What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.

Detail 01
Effective on mids and highs where echo and harshness live. Bass below roughly 250Hz mostly passes straight through.
Detail 02
Four square feet each, so 16 panels cover 64 square feet — roughly two walls of a small room at partial density.
Detail 03
Sits flush against walls and ceilings, unlike wedge or corner shapes. Easier to lay out in grids or checkerboards.
Detail 04
Enough for first reflection points, a ceiling cloud, and the rear wall in a bedroom-sized room.
Detail 05
Light enough to hang with adhesive or tabs; no wall anchors or framing needed. Also means it dents and tears if handled roughly.
Final check

Product questions
Straight answers to the questions shoppers most often ask about this product.
64 square feet total. In a small room that handles first reflections on both side walls plus a ceiling cloud, spaced rather than solid.
Not on its own. Two inches works on mids and highs. Boom comes from low frequencies, which need thicker corner traps.
Yes, they are light enough. Use adhesive rated for overhead use, and consider mechanical backup since gravity works against foam over time.
No. Spaced coverage at reflection points does most of the work. Full coverage makes a room sound dead and costs more.
