Altec 878A FLAMENCO (1971–1978)

At 49.9 kg, it doesn't just sit in the room - it claims it.

Overview

The Altec 878A FLAMENCO is a floorstanding speaker system built for presence, both physical and sonic. It was sold under the Flamenco name as part of Altec's home hi-fi lineup, which included the Valencia and Model 19. At $529 per speaker in the 1970s, this was not entry-level gear. It was for listeners who wanted professional-grade performance without the PA rig. The system evolved into the 878B, a later version with visual refinements like a black mesh three-dimensional grille and a natural slate top. The mission stayed the same: bring the Voice of the Theatre experience into the living room.

It's a 2-way, 2-speaker bass-reflex system. The ported cabinet tuning extends low-frequency response without needing massive amplifier power. The claimed frequency response of 35 Hz to 20 kHz was ambitious for its time, and the 96 dB/W/m sensitivity means it plays loud with modest input. Add an 8 Ω nominal impedance and 60W continuous program handling, and it works with a wide range of tube and solid-state amplifiers from the era. It is not a speaker for the space-limited, though. It stands 765mm tall and weighs nearly 50 kg each, and it needs room to breathe.

Owners report the 878A uses a combination of drivers that varies slightly between early and late runs. Some 878A units came with the 414 12" woofer, while others may have used different variants in the 400-series line. The high-frequency section pairs a 902 driver with the 811B sectoral horn, a design known for controlled dispersion and dynamic clarity. The crossover, an N801-8A or similar network, routes signals at 800 Hz. That point keeps the woofer out of its breakup zone and lets the horn take over where it excels. Internal damping is present, which suggests Altec paid attention to cabinet resonance, a common weak point in ported designs.

The 878A FLAMENCO doesn't enjoy universal acclaim. A post on Audioheritage.org once asked, "Why are the Altec Santiagos not regarded very highly by anyone?" Whether that's due to inconsistent build quality, the quirks of horn-loaded sound in domestic spaces, or simply shifting tastes, these speakers polarize. They don't offer the neutral, transparent sound modern listeners expect. Instead, they deliver a bold, forward midrange and punchy dynamics, the sound of a theater monitor adapted to home use. That wins fans, but it doesn't win awards for accuracy.

Key Features

Bass-Reflex Design with Tuned Port

The 878A's bass-reflex cabinet is engineered for extended low-end output. The port is tuned to reinforce bass response below the natural roll-off of the 12" woofer, allowing it to reach down to 35 Hz. That figure was likely measured under ideal conditions, but it still indicates strong sub-bass capability for a home speaker of the 1970s. The design increases efficiency and reduces cone excursion at low frequencies, which helps maintain clarity at higher volumes. Ported systems can suffer from time-domain smearing if not well designed, and owners note that placement is critical. Too close to a wall, and the bass can turn boomy.

811B Sectoral Horn with 902 Driver

The high-frequency section is where the 878A shines. The 811B sectoral horn provides controlled horizontal and vertical dispersion, which reduces ceiling and floor reflections that can muddy the sound. Paired with the 902 compression driver, it delivers the dynamic punch and vocal clarity Altec was known for in professional environments. This isn't a tweeter that whispers. It projects. The 800 Hz crossover point ensures the horn takes over before the woofer's upper-midrange distortions become apparent, preserving vocal intelligibility. Some users report that the horn can sound aggressive with bright recordings or poor amplification.

N801-8A Crossover Network

The N801-8A crossover is a passive network that splits the signal and protects the drivers. Given the age of these units, capacitor degradation is a common issue. The original components may have drifted in value or failed outright, leading to imbalanced output or even driver damage. Restoration almost always includes a recap, replacing electrolytic and paper-in-oil capacitors with modern equivalents. When fresh, the crossover integrates the woofer and horn smoothly, though its design reflects the component limitations of the early 1970s.

Walnut and Wood Veneer Finish Options

The 878A was built to blend into a high-end living space. It was offered in walnut and other wood veneers, and the cabinet avoids the industrial look of Altec's pro monitors. The finish was meant to impress. This was furniture as much as audio gear. Over time, the veneers can chip, fade, or suffer from water rings, so cabinet refinishing is a frequent part of restoration. The 878B added a natural slate top, but the 878A relied on the warmth of wood to sell its domestic appeal.

Internal Acoustic Damping

Altec included internal damping material to absorb standing waves and reduce cabinet coloration. It reflects an understanding that a clean enclosure is essential for accurate sound. Decades later, this material often degrades into a sticky mess or disintegrates entirely. During restoration, it's common to remove the old damping and replace it with modern acoustic wool or polyfill. The original design likely used fiberglass or mineral wool, which were effective but not built to last 50 years.

Historical Context

The Santiago, marketed as the 878A FLAMENCO, was introduced during the early 1970s as part of Altec's strategy to bring professional sound into the home. The "Voice of the Theatre" name referred to a lineage of speakers developed for cinemas and broadcast studios. The Santiago was an attempt to scale that performance down, not in output but in footprint and aesthetics, to fit in a living room. It arrived at a time when high-fidelity audio was becoming a middle-class aspiration, and manufacturers were racing to deliver concert-hall realism without concert-hall dimensions.

Collectibility & Value

Well-restored Santiago speakers typically sell for $1,500 - $2,500 per pair, a figure that reflects both their size and their cult following. The original price was $529 per speaker, or $1,058 for a pair. That was steep in the 1970s and placed them firmly in the high-end market. Today, their value depends heavily on condition and completeness. A pair with original grilles, undamaged veneer, and a recapped crossover commands top dollar. Those with blown woofers or brittle, degraded damping material require significant investment to restore.

Common restoration tasks include replacing capacitors in the N801-8A crossover network, inspecting the 411-8A woofer (or similar) for torn surrounds or misaligned voice coils, servicing the 806-8A compression driver (even if labeled as a 902, some variants share service procedures), refinishing the wood veneer, repairing or replacing the grille fabric, and cleaning out decades of dust from the cabinet interior. Spare parts are not manufactured anymore, so repairs rely on cannibalized units or third-party reconing services. There is no documented pattern of specific failures beyond the expected aging of capacitors and foam surrounds, but given their weight and complexity, shipping damage is a real risk in the used market.
