The VOID Acoustics Stasys 218 White is a high-output dual 18-inch passive subwoofer engineered for demanding large-scale touring and professional sound reinforcement applications. With 2400W AES power handling, output reaching 134dB continuous and 140dB peak, and an extensively refined 18mm birch plywood enclosure, it is built to deliver powerful low-frequency performance for festivals, concerts, arenas, and other high-output systems.
The VOID Acoustics Stasys 218 White is designed for large-scale systems where substantial bass output, durability, and controlled acoustic performance are required. Its two 18-inch low-frequency transducers use 4-inch voice coils and have been developed to deliver high power handling while maintaining the performance required for professional touring applications.
The enclosure has been extensively refined using resonance mapping to identify and control unwanted cabinet behavior. VOID Acoustics evaluated different cone and surround combinations, voice coil configurations, flux intensities, and out-of-band characteristics to develop a system optimized for demanding low-frequency reproduction.
With a frequency response of 32Hz to 200Hz ±3dB, 101dB 1W/1m efficiency, and 2400W AES power handling, the Stasys 218 is capable of reaching 134dB continuous and 140dB peak output. Recommended active crossover points range from 70Hz to 160Hz with a 24dB/octave slope, allowing the subwoofer to integrate into a variety of large-format sound reinforcement systems.
The cabinet is constructed from 18mm birch plywood and finished in textured TourCoat polyurea for durability in professional use. A perforated steel grille with foam filter protects the drivers, while dual 4-pole speakONâ„¢ NL4 connectors provide reliable system connections. Its performance and rugged construction make it particularly suited to festivals, concerts, arenas, touring systems, and high-output installations.
