Innovative sound solutions
Despite its hidden nature, this speaker delivers dynamic, room-filling sound thanks to a powerful low-frequency driver and high-frequency transducers. An integrated crossover ensures a smooth, wide frequency response, providing clear highs and detailed mids.
The built-in back box minimises sound leakage into adjacent rooms and ensures consistent acoustic performance, while built-in protection circuitry (PTC) guards against overload and thermal damage, automatically resetting once safe conditions are restored. Perfect for living rooms, home cinemas, bedrooms and even commercial spaces, the Monitor Audio plaster in-wall speaker offers uncompromised audio with zero visual impact.
