Form At Wood Hexago CM-A (A04) – Hybrid Absorption + Diffusion Acoustic Panel

Form At Wood Hexago CM-A (A04) – Hybrid Absorption + Diffusion Acoustic Panel

Wooden acoustic panels from FORM AT WOOD are an excellent way to improve interior acoustics in a unique style. Acoustic panels effectively absorb sound and eliminate echo, creating a comfortable and aesthetic space. This series of HEXAGO acoustic panels were created in close partnership with specialists from the AGH University of Science and Technology in Krakow, as part of a R&D project. Shipping is a fixed all-in rate of $174 per panel (freight + import duties + customs processing; no post-delivery charges). Minimum order: 5 panels. Orders are non-cancellable once production begins and non-refundable except for transit damage or defect; damage must be reported within 48 hours with photos.

Highlights & Key Technologies

Designed to Absorb
HEXAGO CM-A acoustic panels have the highest sound absorption class A, in accordance with EN ISO 11654, providing broadband reverberation reduction and improved speech transmission. All acoustic properties are confirmed by R&D work under laboratory conditions. The hexagonal shape, natural materials and precise perforated surfaces ensure excellent sound absorption and original design of any interior, and the panel functions as both absorber and diffuser, with a diffusion range of 630-4000 Hz (acc to ISO 17497-2). The HEXAGO acoustic panel range won the DESIGN MASTERPRIZE award for its blend of design and acoustic performance.

The Star of Sound
Some rooms are built around listening. HEXAGO CM-A becomes the sculptural centerpiece that makes sound feel intentional — cleaner, closer, less tiring. Its tested and certified absorbing core makes it a natural fit for spaces where excellent sound quality is crucial, such as recording studios, home theaters, hotel lobbies, home cinemas, and conference rooms — any space where detail is everything.

Layered Acoustic Construction
Each panel is built as a compact modular hexagon with side length 250 mm: the top is an engineered perforated 3D FAW wall panel, the box is veneered wood and wood-based materials, and the core is absorbing wool and an acoustic membrane. Mounting is by freely hanging on screws, with a comprehensive mounting kit comprising a plug and hook included and four mounting holes on the back of each panel, for quick and easy DIY installation. Panels can be wiped with a dry microfiber cloth and polished with wood preservatives.

How Many Panels Do You Need
Based on FORM AT WOOD’s R&D, recommendations for reducing reverberation time are tested under real-world conditions: by a simplified calculation method, assume 7 HEXAGO panels per 10 m² of room area, scaled to the room size (10 m² → 7 panels; 12 → 9; 15 → 11; 20 → 15; 25 → 18; 35 → 25; 50 → 36; 75 → 54; 100 → 70). For spaces over 50 m², the quantity can be reduced by a maximum of 10% from the recommended amount while maintaining the optimal reverberation-reduction effect. Even a single HEXAGO panel improves room acoustics, but the recommended quantities ensure an audible difference; room acoustics are influenced by geometry, surfaces, materials, and glazing, so consulting an acoustics expert is worthwhile for a professional result.

Modular System Integration
The modular hexagonal construction can be mixed with HEXAGO CM-D panels and other FORM AT WOOD decorative panels like CARO MINUS and CARO, as well as other panels such as PET fiberboards, and combines seamlessly with its flat counterpart, the HEXAGO CM-A FLAT.

Wood Species & Tailored Finish
Available in European oak, American walnut, and ash, sourced exclusively from strictly managed, sustainable forests with every plank traceable to its source. Oak’s rich tannin content grants total mastery over color, with an essential palette of six stains: Snow White (C01), Silky Gray (C02), Black (C03), Natural (C04), Dark Brown (C05), and Nordic Raw (C06). A bespoke finishing service can match a supplied oil specification or physical flooring sample; raw, precision-sanded panels are available for on-site finishing workflows; and a varnishing service offers any shade from the RAL/NCS libraries. Due to the organic nature of timber, natural variations in grain, texture, and color are inherent characteristics and are not considered defects.
