This is a 4-pack of 2-inch thick red acoustic foam pyramid panels. They are 12x12 inches in size. These panels are a great addition to any recording or listening space. They work by absorbing unwanted reflected noise and echo during recording, playback, and mixing, which significantly improves the acoustics of the room. Ideal for podcasting, broadcasting, streaming, home studios, drum rooms, control rooms, vocal booths, rehearsal spaces, and similar applications. The 3D pyramid design offers a large surface area for maximum sound absorption. With an acoustical performance rating of 0.45 NRC and a Class A flammability rating (under ASTM - E84 testing standards), they are both effective and safe. Each single piece measures 12/305mm (L) x 12/305mm (W) x 2/51mm (H) and weighs 0.13 lbs./0.06 kg.
Using these acoustic pyramid panels is easy. Just find the areas in your room where sound reflection is a problem, like near speakers or in corners. Peel off the backing (if it has one) and stick the panels to the wall. If they don't have adhesive, you can use mounting tape or other appropriate wall - hanging methods. When using them in a home studio, place them around your recording equipment to get the best sound quality. For drum rooms, cover the walls to reduce echo. As for maintenance, keep them clean by gently vacuuming them every few months to remove dust. Avoid getting them wet as it can damage the foam. If they get dirty, you can spot - clean them with a mild soap and water solution, but make sure to dry them thoroughly. Also, keep them away from open flames because of their foam material, even though they have a good flammability rating.
