London Bass Trap

While the critical listening position is essential to focus on in room sound design, a well-documented scientific fact is that the most difficult frequencies to control are in the deep low bass region. This is due to the long wavelengths that require a lot of energy to produce, and then tremendous effort to control. These low bass frequencies tend to gravitate towards the corners of a room, where they get “stuck,” leading to frequency bumps in the room that cause the sound to change depending on where you are positioned.

The London Bass Trap kit is the perfect solution to this “too much bass” problem. Easily mounted in room corners, London Bass Trap kits use high-density glass wool panels to trap low frequencies as they enter, and try to exit, the room corner.
