ARCAM Brings Dirac Live Active Room Treatment to the Acclaimed Radia Series for Next-Level Home Cinema Performance
The new ARCAM Radia AVA15, AVA25, AVA35 and AVP45 will support Dirac Live Active Room Treatment, unlocking advanced system-wide acoustic optimization for high-performance home theaters.
Barcelona, February 3, 2026
Swedish digital audio pioneer Dirac today announced that Dirac Live Active Room Treatment (ART) will be available on ARCAM’s new lineup of Audio Video Amplifiers (AVA) in the Radia Series, including the AVA15, AVA25, AVA35 audio video amplifiers and the AVP45 16-channel processor. The new ARCAM Radia AV models will make their global debut at ISE 2026 in Barcelona, at the HARMAN Luxury Audio booth (2F150).
The new AV models expand the Radia Series into home cinema and will support Dirac Live Room Correction – with Dirac Live Bass Control and Dirac Live Active Room Treatment available as optional upgrades – to deliver a comprehensive smart acoustics solution for discerning home theater enthusiasts and professional integrators.
“ARCAM has long been recognized for delivering sound that honors the integrity of the original recording,” said Fredric Tapper, Dirac’s Vice President and Head of Business Development. “With Dirac Live Active Room Treatment coming to the Radia Series AV models, ARCAM customers will be able to experience a new level of low-frequency precision, clarity, and immersion. Together, we’re enabling home cinema systems to perform at their full potential, regardless of room constraints or speaker layout.”
First introduced in 2023, Dirac Live ART transforms a system’s existing speakers and subwoofers into a cooperative acoustic control network that actively manages low-frequency resonances and reflections. Powered by Dirac’s patented MIMO (Multiple-Input, Multiple-Output) technology, ART enables every speaker in the system to work together to control bass behavior across the room.
Rather than treating each speaker as an isolated source, Dirac Live ART coordinates them as a unified system to reduce decay times, smooth bass response, and improve timing and coherence throughout the listening area. The result is tighter, more articulate low-end performance, enhanced dialogue clarity, and a broader, more consistent sweet spot – even in asymmetrical or acoustically challenging rooms.
“Dirac Live Active Room Treatment gives users and integrators a powerful way to take system performance further when room acoustics demand it,” said Nilo Casimiro Ericsson, Product Management at Dirac. “By enabling the entire speaker system to work together, ART helps deliver tighter bass, improved clarity, and more consistent results across any listening space.”
Dirac Live ART builds on Dirac Live Room Correction, which optimizes both magnitude and phase response to address acoustic issues traditional EQ cannot resolve, and Dirac Live Bass Control, which uses machine learning to co-optimize subwoofers and speakers for consistent low-frequency performance across multiple seats. Together, these technologies form Dirac’s most advanced home theater optimization platform to date.
“The Radia Series has already resonated strongly with customers for its musical performance and distinctive design,” saidJames Todd, Senior Global Product Line Manager for ARCAM at Harman. “Bringing Dirac Live Active Room Treatment to our first Radia AV models ensures that music, movies, and immersive formats are reproduced with exceptional control, depth, and realism in real-world living spaces.”
The ARCAM Radia AVA15, AVA25, AVA35 and AVP45 will be available beginning in Q3 2026, with Dirac Live ART available as an upgrade.

About ARCAM
ARCAM is based just outside the historic university city of Cambridge. Its story began in 1976, when two friends, both studying engineering at the university, bonded over a shared passion for music and electronics and founded Amplification and Recording Cambridge.
Since then, ARCAM has been at the forefront of high-quality audio. The company has been designing and making CD players for almost 30 years and expanding its amplifier legacy for nearly 50 years. In 1995, ARCAM moved into home cinema electronics, earning a world-class reputation for some of the best-sounding AV equipment. Demonstrating its engineering expertise, the company also developed its DVD and Blu-ray players from scratch in the UK, applying decades of CD player experience to ensure they delivered music and movies with equal fidelity.
ARCAM’s expertise lies in preserving delicate signals and reproducing music with all its subtleties and excitement intact. As audio moves into ever-higher-definition formats, ARCAM remains committed to faithfully serving the music and maximising enjoyment for listeners.
ARCAM is a brand within the HARMAN Luxury Audio Group, a lifestyle division of HARMAN International, which is a wholly-owned subsidiary of Samsung Electronics Co., Ltd.
