The Stillpoints Aperture is the only acoustical product that will give you both absorption and diffusion at the first reflection points of a system. And you want both! – The Aperture’s unique trapping system captures an area of wave form much broader than its small surface area would suggest. – The Aperture can be used to trap waveforms either facing the wall or, facing away from the wall. – The Aperture effectively increases soundstage width and depth. This is especially true for smaller rooms. (See the Michael Fremer review in Stereophile, Feb 2016.) – The Aperture will increase the dimensional perspective of the image structure. – The Aperture focuses music and voice without room boundary. The Stillpoints Aperture will NOT: 1. Decrease or limit the dynamics of the system. 2. Diminish the power of the bass attack. 3. Unevenly control one frequency over another. (This is often the case with traditional room treatments)
