Rooms that know when to be quiet.

Acoustic panelling, diffusers, bass traps, and invisible ceiling treatments for homes, recording rooms, restaurants, boardrooms, and hotel public space. Measured, designed, built in our Marbella workshop, and installed by our own crew.

01 — What we solve

Most rooms ring. A few rooms listen.

Before · untreated

Flutter between parallel walls. Hard RT60 beyond 0.8 seconds. Every cutlery clink rides the cornice. Conversation gets loud because nobody hears themselves well.

After · tuned

Even absorption across 250 Hz – 8 kHz. Speech intelligibility climbs. Music decays cleanly. The room no longer competes with what's happening in it.

02 — System types

Four families. One for your room.

A.01

Fabric-wrapped panels

50 mm glass-wool core, frame-wrapped in chosen fabric. Our workhorse for cinemas, home theatres, and listening rooms. Drop-in replaceable covers. Wall or ceiling.

A.02

Slatted wood diffusers

Oak, walnut or ash slats over a PET-felt backing. Absorbs in the mids while diffusing high frequencies. Read as joinery — you don't recognise them as acoustics until you hear the room.

NRC 0.70Custom slat profile · hidden fix
A.03

Micro-perf plaster

Seamless acoustic plaster over backing layer. Invisible as a treatment — looks like a painted ceiling. Preferred for traditional architecture and heritage rooms.

A.04

Bass traps & tuned absorbers

Membrane and Helmholtz traps for the 40 – 250 Hz band that kills every untuned room. Hidden in soffits and riser walls. Calculated per room, not catalogued.

Common questions

Acoustic FAQ

More questions across all services on the full FAQ page.

01

Treatment or sound-proofing — which do I need?

Different problems. Treatment fixes how a room sounds from the inside (echo, harsh treble, boomy bass). Soundproofing stops sound leaking in or out. Most homes need treatment; a cinema or a recording room usually needs both. We'll tell you straight which your room actually needs after the site visit.

02

Will it look like a recording studio?

Only if you want it to. The panels can be slat-wood, stretched linen, microperforated plaster, or invisible behind an acoustic-transparent ceiling finish. We match the room's architectural language — most clients can't tell the treatment is there until they're told.

03

How do you decide where panels go?

We measure the room first — reverb time at six positions, frequency response, early reflections. That becomes an acoustic model. We then place absorbers at first-reflection points, diffusers at rear and side walls, bass traps in corners. You get the model and the placement drawing before we install anything.

04

Is there any fabric or finish we can't match?

Very little. The acoustic fabric is specified for transparency, not look — so the outer layer is your choice. We've done linen in 12 shades, three kinds of walnut, microcement-finish plaster, and one project in leather. If you send us a sample we'll tell you whether it works acoustically.

05

Do commercial spaces need something different?

Yes — and we separate the briefs. Restaurants, offices and hotel public spaces care about speech intelligibility, privacy between tables, and keeping the ambient level down. We design and certify to the room's intended use (noise class, reverb target) and issue a report on hand-over.
