The Cumulus is an acoustic panel designed to control sound reflections and reduce reverberation in critical listening environments such as recording studios, home theaters, and broadcast rooms. These triangular-shaped acoustic panels are designed to be mounted in the upper corners of a room, where sound reflections tend to accumulate. The panels are made from high-density glass wool, encased in an acoustically transparent fabric, providing effective absorption across a broad frequency range. The Cumulus panels enhance the overall sound clarity by reducing room echo and flutter.
