2" acoustic Studiofoam Pyramids treat small - to medium-sized areas including iso booths, control rooms and sound studios. They effectively kill standing waves and flutter echoes and, when used in conjunction with our LENRD or Venus Bass Traps or our Sunburst Broadband Absorbers, can effectively tame the full frequency bandwidth in virtually any acoustic environment.</p><p>2" Studiofoam Pyramids offer a bit of extra sound diffusion and slightly less sound absorption than 2" Studiofoam Wedges, so they yield a less dry-sounding space with a bit more "air."</p><p><strong>Available in Three different colors!!</strong><br />(Due to the variance of different computer monitors and video card color depth, Auralex Acoustics cannot guarantee that the color(s) represented on your computer screen will exactly match the foam products shipped. These color swatches are for reference purposes only.)</p>
