Arcam Radia Speaker Series – Arcam expands the Radia family with a complete line of loudspeakers

Within the contemporary HiFi and home cinema market, system thinking has become increasingly important. Manufacturers are no longer judged solely by individual components, but by how well products interact within a complete audio environment. Arcam, long established as a specialist for amplifiers and AV electronics, now addresses this shift directly by expanding the Radia family beyond electronics and into loudspeakers for the first time in decades.

Key Facts

• First complete Arcam loudspeaker range since the 1980s
• Designed for both stereo and multichannel home cinema systems
• Unified acoustic platform across all passive models
• Consistent visual design aligned with Radia electronics
• Broad model selection from compact bookshelf speakers to subwoofer
• Focus on system compatibility without mandatory electronics pairing

A system-driven return to loudspeaker design

With the Radia Speaker Series, Arcam deliberately avoids nostalgia. Instead, the company follows a clearly defined system concept aimed at flexibility and long-term compatibility. The loudspeakers are designed to integrate easily into a wide variety of HiFi and home cinema setups, without being tied to specific electronics. At the same time, users who combine the speakers with selected Radia amplifiers and AV components can benefit from more precise system matching and tuning options.

This dual approach defines the character of the series. The speakers remain fundamentally open, passive designs, yet reveal their full potential when electronics, loudspeakers and room are treated as a coherent whole. In this way, Arcam combines classical loudspeaker engineering with its long-standing expertise in modern audio electronics.

Historical context: Arcam and speaker

Although Arcam is primarily associated with electronics today, loudspeaker development is part of the company’s heritage. In the mid-1980s, the British manufacturer gained attention with the Arcam two compact speaker, underlining its holistic understanding of audio reproduction. In the following decades, however, the focus shifted almost entirely toward amplifiers, CD players and later AV components.

The Radia Speaker Series therefore represents a strategic return rather than a side project. Unlike the 1980s, Arcam now has access to advanced measurement tools, simulation methods and the broader development infrastructure within the Harman group. Despite these expanded resources, the core philosophy remains unchanged: loudspeakers are not isolated transducers, but integral elements within a complete audio system.

Design and construction: shared DNA across the series

Visually, the Radia Speaker Series is clearly part of the Radia ecosystem. The restrained, architectural design language of the electronics is carried over to the speakers, featuring black walnut veneer, clean cabinet lines and subtle yellow accents. The result is a visual coherence that integrates naturally into living spaces without drawing undue attention.

The cabinets are engineered for rigidity and control. Internal bracing is used throughout the range to reduce unwanted resonances and provide a stable operating environment for the drivers. Magnetically attached grilles ensure a clean front appearance, while optional aluminium stands for the bookshelf models extend the design concept into room placement.

From a technical perspective, all passive models share a common platform. Each uses the same 25 mm Deep Ceramic Composite aluminium dome tweeter, mounted in a purpose-designed Acoustic Lens Waveguide. This waveguide is not decorative, but intended to control dispersion and maintain stable imaging across a wide listening area.

Midrange and bass drivers are based on Micro Ceramic Composite and Deep Ceramic Composite cone materials, chosen for their stiffness-to-mass ratio. Driver sizes and configurations vary across the range, allowing each model to address specific room sizes and listening requirements, from compact setups to larger, more demanding environments.

Models in detail

Arcam Radia R15 – Compact precision

The R15 serves as the entry point into the Radia Speaker Series. As a two-way bookshelf speaker, it is designed for smaller rooms or space-conscious systems where accuracy and tonal balance take priority over sheer output. Its 130 mm Micro Ceramic Composite woofer works in conjunction with the DCC tweeter and Acoustic Lens Waveguide to deliver focused, controlled reproduction.

In practical use, the R15 is aimed at listeners who value clarity and spatial precision, particularly when paired with high-quality streaming amplifiers or Class-G designs.

Technical specifications

Arcam Radia R25 – Increased scale and depth

Building on the R15 concept, the R25 features a larger cabinet and a 165 mm woofer. This allows for deeper bass extension and higher dynamic headroom while retaining the precision of a two-way design. The R25 is particularly well suited to medium-sized rooms or compact home cinema systems where a separate subwoofer may not be required.

Technical specifications

Arcam Radia R35 – Floorstanding balance for living spaces

The R35 marks the transition into floorstanding designs. Its three-way configuration separates bass, midrange and treble duties to ensure consistent performance across a wide volume range. Three 130 mm woofers handle low frequencies, supported by a dedicated midrange driver for vocal clarity.

Rather than targeting extreme output, the R35 is designed for realistic living spaces, offering controlled low-frequency performance and precise imaging in both stereo and multichannel applications.

Technical specifications

Arcam Radia R45 – The flagship

As the flagship of the series, the R45 is designed for larger rooms and higher playback levels. Three 165 mm woofers, a dedicated midrange driver and the DCC tweeter form a three-way system focused on authority, stability and dynamic control. The R45 is intended for listeners who expect effortless reproduction, whether in stereo or home cinema configurations.

Technical specifications

Arcam Radia R35C – Center speaker for Home cinema

The R35C is designed as the tonal anchor of a multichannel system. Two 130 mm woofers flank the tweeter in its Acoustic Lens Waveguide, aiming for even dispersion and high speech intelligibility across the listening area.

Technical specifications

Arcam Radia R25B – Low-frequency foundation

The active R25B subwoofer completes the range. Its 250 mm driver is powered by a high-output digital amplifier and is intended to deliver controlled, extended bass for both stereo systems and multichannel setups.

Technical specifications

Price and availability

The Arcam Radia Speaker Series is scheduled to be available from the second quarter of 2026. Recommended retail prices are € 2.000,- for the R15 (pair), € 3.000,- for the R25 (pair), € 2.500,- for the R35 (each), € 3.500,- for the R45 (each), € 2.000,- for the R35C, and € 3.000,- for the R25B subwoofer.

Conclusion

With the Radia Speaker Series, Arcam does more than simply reintroduce loudspeakers into its portfolio. The new range represents a coherent, modern system concept that complements the Radia electronics while remaining open to a wide variety of HiFi and home cinema configurations. A shared technical foundation, clear model differentiation and consistent design language allow the speakers to be combined logically across different room sizes and applications.

At the same time, Arcam deliberately preserves the universal nature of classic loudspeaker design. The speakers are not dependent on specific electronics, yet offer added value when integrated into the broader Radia ecosystem. This balance between system integration and flexibility gives the Radia Speaker Series a distinct position in today’s HiFi and home cinema market, marking a considered and well-defined return to loudspeaker development.
