UA-BTBV Professional Acoustic Bass Traps with Bevel Design and vinyl covering – QTY 2. Let’s face it, most rooms were designed and built to house furniture and other box-type things. All that “squareness” provides the perfect environment for the low frequencies from your mix, songwriting, or rehearsal to build up in the corners of your space. Ultimate Acoustics’ UA-BTBV is a professional bass trap that reduces the effects of standing waves in your room – controlling and absorbing all that nasty rumble that gets in the way of you hearing your music accurately. With an elegant beveled finish, the UA-BTB looks every bit as great as it performs. UA-BTB is sold in pairs and includes adhesives squares for applying them to the corners of your room. Unique to Ultimate Acoustics is the addition of a thin layer of perforated vinyl covering that nearly doubles the performance of controlling lower frequencies while adding some measure of diffusion to higher frequencies.SpecsHeight: 24"Corner Bass TrapDesign Style:Bevel w/ VinylColor: Charcoal
