Studiomaster Professional’s S9021 is a high-performance passive line array system engineered to deliver powerful sound, exceptional clarity and long-throw performance across demanding professional audio applications. Designed as a 2-way passive line array system, the S9021 integrates a single 12” RCF LF mid-bass driver with a 3” voice coil for detailed mid clarity, along with a 1” exit HF compression driver with a 1.75” voice coil for a clear and articulate high-frequency response. The system delivers 500W RMS and 1000W peak power, with a maximum SPL of 127dB.

One of the key highlights of the S9021 is its constant curvature waveguide, designed to provide array coherence and consistent dispersion across the listening area. With a coverage pattern of 120° horizontal and 9° vertical, the system delivers uniform acoustic coverage, while its state-of-the-art crossover design enhances frequency response for a balanced and powerful sonic performance. Variable splay angles of 0°, 3°, 6° and 9° provide flexibility in configuring arrays according to the requirements of different venues and applications.

Designed for efficient deployment, the S9021 features an integrated locking system that enables quick, safe and secure installation. Dual pole mounts offer multiple throw options, including straight and angled up-firing configurations, while a robust fly bar kit, available separately, facilitates quick rigging and flying for larger sound reinforcement applications. The system is equipped with two SpeakON input connectors for secure and reliable connectivity.

Housed in an acoustically tuned and durable wooden enclosure, the S9021 combines robust construction with a professional aesthetic. Its attractive speaker grille and anti-scratch textured paint finish provide durability while maintaining a clean and refined appearance. Meticulously tuned by Studiomaster Professional, the S9021 line array system is suitable for both demanding touring environments such as live events and DJ, and at permanent installations such as large venues.
