Construction and Core Materials

Each unit uses high grade cabinet plywood to form the internal structure. The insulation core consists of 4 lb mineral wool, which contributes to the panel’s sound absorption characteristics. The fabric wrapping covers the front and sides, while the rear is finished with a wood backing. This construction approach provides a rigid frame combined with a dense absorptive core suitable for fixed wall placement.

With an item weight of approximately 10.5 pounds, the panel has sufficient mass for secure wall mounting. The inclusion of easy-mount hardware supports direct installation onto drywall or other suitable wall substrates.

NRC Ratings and Frequency Data

The panel includes published NRC performance data across multiple frequencies. Reported NRC values are 0.22 at 125 Hz, 0.82 at 200 Hz, 1.21 at 500 Hz, 1.10 at 1000 Hz, 1.05 at 2000 Hz, and 1.05 at 4000 Hz. The product description also states a high NRC rated core of .95 or higher average. These figures position the panel as a broadband absorber intended to address reflections across low-mid to high frequencies.

The ASTM E84 Class A fire rating further identifies it as compliant with a recognized surface burning characteristics standard, making it appropriate for use in a range of interior environments where fire performance classification is required.

Intended Applications

The product description outlines a variety of practical applications. For home acoustics, suggested environments include foyers, grand rooms, man caves, living rooms, and home theaters. In studio acoustics, it is described as suitable for professional recording studios and home studios. Office acoustics applications include offices, lobbies, waiting areas, conference rooms, and break rooms. Restaurant acoustics applications reference diners, bistros, cafeterias, and eateries. Church acoustics applications include churches, mosques, synagogues, temples, and ashrams. It is also described for acoustic treatment in schools and gyms, including classrooms, multipurpose rooms, libraries, offices, lunchrooms, and gymnasiums.

These use cases reflect installation scenarios where echo control and reduction of reflected sound are priorities. Additional product information can be reviewed through this fabric-wrapped acoustic treatment panel page.

Installation and Handling

The panel includes mounting brackets and screws for wall installation. Reviews frequently mention ease of installation and reference included mounting brackets. Given its 10.5-pound weight and rigid wooden frame, proper anchoring into suitable wall material is required. The cabinet-grade frame and wrapped fabric surface are designed for fixed wall positioning rather than freestanding placement.

Customer-Reported Characteristics

Across multiple reviews, commonly repeated characteristics include improved room sound quality and reduction of echo. Customers frequently reference effectiveness in reducing reflected sound in offices, studios, and home theater environments. Quality of construction and appearance are also repeatedly mentioned, along with ease of installation and included mounting hardware. Some reviews reference the charcoal color as darker than product images indicate.
