Altec 828b
The Altec Lansing 828B is a landmark loudspeaker system developed in the mid-1950s, representing a golden era in American audio engineering. Introduced in 1955 by Altec Lansing, a company with deep roots in professional sound reinforcement and cinema audio, the 828B was designed as a high-fidelity, high-efficiency speaker suitable for both professional monitoring and high-end home audio applications. Its enduring reputation stems from its robust construction, innovative driver design, and exceptional sonic clarity—particularly in the midrange—making it a favorite among vintage audio enthusiasts, studio restorers, and audiophiles to this day.
The 828B is a two-way, bass-reflex loudspeaker housed in a large, trapezoidal cabinet constructed from high-quality plywood, typically finished in walnut veneer. This shape was not merely aesthetic; it was engineered to reduce internal standing waves and cabinet resonance, contributing to a cleaner sound. The front baffle is slightly angled, which helps with time alignment between the drivers and improves stereo imaging when used in pairs. The cabinet is internally braced and lined with acoustic damping material, a sophisticated design choice for its time.
At the heart of the 828B’s performance is its driver complement. The low-midrange section is handled by the Altec 515-8G, a 15-inch paper-cone woofer with a large magnet structure and a 3-inch voice coil. This driver is known for its high power handling (rated at 25 watts program), excellent transient response, and ability to produce deep, articulate bass when paired with the appropriate enclosure. The 515-8G was part of Altec’s renowned "Voice of the Theatre" (VOTT) series, originally designed for cinema sound systems where reliability and high output were paramount.
The high-frequency driver is the legendary Altec 802B, a 2-inch titanium diaphragm compression driver mounted on a large exponential horn. This driver, often referred to as the "screamer" due to its high sensitivity and dynamic punch, is one of the most iconic tweeters in audio history. It delivers exceptional clarity, wide dispersion, and a smooth, extended high-frequency response up to around 16 kHz. The 802B’s design prioritizes efficiency and low distortion, making it ideal for both live sound reinforcement and critical listening environments.
The crossover network in the 828B is a passive, first-order design, set at approximately 1,200 Hz. This simple yet effective crossover preserves phase coherence and minimizes signal loss, allowing both drivers to work in harmony. The crossover components—typically paper capacitors and air-core inductors—reflect the technology of the era and contribute to the speaker’s warm, natural tonal balance. While modern listeners might expect steeper crossover slopes, the 828B’s gentle filtering is part of what gives it its open, transparent sound.
One of the 828B’s most impressive specifications is its sensitivity: rated at 102 dB (1W/1m), it is an extremely efficient speaker. This high sensitivity allows it to produce substantial volume levels even when driven by low-power tube amplifiers, making it a perfect match for vintage electronics such as McIntosh, Fisher, or Marantz tube receivers from the 1950s and 1960s. Its 16-ohm nominal impedance also makes it compatible with a wide range of classic amplifiers designed for high-impedance loads.
Originally, the 828B was marketed as a professional monitor speaker, finding widespread use in radio broadcast studios, recording facilities, and movie theaters. Its ability to reproduce speech with exceptional clarity and presence made it a favorite for voice monitoring, while its full-range response and high output capability suited it for music playback as well. Over time, the speaker gained popularity in high-fidelity home audio circles, where its dynamic punch and midrange transparency were highly prized.
Despite its age, the 828B remains in demand today. Original units in good condition can command high prices on the vintage audio market. However, due to their age, many components—especially the foam or cloth surrounds on the woofers and the condition of the crossover capacitors—may require restoration. Re-coning services are available from specialized vintage speaker repair shops, and many enthusiasts upgrade the crossover components with modern equivalents while preserving the original sonic character.
It’s important to note that the 828B is a large speaker—approximately 30 inches tall, 15 inches wide, and 15 inches deep—requiring substantial space and proper placement for optimal performance. They perform best when positioned away from walls and corners, with careful attention to toe-in and room acoustics. Due to their rear-firing bass reflex port, they also need adequate clearance at the back.
While the 828B lacks the extended bass response of modern subwoofers or ported floorstanders, its bass is tight, fast, and well-integrated, especially for a speaker of its era. The combination of the 15-inch woofer and bass-reflex tuning delivers a balanced low end that complements the clarity of the midrange and highs without becoming boomy or sluggish.
In the context of audio history, the Altec Lansing 828B represents a bridge between professional sound engineering and consumer high fidelity. It embodies the design philosophy of the 1950s: durability, simplicity, and performance over marketing gimmicks. Its legacy lives on not only in restored vintage systems but also in modern speakers inspired by its design, such as reissues and homages from boutique manufacturers.
In summary, the Altec Lansing 828B is more than just a vintage speaker—it is a piece of audio history. Its combination of high efficiency, robust construction, and legendary drivers like the 515-8G and 802B ensures its place among the greats of mid-century loudspeaker design. Whether used in a restored hi-fi setup, a vintage studio, or a modern system seeking classic tube-era warmth, the 828B continues to deliver a listening experience that is both powerful and emotionally engaging. For collectors and audiophiles alike, it remains a benchmark of American audio excellence.
