio history. While not as widely recognized as the 604 Duplex, it represents Altec’s systematic approach to speaker system design—where every component, from driver to enclosure, was engineered to work in harmony. Original units in good condition are sought after by vintage audio restorers and studio historians.

Restoration projects often involve replacing aging speaker surrounds (typically from foam to butyl rubber), rewiring, and sometimes upgrading internal crossovers while preserving the original aesthetic. Some modern builders use the 1219B enclosure with contemporary drivers to blend vintage looks with modern performance.

The 1219B also serves as a testament to Altec Lansing’s influence on professional audio. The company, formed in 1941 through the merger of Altec Service Corporation and Lansing Manufacturing Company, became synonymous with reliability and sonic excellence. The 1219B, though not a flagship product, exemplifies the company’s commitment to functional, acoustically sound design.

Conclusion

The Altec Lansing 1219B may not be the most famous speaker in the Altec catalog, but it is a well-engineered, historically significant enclosure that played a quiet but vital role in the evolution of professional audio. Its bass reflex design, robust construction, and compatibility with high-efficiency drivers made it a reliable workhorse in studios, theaters, and broadcast facilities.

For collectors and vintage audio enthusiasts, the 1219B offers a tangible connection to a golden era of sound reinforcement and high-fidelity reproduction. Whether restored to original specs or adapted for modern use, it remains a respected piece of audio heritage—a functional artifact from a time when craftsmanship and acoustic science went hand in hand.
