The IsoAcoustics ISO-200SUB Isolation Subwoofer Stands are designed for front and side firing subwoofers used in professional studios, project studios, HiFi, and home theatre settings. This stand is an updated version of the popular ISO-L8R series, featuring a lower profile, a new frame design, and an improved isolator for enhanced performance. The ISO-200SUB subwoofer stand measures 7.8" (200mm) wide x 10" (255mm) depth x 3.75" (95mm) height and is rated for subwoofers weighing up to 75lbs (34kg). It increases clarity, eliminates sympathetic vibrations, and provides tighter bass, leading to more punch and cleaner sound from your subwoofer. The stand is placed under a subwoofer to absorb rattling caused by plunging bass and is suitable for HiFi, entertainment systems, and studio use.
