Invisible Speakers | Plastered-In Audio Within Seamless BASWA Ceilings

​

Arthur Acoustics provides specialist integration and certified UK installation of Invisible Speakers within BASWA seamless acoustic plaster ceilings and walls. By recessing flat-panel, acoustic-exciter loudspeakers directly into the BASWA panel plane and finishing seamlessly across the speaker diaphragm with microporous marble-sand plaster, your space enjoys immersive, room-filling audio and Class A reverberation control with zero visible grilles, trim rings, or hardware.

 

Why Architects and Audio Designers Integrate Invisible Speakers with BASWA

​

Traditional architectural speakers require cut-out holes, metal grilles, and visible bezels that interrupt clean ceiling lines—while bare hard surfaces still cause harsh echo that degrades audio clarity. Combining Invisible Speakers with BASWA acoustic plaster solves both visual and acoustic challenges in one cohesive surface.

  • 100% Concealed Architectural Finish. Loudspeakers disappear completely beneath the continuous BASWA marble-sand plaster plane, preserving unbroken ceilings and walls without grilles or shadow lines.

  • Superior Acoustic Clarity. Surrounding BASWA panels absorb up to 90% of disruptive room reflections, allowing your concealed audio system to deliver crisp speech, balanced midrange, and natural musical warmth.

  • Wide 180-Degree Sound Dispersion. Flat-panel invisible transducers radiate sound evenly across a broad hemispherical pattern, eliminating narrow "sweet spots" in open-plan living spaces, galleries, and commercial venues.

  • Compatible with Leading Invisible Audio Brands. Seamlessly engineered around premier plastered-in speaker systems including Sonance Invisible Series, Stealth Acoustics, Amina, and Nakymatone.

  • Choice of Smooth & Custom-Tinted Finishes. Finished cleanly in 0.7 mm Base, 0.5 mm Fine, or 0.3 mm Top marble plaster in crisp architectural white (~NCS S 0500-N) or custom RAL and NCS colours.

  • Protected by Thermal & Overload Safeguards. Installed with dedicated back-boxes, fire hoods, and DSP limiter protection to ensure reliable long-term performance and prevent plaster stress.

 

How Invisible Speaker Integration Works

​

Achieving an invisible, crack-free finish over an active loudspeaker requires precision coordination between your AV integrator and our accredited Arthur Acoustics craftsmen:

  • Structural & Cavity Coordination. During first-fix framing, dedicated acoustic back-boxes and fire-rated enclosures are mounted within the ceiling or wall void to control rear sound radiation and maintain fire compartmentation.

  • Flush Panel & Speaker Mounting. Our installation team fits the BASWA acoustic panels around the speaker housing, mounting the speaker face flush with the surrounding mineral wool or recycled glass board.

  • Reinforced Jointing & Precision Skimming. Perimeter joints are taped, grouted, and sanded completely level before applying the approved thickness of microporous BASWA marble plaster across the speaker diaphragm.

  • DSP Calibration & Acoustic Tuning. Once cured, your AV specialist calibrates the system using Digital Signal Processing (DSP) to compensate for the thin plaster layer, delivering transparent, high-fidelity sound.

 

Ideal Applications for Invisible Speakers & BASWA

​

Combining concealed audio with monolithic reverberation control makes this solution ideal for:

  • Luxury Private Residences & Open-Plan Living. Delivers effortless multi-room music and architectural purity across kitchens, dining spaces, hallways, and master suites.

  • Media Rooms & Discreet Home Cinemas. Conceals Dolby Atmos height channels and surround speakers seamlessly within dark or light BASWA ceilings.

  • Fine Dining Restaurants, Boutique Hotels & Spas. Fills hospitality spaces with warm background audio while keeping guests' conversations calm and intelligible.

  • Galleries, Museums & Executive Boardrooms. Preserves minimalist gallery ceilings while providing clear voice reinforcement and ambient audio.
