Bang & Olufsen Beoplay A9 4th Generation (MK4) Wireless Speaker

The Beoplay A9 MK4 now comes with built-in Google Voice Assistant, allowing not only voice control of the speaker itself but also seamless management of other Google-enabled smart home devices. This generation also features a reengineered streaming platform for improved performance with Chromecast and other streaming services, enhanced Wi-Fi connectivity, multiroom support via Apple AirPlay 2, and Bang & Olufsen’s Adaptive Room Compensation technology.

Adaptive Room Compensation intelligently analyzes the speaker’s environment—taking into account room size, furniture placement, and acoustics—and uses a combination of built-in amplification and digital sound processing to optimize audio output. The result is a perfectly balanced, immersive listening experience tailored to the specific space, ensuring rich, clear, and detailed sound wherever the Beoplay A9 MK4 is placed.
