Dark Chestnut Square-Slat Acoustic Wall Panels, Soundproofing for Walls 104.375 x 11.25 -- 2 Pieces per Box

Dark Chestnut Square-Slat Acoustic Wall Panels, Soundproofing for Walls 104.375 x 11.25 -- 2 Pieces per Box

Deep, Rich Dark Chestnut in a Bold Square-Profile Slat -- Three-Dimensional Depth with Dramatic Shadow Definition

Transform any interior wall or ceiling with the Dark Chestnut Square-Slat Acoustic Wall Panels -- a premium soundproofing panel that delivers a deep, warm chestnut brown finish in a thick, square-profile slat that adds real depth and dimension to the surface. Where flat slat panels cast subtle shadow lines, the square slat profile creates bold, architectural ridges -- each slat stands fully proud of the felt backing, with visible depth on the top face and a dramatic shadow channel between each one. In Dark Chestnut, those shadow channels read almost black, making the contrast between slat and gap sharper and more defined than on lighter finishes.

At 11.25" wide with two panels per box, this is the panel to choose when you want a strong, grounded presence on the wall -- the kind of surface that anchors a room rather than brightens it. Dark Chestnut works particularly well in spaces with warm ambient lighting, where the rich wood grain and deep shadows combine to make the wall feel both sophisticated and alive.

Order a sample first to confirm the tone works in your space. Wood veneer finishes vary under different lighting conditions -- seeing it in person before ordering full boxes is always the right call.

Built to Improve Your Space -- Acoustically and Aesthetically

These panels are engineered to address two problems at once: sound quality and interior design. The high-density acoustical felt backing absorbs sound reflections, reduces echo and reverberation, and helps contain noise within a room. Meanwhile, the Dark Chestnut wood veneer slats create a rich, warm surface that adds genuine architectural depth -- not just surface texture -- to any wall.

• Reduces echo and reverberation -- improves speech intelligibility and audio quality
• Contains noise within a room -- increases privacy in offices, studios, and meeting spaces
• Diffuses sound waves through the slatted panel geometry
• Felt backing produced from recycled material

Dark Chestnut in the Square Slat Format

Dark Chestnut is one of the most dramatic finishes in the lineup, and the square slat profile makes it even more so. The deep chestnut brown -- rich, warm, and full of natural grain variation -- stands in sharp contrast against the dark felt gaps between each slat. In raking light, the square-profile ridges cast long, defined shadows that shift as the day progresses, giving the wall a dynamic quality that flat-panel treatments cannot match. This is the right finish for rooms that need weight and presence: a home theater where you want the walls to recede and absorb, a recording studio where both acoustics and aesthetics matter, or a living room feature wall where you want the surface to feel like a piece of the architecture rather than a decorative layer.

Installation

Installation is straightforward and requires only basic tools. Panels can be installed three ways:

• Glue-down: Apply construction adhesive directly to the felt backing and press firmly to the wall surface.
• Screw-down: Drive screws through the felt backing into the wall or ceiling framing between slats.
• Batten mount: Install horizontal wood battens on the wall first, then screw panels to the battens for a raised installation.

Panels can be installed horizontally or vertically, and cut to length with a standard miter saw or circular saw. For walls taller than the panel length, stack panels and offset the seams on each row by half a panel -- the result mimics a classic hardwood flooring H-pattern and is virtually seamless.

Frequently Asked Questions

Q: What is the Dark Chestnut finish?

A: Dark Chestnut is a deep, rich warm brown -- darker and more saturated than walnut, with visible wood grain character that adds natural variation across the panel surface. It reads as grounded and sophisticated in most interior palettes, pairing well with charcoal, cream, terracotta, and muted earth tones.

Q: How does the square slat differ from the flat slat versions?

A: The square slat profile adds genuine physical depth to the wall surface. Each slat stands fully proud of the felt backing -- you see the top face of every slat, and the gaps between them are deep shadow channels rather than shallow grooves. The flat slat versions sit flush on the backing with V-shaped grooves between slats. The square slat is bolder, more three-dimensional, and creates more dramatic shadow definition, especially under directional or raking light. Acoustic performance is comparable across all formats.

Q: How does this compare to the Dark Chestnut flat-slat panel?

A: Same finish, same dimensions, same acoustic performance -- the only difference is the slat profile. The flat-slat version creates a refined, linear texture flush with the panel surface. This square-slat version projects fully from the backing for a bolder, more architectural three-dimensional look. If you want the Dark Chestnut tone with maximum visual impact and depth, this is the version to choose.

Q: Do these panels actually reduce noise?

A: Yes. The high-density acoustical felt backing is engineered to absorb sound reflections, reduce echo and reverberation, and help contain noise within a room. These panels improve the acoustic experience of a space without blocking all sound transmission through walls entirely.

Q: Are these panels real wood?

A: The slats are MDF (medium-density fiberboard) wrapped in a premium wood veneer finish -- real wood on the surface, engineered core for stability and acoustic performance.

Q: Can these be installed on ceilings?

A: Yes. Screw or batten mount is recommended for ceiling applications -- drive fasteners into solid framing. Glue-down alone is not recommended overhead.

Q: How much does each box cover?

A: Each box contains 2 panels at 104.375" long x 11.25" wide, covering 16.3 sq ft per box. Add 10% for cuts and waste when estimating your total order.

Q: Is there a minimum order?

A: 15-box minimum. A $2.99 sample swatch is available before committing to a full order.

Q: Is free shipping included?

A: Yes -- free shipping within the contiguous United States.

Q: Do you have a showroom?

A: Yes -- 10926 Woodside Ave Suite A, Santee, CA 92071. Monday-Friday, 8am-4pm.
