British audio brand Arcam has re-entered the loudspeaker market, unveiling its new Radia Series at ISE 2026 in Barcelona.

The six-strong lineup includes two bookshelf speakers, two floorstanders, a centre channel and a powered subwoofer, designed for both high-end stereo listening and home cinema setups.

The Radia Series builds on Arcam’s five-decade audio experience, combining premium materials, modern cabinet design and extensive engineering support from HARMAN.

All speakers feature a 25 mm Deep Ceramic Composite (DCC) aluminium dome tweeter in an Acoustic Lens waveguide, paired with Micro Ceramic Composite (MCC) mid/bass drivers.

Cabinets are cross-braced for rigidity and finished in black walnut veneer with subtle yellow accents, creating a sleek yet understated look.

Integration is a key focus. When paired with Arcam’s SA35 or SA45 streaming amplifiers, or upcoming Radia AV products, speakers can be fine-tuned using the brand’s anechoic EQ system.

The floorstanding R35 and R45 and subwoofer R25B cater to larger setups, while the R15 and R25 bookshelves suit smaller spaces.

“Radia loudspeakers complement our electronics perfectly,” said Arcam Global Product Line Manager Mike Strange. “They’re flexible enough to work with any high-quality system but deliver extra performance when paired with our own amps.”

The Radia Series will arrive at authorised dealers in May. UK pricing ranges from £1,699 for the R15 pair to £5,998 for the R45 floorstanders, with international pricing pending.

Arcam also revealed a new Radia AV lineup (pictured below), including 8K-ready receivers, a 16-channel processor and power amplifiers, all supporting Dolby Atmos, DTS:X, Auro-3D and Dirac room calibration.
