RESONANCE CONTROL PANEL

Name: RESONANCE CONTROL PANEL
Brand: C-ATS
SKU: CA-RES-CP

A corner-loaded low-frequency absorber for room resonance.

Absorbs at low frequencies, where room modes make bass uneven from seat to seat.

Price on application

Time and labour saved: Whole-box quantities (4 per box, 1.44 m2). The ~300 mm layout tolerance does not transfer here: this panel's effectiveness depends on corner placement, so it is the one product in the range where position is not forgiving. State it rather than inheriting it.

What it replaces: Deep bass traps that consume corner volume the room cannot spare. Corner loading is what lets a shallow panel do work that would otherwise need far greater depth: the depth argument made concrete, and the product where it is most defensible.

Specification

How it works: Corner loading: placed where modal pressure is highest, so a shallow panel does work that would otherwise need far greater depth.
What it is for: Room corners and wall-to-ceiling junctions. The bass problem, which is the one dealers most often cannot solve.
What it is not for: Reflection control or general reverberation. Not isolation: resonance is a treatment problem, isolation is a different one entirely.
Limits: Effectiveness depends on corner placement. Away from a corner it is a much weaker device.

Measured absorption

BSRIA test 4, three items in corners against two walls (the manufacturer's intended configuration) BSRIA Report 100241/1

Scope of supply: 600 x 600 x 43 mm panel, 0.36 m2 each; 4 per box = 1.44 m2. Solid-surface front panel with machined countersunk fixing holes.
Boxes and coverage: Every box covers 1.44 m2. Quantities round up to whole boxes: a dealer buys full boxes.
Configuration: One size. The larger 600 mm format is deliberate: corner loading needs area.
Where it sits: Behind a stretch-fabric finish, concealed. Any fabric system works; Fabric Walls pairs well and is not a dependency.

What it needs from other trades: 4 x 3.5 x 60 mm bugle-head black drywall screws with threadless shank per panel; corner access; a fabric layer if concealed.

Test basis: BSRIA Report 100241/1, BS EN ISO 354:2003, BSRIA Bracknell, 210 m3 chamber. Tested 24 July 2019, reported 3 March 2020, free/unfixed mounting. Design-stage reference figures, not installed-effective values.
What is supported: Measured per-panel absorption with the corner configuration stated; BSRIA-tested 2019.
What is not claimed: Any modal-region figure below 125 Hz: the report does not extend there. No resonance numbers from the design tooling, which has a known blind spot below ~80 Hz.
