Professional acoustic bass traps with bevel design and vinyl layer. 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 mix, songwriting, or rehearsal to build up in the corners of space. Ultimate Acoustics’ UA-BTBV is a professional bass trap that reduces the effects of standing waves in room, controlling and absorbing all that nasty rumble that gets in the way of hearing music accurately. With an elegant beveled finish, the UA-BTB looks every bit as great as it performs. UA-BTBV is sold in pairs and includes adhesives squares for applying them to the corners of room.
