AKUMAX Extra-Thick 0.7" Wood Slat Acoustic Wall Panels, 4 Pack 23.6" x 23.6", NRC 0.80 Sound Absorbing, Fire-Retardant, FSC-Certified, for Home Office, Studio & Living Room, Gray Oak — Open-Box, 66% Off

[TESTED NRC 0.80—REDUCE ECHO & REVERBERATION] Hard walls, ceilings and floors reflect conversations, TV audio, music and gaming sound, often creating distracting echo. With a tested NRC rating of up to 0.80, these wood slat acoustic panels absorb reflected sound for clearer, more comfortable room acoustics. Designed to improve sound quality within a room—not to completely block sound transmission through walls.

[BETTER ACOUSTICS FOR THE ROOMS YOU USE MOST] Create clearer video calls in a home office, improve dialogue in gaming rooms and home theaters, control excess reverberation in recording studios and music rooms, or soften everyday TV and conversation reflections in living rooms and bedrooms. The warm walnut finish also transforms a plain wall or ceiling into a modern architectural feature.

[EXTRA-THICK 0.7" 3-LAYER ACOUSTIC CONSTRUCTION] Each sound-absorbing panel combines 9 mm high-density PET acoustic felt, precisely spaced 9 mm E0-grade MDF slats and a refined walnut wood veneer surface. The slatted structure helps diffuse sound reflections while the thick felt backing absorbs acoustic energy. Made with tested fire-retardant components and FSC-certified wood-based materials for dependable indoor use.

[4 SQUARE PANELS—15.5 SQ FT TOTAL COVERAGE] Includes four panels measuring approximately 23.6 x 23.6 x 0.7 inches each. Arrange all four panels in a 2 x 2 layout to cover approximately 47.2 x 47.2 inches, or 15.5 sq ft. Consistent 26 mm slats, 14 mm spacing and 7 mm edge margins help adjoining panels form clean, continuous lines across the finished wall.

[CUT TO FIT—INSTALL ON WALLS OR CEILINGS] Cut the panels around corners, switches and outlets to suit your layout, then secure them using construction adhesive, suitable fasteners or both, depending on the mounting surface. Installation instructions are included. Each set is protected by a five-layer corrugated carton, corner guards and outer shrink wrap to help reduce transit damage. Adhesive and fasteners are not included.

This Siner Oak set includes four AKUMAX wood slat acoustic wall panels measuring 23.6 x 23.6 x 0.7 in each, for 15.5 sq ft of total coverage.
