Cutting Wedge 2000® Acoustical Foam


CUTTING WEDGE 2000® installs to create seamless absorptive walls, and enhance imaging by reducing unwanted reflections.  The "2000" design enables you to increase thickness quickly by nesting layers instead of buying different and incompatible products. By adding 2 or 3 nested layers of CW2K, you can control energy hotspots in corners or in the path of first reflections quickly and efficiently. Cutting Wedge® makes creating virtual bass-traps in corners, using 3 or 4 nested layers of CW2K, simple and efficient.

  • Stackable to increase low frequency response

  • Prevent destructive specular reflections from distorting or coloring the sweet spot.

  • Eliminate room modes, comb filtering, standing waves and undesirable specular artifacts.

  • Attenuate sound pressure buildup at room boundaries (where walls meet walls).
