Invisible Speakers: Hear Everything, See Nothing
Plastered into your walls and ceilings ā the ultimate in discreet audio.
What are invisible speakers?
Invisible speakers are flat-panel transducers designed to be installed behind plasterboard or drywall, then skimmed over with plaster. Once painted or wallpapered, they are completely invisible ā yet they produce full-range audio that fills the room.
The technology has been around for decades but has improved dramatically in recent years. Modern invisible speakers from brands like Amina, Stealth Acoustics, and Sonance can deliver genuinely impressive sound for background music, TV audio, and even home cinema surrounds.
How they work
Unlike conventional cone drivers, invisible speakers use exciters ā small devices that vibrate a flat panel. The panel itself becomes the speaker. Different panel materials (typically a specialised composite) are chosen for their acoustic properties.
The panel is mounted to the studwork, the plasterboard goes over it, and the whole surface is skimmed and finished. The speaker effectively becomes part of the wall.
Where they excel
- Period properties: Where wall-mounted or freestanding speakers would look wrong, invisible speakers preserve the aesthetic completely.
- Minimalist interiors: If the design brief is "nothing visible," invisible speakers are the only solution.
- Multi-room audio: Kitchens, hallways, bathrooms ā anywhere you want music without visible tech.
- Surround channels: Side and rear surround speakers in a cinema are often hard to place discreetly. Invisible speakers solve this elegantly.
Where they do not
Invisible speakers are not magic. They have limitations you should understand before specifying them:
- Bass response: Most invisible speakers roll off below 80ā100Hz. They need a subwoofer for full-range reproduction ā plan for one, possibly hidden under furniture or in a cabinet.
- Maximum output: They cannot match the dynamics of a high-end floorstanding speaker. For critical listening or large rooms, visible speakers still win.
- Placement constraints: They need a solid, flat surface. Curved walls, heavy wall hangings in front of them, or studwork issues can compromise performance.

Installation considerations
Installing invisible speakers is more involved than conventional in-ceiling or in-wall speakers. The plaster skim must be consistent and not too thick ā typically 2ā3mm maximum over the panel. Thicker plaster dampens the sound and reduces output.
Back boxes are usually required to isolate the speaker from the void behind and prevent sound transmitting to adjacent rooms. The back box also improves bass response by controlling the air volume behind the panel.
After installation, the speakers need a "running in" period of 20ā40 hours of music playback. The plaster and panel settle into their resonant characteristics over time. Do not judge sound quality immediately after installation.
The bottom line
Invisible speakers are the right choice when aesthetics are paramount and the primary use is background to moderate-level listening. For dedicated listening rooms or home cinemas where the front three channels carry the most information, a mix works well: visible left/right/centre for performance, invisible surrounds for discretion.
