Bang & Olufsen Beolab 606 (1984)
The Bang & Olufsen Beolab 606 came out in 1984 as part of B&O's Beolab series of active loudspeakers. The amplification sits inside the speaker cabinet, which was a break from the passive speaker norm of the era. That let the amplifiers be tuned to the drivers, and the sound quality set a new benchmark in audiophile circles.
Design and Aesthetic Philosophy
The Beolab 606 follows Scandinavian minimalism. It has a cylindrical aluminum enclosure in silver or black anodized finishes, with a fabric-covered front baffle that houses the drivers. The shape reduces internal standing waves, and the materials provide rigidity and dampen resonance. It is compact, which suits domestic rooms and modern interiors.
The base has a swivel mechanism, so the speaker can be angled toward the listening position. There are no external grilles, which gives the Beolab 606 a futuristic look that still holds up decades after its release. It was often paired with other B&O components such as the Beomaster 9000 or Beovox amplifiers.
Technical Specifications and Engineering
The Beolab 606 is an active two-way speaker. Each unit contains its own dedicated internal amplification, rated at 150W peak power output. Separate amplifiers drive the low/mid and high-frequency sections. This bi-amplified design gives precise control over each driver, minimizing distortion and maximizing dynamic range.
The woofer is a 13 cm (5.1-inch) aluminum cone that handles midrange and bass. The tweeter is a 2.5 cm (1-inch) textile dome for high frequencies. The crossover is active and sits before the amplification stage, which allows sharper filtering and better phase coherence than the passive crossovers in traditional speakers. Frequency response runs from 52 Hz to 20 kHz. That doesn't reach the deepest bass, but it is impressive for a speaker of this size.
Impedance is rated at 8 ohms, which makes it compatible with a wide range of B&O and third-party preamplifiers and control units. Sensitivity is approximately 88 dB, so it performs efficiently without needing excessive input power. The speaker is a bass reflex design with a rear-firing port to boost low-frequency output, which helps give a fuller sound from the compact cabinet.
The Beolab 606 works with B&O's proprietary connection system. A single multi-pin cable carries both audio signals and power from a compatible control unit or amplifier. This reduced clutter and kept signal integrity high. Later models and adapters allowed use with standard RCA or XLR inputs.
Sound Characteristics
The sound of the Beolab 606 is often described as clear, detailed, and balanced. The active design gives tight control over the drivers, which results in precise imaging and a wide soundstage. The aluminum woofer delivers articulate midrange and surprisingly robust bass for its size. The soft-dome tweeter gives smooth, non-fatiguing highs, good for extended listening sessions.
Because it is active, the Beolab 606 does not rely on external amplification for tonal character. It presents a neutral, transparent sound that reproduces the source material faithfully, which suits critical listening and high-resolution audio formats. Audiophiles often praise how it renders subtle nuances in vocals and acoustic instruments, with a spatial realism that few passive speakers of the era could match.
The compact size does impose limits. The bass is well-tuned and punchy, but it lacks the sub-bass extension expected in modern full-range systems. For deeper low end, B&O offered complementary subwoofers such as the Beolab 5000 or Beolab 7000, which could be integrated into a multi-channel setup.
Market Position and Legacy
At release, the Beolab 606 was a premium product, in line with B&O's strategy of combining luxury design with cutting-edge technology. It was not meant for the mass market but for customers who valued both aesthetics and audio fidelity. Its price put it among the most expensive speaker systems available, and for many buyers the build quality, performance, and longevity justified it.
The Beolab 606 stayed in production for several years and gained a loyal following among audiophiles and design enthusiasts. It is now considered a classic of 1980s audio engineering and is frequently sought after in the vintage hi-fi market. Well-preserved units, especially those with original components and finishes, can command high prices at auctions and specialty retailers.
Restoration and Modern Use
A pair of Beolab 606 speakers needs some attention to keep running. The internal amplifiers may need servicing after decades of use. Common issues include aging capacitors, failing power supplies, and degraded connectors. There is an active community of B&O specialists and technicians who offer refurbishment, including recapping, driver reconing, and firmware updates where applicable.
The Beolab 606 can be used in contemporary systems with adapters or external preamplifiers that have appropriate outputs. Some enthusiasts pair them with modern DACs and streamers for high-resolution digital audio.
Conclusion
The Bang & Olufsen Beolab 606 stands as a testament to the company’s philosophy that audio equipment should be as beautiful as it is functional. More than four decades after its introduction, it continues to captivate with its elegant design, advanced engineering, and exceptional sound quality. It represents a pivotal moment in the evolution of active loudspeakers and remains a symbol of Danish design excellence in the world of high-fidelity audio. Whether displayed as a design object or used as a serious listening tool, the Beolab 606 endures as a true classic.
