IsoAcoustics adds to their award-winning line of isolation products with the Aperta Sub, an isolation stand designed for subwoofers weighing up to 80 pounds (36.3 kg). The Aperta Sub allows the listener to discover greater bass definition from their subwoofer with fewer complaints from their neighbors. The manufacturer explains that we are hard-wired to pick up bass rhythms more than other tones, and low bass frequencies allow the listener to feel a deep syncopated connection to their favorite music or movies. The large pulsating driver produces energy and vibrations that travel through solid structures that create issues in the listening space and can often be disturbing to others. Room treatment can be costly and doesn't mitigate structure borne-noises. Enter the Aperta Sub isolation stand that not only reduces these disturbances but also delivers better-sounding audio.
