The room is part of the system.
Acoustic design, treatment and isolation for high-performance private cinema — from low-frequency control and first reflections to hidden fabric systems, HVAC noise and room-to-room sound isolation.
Great loudspeakers cannot correct a room that was never designed to let them perform.
Home cinema acoustics is not a shopping list of wall panels. Room dimensions, seating, loudspeaker geometry, low-frequency behaviour, decay, reflection paths, construction, HVAC and finishes are interdependent.
This site is built around that system-level approach: understand the room, model the risks, decide what must be absorbed, diffused, isolated or hidden, and only then select products and finishes.
Six parts of one acoustic system.
Explore the design process →Acoustic design
Room geometry, target decay, reflection strategy and integration before finishes are fixed.
02 · BassLow-frequency control
Modes, seat-to-seat consistency, subwoofer interaction and pressure-based treatment.
03 · TreatmentAbsorption & diffusion
Control early reflections and decay without simply making the room dead.
04 · IsolationSound isolation
Mass, decoupling, damping, doors, penetrations and flanking paths.
05 · IntegrationFabric wall systems
Acoustically transparent surfaces that hide speakers, treatment, cabling and service zones.
06 · NoiseHVAC & background noise
Quiet air movement, equipment noise and ventilation designed around a critical listening room.
Acoustic treatment and sound isolation solve different problems.
Treatment changes what sound does inside the cinema. Isolation changes how much sound passes between the cinema and the rest of the building. A room can be beautifully treated and still leak bass into bedrooms above it.
Bass is a room-scale problem.
Explore low-frequency design →Room modes
At low frequencies, wavelengths are comparable to room dimensions. The cinema develops pressure peaks and nulls that vary dramatically from seat to seat.
Subs + room + treatment
Multiple subwoofers, placement, delay/EQ and physical treatment are complementary tools. None should be treated as a substitute for understanding the room.
The best acoustic treatment does not need to look like acoustic treatment.
Stretched-fabric and acoustically transparent wall systems allow broadband absorption, diffusion, bass control, loudspeakers and cabling to sit behind a continuous architectural finish.
Local availability, without compromising independent specification.

Understand what the room is doing.
Open knowledge base →Room modes explained
Why bass changes from seat to seat — and what can actually be done about it.
02RT60 and decay
What reverberation time means in a small cinema and why one number is not enough.
03First reflections
When to absorb, when to preserve energy and how reflection control affects imaging.
04SBIR
Speaker Boundary Interference Response and why speaker distance from boundaries matters.
05Schroeder frequency
The transition between modal behaviour and the more statistical upper-frequency field.
06Baffle walls
Why the front wall can be part of the loudspeaker/acoustic design, not just a place to hang the screen.
Send the room before choosing the treatment.
Floor plans, room dimensions, speaker layout, screen position and construction information are enough to start a useful acoustic conversation.
