Two rooms can share the same loudspeakers, the same amplification and the same coverage targets, and still feel entirely different to be in. In one, conversation stays easy at full occupancy and the system seems to disappear. In the other, some tables are too loud, others feel detached, and every increase in level makes the room more tiring. The equipment is identical. The room is not, and the room is part of the system.
For architects and interior designers, this matters because most of what decides the outcome is fixed on the drawings long before a loudspeaker schedule exists: the finishes, the ceiling strategy, the geometry and the way the space will be used.
The room completes the system
A loudspeaker sends sound towards the listener, but much of what a guest hears has already interacted with a ceiling, a wall, a window or another guest. The balance between direct sound and everything the room returns determines clarity, comfort and how loud a space feels. A capable loudspeaker in an acoustically difficult room is still subject to that room, which is why audio design starts with the relationship between source, space and listener rather than with a product list.
Finishes decide how long sound stays
Glazing, stone, plaster and polished concrete reflect acoustic energy back into a room. Soft and absorptive finishes remove some of it; diffusive surfaces redistribute it. None of these is good or bad in itself. The question is whether the palette suits what the room has to do. A restaurant that trades on energy should not behave like a listening room, and a gallery, bar and reception in the same building may each need a different character. The finishes schedule is an acoustic document, whether or not it was drawn as one.
Geometry decides where the energy goes
Ceiling height, proportions, openings and changes in volume shape how sound spreads, so two rooms that look alike on plan can behave very differently in use. This is why loudspeaker positions cannot be set by symmetry or convenience alone. A position that sits neatly on the reflected ceiling plan can drive energy into a hard surface, or create a hotspot over one table while leaving the next disconnected. Position is an acoustic decision as much as a visual one.
Occupancy changes the room again
The empty room at commissioning is not the room guests experience. People, clothing and furniture add absorption; conversation, glassware and kitchens raise the background level. In hospitality, the room at the start of service and the same room three hours later are different acoustic environments.
At Claude's, the members' room beneath Chotto Matte in Soho, one system carries 40 seated covers and 120 people dancing in a basement directly beneath a working restaurant. That was solvable because we were appointed at RIBA Stage 2. Bass units could be placed on the floor plate furthest from the dining room above, and decoupled from the structure, before the ceiling and finishes were fixed.
Coverage is not comfort
Coverage plots, frequency response and headroom all matter, but a drawing showing even coverage does not prove a room will be comfortable. If too much reflected energy remains, speech loses definition even where coverage is even. If directivity does not suit the geometry, sound reaches surfaces it never needed to. If zoning ignores how the room trades, staff compensate with level instead of control. A system can meet its specification and still feel wrong.
Louder is rarely the answer
Selected work
Claude’s at Chotto Matte
Members’ room beneath Chotto Matte, Soho. One system for 40 seated covers and 120 dancing, appointed at RIBA Stage 2.
When a room becomes hard to hear in, the instinct is to turn the system up. Guests raise their voices to compete, the noise floor rises, and more level follows, until loudness is being used to fix a clarity problem. The better answer is control: of where sound is directed, of reflections, of low-frequency energy, and of zones as the room moves through its day.
What to resolve before specification
While the design is still on drawings, the design team can decide:
- where sound needs to originate, and which ceiling and wall areas must stay available for it
- which reflective surfaces are likely to cause problems, and where treatment can sit within the material scheme
- how loudspeaker positions coordinate with lighting, HVAC, sprinklers and joinery
- where low-frequency sources can be positioned with appropriate consideration for adjacent spaces
- which areas need independent zoning and control
- how containment and cabling reach each position cleanly
At Stage 2 or 3, each of these is a line on a drawing. At Stage 5, each becomes a compromise, usually a visible one. Where a project also needs formal acoustic assessment or compliance work, we coordinate with the project's acoustic consultant so both disciplines inform the same drawings.
The product still matters
None of this makes loudspeaker choice unimportant. Directivity, output, distortion, form and finish all matter, and the right product is what makes a design achievable, particularly where the loudspeakers are meant to be seen. But even the best loudspeaker cannot correct a room that asks it to do the wrong job from the wrong position. Product selection works when it follows the spatial strategy, not when it replaces one.
Designed as a room, not assembled from parts
The best audio environments are defined not by how much equipment they contain, but by how little conflict exists between the equipment and the space. When materials, geometry, loudspeaker behaviour and occupancy are treated as one problem, the technology recedes and the room simply feels easier to be in.
