Bang & Olufsen BeoLab RX Turntable (1972)

Name: Bang & Olufsen Beolab rx
Brand: Bang & Olufsen

The Bang & Olufsen BeoLab RX series, introduced in 1972, represents a hallmark of Danish audio innovation and minimalist design. As part of B&O’s high-fidelity system components during the 1970s, the RX turntables combined advanced engineering with elegant aesthetics, setting new standards for both performance and user experience in home audio.

Available in multiple variants—including the RX, RX2, and RX3—these turntables were designed to integrate seamlessly with other B&O components such as the BeoSystem 2500 and BeoCom 5000. The RX series remains highly regarded among audiophiles and collectors for its precision mechanics, low noise, and pioneering use of tangential tracking technology.

Historical Context

The BeoLab RX series emerged during a golden era of high-fidelity audio, when Bang & Olufsen was redefining the intersection of technology and design. With its clean lines, brushed aluminum accents, and intuitive operation, the RX turntable embodied the principles of Scandinavian modernism.

One of its most significant innovations was the optional tangential tonearm featured on the RX2 model. Unlike conventional pivoted arms, this linear-tracking mechanism moved the cartridge in a straight line across the record, eliminating tracking error and distortion. While not the first tangential arm, B&O’s implementation brought this high-end feature into the consumer market with remarkable reliability.

The RX series was often paired with B&O’s proprietary loudspeakers and control units, forming part of a modular audio ecosystem. Its automatic functions—such as tonearm return and speed selection—were considered cutting-edge at the time, emphasizing ease of use without sacrificing performance.

Sound Signature

The BeoLab RX delivers a clean, neutral, and highly detailed sound profile. Thanks to its rigid construction, low-resonance chassis, and precision-engineered MMC cartridges, it reproduces music with exceptional clarity and minimal coloration.

Bass: Tight and well-controlled, with excellent pitch definition
Midrange: Transparent and natural, ideal for vocal and acoustic recordings
Treble: Smooth and extended, without harshness
Imaging: Precise stereo separation, enhanced by accurate tracking (especially on RX2)

The use of B&O’s proprietary MMC cartridges contributes significantly to this performance, offering high compliance and low distortion. However, their proprietary nature presents challenges today, as original units are no longer in production.

Maintenance and Tips

Due to its age, proper maintenance is essential to preserve the performance and longevity of the BeoLab RX:

Common Issues & Solutions

Belt Degradation: The rubber belt can dry out or stretch over time. Replace with a high-quality OEM or compatible silicone belt every 10–15 years.
Tonearm Mechanism: The automatic lift and return system relies on delicate gears and linkages. If sluggish or noisy, disassembly and lubrication by a qualified technician are recommended.
MMC Cartridges: Original B&O MMC cartridges are obsolete. While some can be retipped by specialist services, alternatives include adapting modern cartridges (with alignment adjustments) or sourcing NOS (New Old Stock) units.
Capacitors and Wiring: Internal power supply units (for motor control) may contain aging capacitors. Consider a safety check and recapping if the unit has been stored for decades.
Dust Cover: Clean with a microfiber cloth and non-abrasive cleaner. Avoid ammonia-based products that can cloud acrylic.

Usage Tips

Always use a record weight or clamp to improve stability and reduce resonance (especially on warped records).
Store the turntable in a dry, dust-free environment with the cover closed.
Use a quality phono preamp with appropriate loading for MMC cartridges (47kΩ input impedance).
For RX2 models, ensure the linear tracking mechanism is free of obstructions and properly calibrated.

Collectibility and Market Value

The BeoLab RX series holds a collectibility rating of 7/10, driven by its iconic design, engineering pedigree, and association with B&O’s golden era. The RX2, with its tangential arm, commands the highest interest among audiophiles.

Condition	Estimated Value (USD)
Excellent (fully serviced, original parts)	$400–$600
Good (functional, minor wear)	$250–$400
Poor (needs restoration)	$150–$250

Units with original packaging, manuals, and accessories may fetch premiums from collectors.

Conclusion

The Bang & Olufsen BeoLab RX is more than a turntable—it’s a piece of audio history. Combining groundbreaking engineering with timeless design, it remains a testament to B&O’s philosophy of form following function. While maintenance challenges exist due to age and proprietary parts, a well-cared-for RX delivers listening pleasure that rivals many modern turntables.

For vintage audio enthusiasts, interior designers, or fans of Scandinavian design, the RX series is a worthy addition to any collection or listening room.
