C-ATS

The system

One system. Three problems solved.

Rooms are not improved by adding absorption until everything sounds dead. They are improved by controlling three distinct problems and balancing them across the whole space.

The three Rs of acoustics

One panel per problem

Resonance

Uneven bass, seat to seat

At low frequencies a room resonates. Bass is strong at some seats and absent at others, and no amount of loudspeaker choice fixes it. The Resonance Control Panel is corner loaded, including ceiling corners, because that is where modal pressure is highest. Consistent low frequency response is the foundation the rest sits on.

Reverberation

The wrong decay, or the wrong evenness

Reverberation is how long sound lingers. The goal is not simply less of it. It is the right decay time, and the same decay on every axis: length, width and height. The Reverberation Control Panel brings RT60 into the target window evenly, and is positioned around loudspeakers to guard against comb filtering as well as decay.

Reflection

Smeared imaging

Early reflections arrive at the listener just after the direct sound. They smear stereo imaging and cost clarity. The Reflection Control Panel is placed where reflections actually land, in a checkerboard layout, mirrored side to side, with each panel facing a gap, so imaging is protected at every seat rather than one.

Depth is the constraint, and it is the point

Acoustic treatment normally costs a room 100 mm to 200 mm or more on every treated wall. In a cinema or a listening room that floor area is worth more than the treatment. No panel in the C-ATS system is deeper than 50 mm, and the Resonance Control Panel is 43 mm, which is what makes the system usable in rooms that cannot spare the space.

Corner loading is how a shallow panel does low frequency work: placed where modal pressure is highest, it does what would otherwise need far greater depth. That is the depth argument made concrete rather than asserted.

How a project runs

Select, design, verify

  1. 01

    Select

    Start from a designed reference room. Each layout shows a panel package and where it goes for a room of that size, so the shape of the answer is visible before a design is commissioned.

  2. 02

    Design

    The design service models the room and returns a report and a treatment layout. Reflections are calculated for every loudspeaker and the combined resonance response for every listening position.

  3. 03

    Verify

    Once the room is built, its performance can be measured on site, so the targets the design set can be shown to have been met.

Isolation is a different problem

Isolation stops sound crossing the boundary between a room and the building around it. Treatment controls resonance, reverberation and reflection inside the room. The two are often confused and they are not interchangeable: isolation does not determine treatment performance, it provides the conditions in which treatment behaves predictably. Where a room needs both, they are specified separately.
