Tri-Trap is one of the most effective bass traps and takes up less space. Made from a solid core absorbent material, the triangular trap is an independent triangular prism that can hold up to 50 pounds of weight. The tri-trap cleaning, professional design means it does not need to be mounted on the wall or corners and is stackable for covering the bike. Tri-trap, like all GIK Acoustics bass traps, was tested in the laboratory of the renowned Riverbank sound and proved to be some effects at 50Hz and then. Effectively the tri-trap is designed to absorb the bottom end, but it also does a good job to absorb the high-end, smooth sound absorption from 50Hz to 5000Hz. Installing our tri-traps results in a decidedly balanced space suitable for even the most critical listener.
