Invisible In-Wall Speakers for a Large Dubai Hills Living Room
A large villa in Dubai Hills Estate had an impressive recessed TV — but the sound was terrible. Rear-firing speakers bouncing audio off concrete walls left dialogue unclear and the room sounding flat. We replaced them with stealth plaster-over in-wall speakers driven by a Sonos amplifier, completely hidden in the walls.
Project Summary
Large open-plan living room. Recessed big-format TV with rear-firing speakers. Solution: stealth plaster-over in-wall speakers, plastered flush, driven by a Sonos Amp.
The Challenge
A stunning design feature — the recessed wall TV — had an acoustic flaw. The room was large, and the TV's speakers were rear-facing into the wall.
Rear-Firing TV Sound
When a TV is recessed into a wall, its built-in speakers fire backwards into the cavity and bounce off concrete. What reaches the viewer is muddy, indirect audio with no presence.
- Audio reflected off concrete
- No speaker directivity
- Weak dialogue clarity
No Visible Speakers Wanted
The client and their interior designer had invested heavily in a clean aesthetic. Visible speaker grilles, soundbars, or towers were explicitly ruled out.
- Zero visible hardware
- Clean wall architecture
- Premium interior design
The Solution: Stealth In-Wall Speakers
Plaster-over speakers installed into the wall, completely hidden after finishing, driven by a Sonos Amp for app-based control.
Stealth In-Wall Speakers
Stealth speakers are installed inside the wall cavity and then plastered over flush with the surface. No grilles, no visible hardware — the wall looks completely untouched.
- Plastered over flush
- No visible grilles
- Forward-firing directivity
Sonos Amplifier
A Sonos Amp drives the speakers and provides streaming control via the Sonos app — including direct TV audio input via HDMI ARC or optical.
- App-based volume control
- TV audio input supported
- Multi-room capable
The Results
Dramatically improved TV audio with zero visible hardware. The room sounds as good as it looks.
Acoustic Survey
Assessed the room dimensions and identified optimal speaker positions relative to the primary seating area.
Wall Installation
Cut apertures into the wall flanking the TV recess, installed speaker baffles and drivers inside the cavity.
Plastering & Finishing
Our plastering team finished the wall surfaces flush with the surrounding area and applied the final paint coat.
Sonos Integration
Installed and configured the Sonos Amp, integrated TV audio, and demonstrated app control to the client.

Why Recessed TVs Sound So Bad
The impulse to recess a large-format TV into the wall is understandable — it creates a stunning, gallery-like presentation. However, it creates an acoustic problem that most homeowners only discover after the renovation is complete and the wall has been plastered.
Almost all flat-panel TVs are designed to be wall-mounted or placed on a stand, with their speakers firing either downward, sideways, or backward relative to the viewer. When the TV is recessed into a deep wall cavity, those speakers are now inside a concrete box. The audio they produce bounces off the back and sides of the recess, and what reaches the viewer is a degraded, reflected sound with smeared transients and poor dialogue clarity.
In a large room — like the open-plan living area in this Dubai Hills villa — the reflected sound has to travel further to reach the primary seating. By the time it arrives, it has dispersed and lost energy. The client described the experience as "like watching TV in a cave." Dialogue was hard to follow, and turning up the volume only made the problem more pronounced.
The Stealth Speaker Technology
Stealth speakers — technically called "plaster-over" or "in-plaster" speakers — address this problem by flipping the acoustic equation entirely. Instead of working around a TV's rear-firing speakers, we install dedicated speaker drivers directly into the wall in the correct positions, with their cones firing directly at the listener.
The installation process involves cutting precisely sized apertures into the wall's plasterboard, inserting a speaker baffle that sits inside the cavity, and mounting the speaker driver into the baffle facing forward. Once installed, the wall is re-skimmed with plaster over the entire surface, including over the speaker membrane, and then painted. The speaker membrane is designed to vibrate through the plaster skin without cracking it.
The visual result is a completely unmarked, flat wall. There are no grilles, no covers, and no visible indication that speakers are installed. Even standing directly in front of the speaker location, most visitors cannot identify that anything is behind the wall.
Sonos Amplifier: Simple, Powerful Control
The speakers themselves are passive — they require an external amplifier. We selected the Sonos Amp as the driving unit for several reasons. First, it connects directly to the TV via HDMI ARC, meaning TV audio is automatically routed through the wall speakers whenever the TV is on. Second, the Sonos app provides straightforward volume and source control from any iPhone or Android device. Third, the system is inherently expandable — the client can add Sonos speakers in other rooms later without any rewiring.
The Sonos Amp was installed in a purpose-built cabinet in the AV area, connected to the in-wall speakers via concealed speaker cable runs that were routed during the installation phase before replastering. The entire system — TV on, volume adjusted, streaming music — is controlled from one app.
