    Description

    The VOID Acoustics Stasys 218 is a high-output, reflex-loaded passive subwoofer engineered to deliver extreme low-frequency performance for large-scale professional sound reinforcement systems, combining traditional acoustic principles with VOID’s advanced Stasys design philosophy. It features two custom-developed 18-inch low-frequency drivers with high-excursion 4-inch voice coils, delivering a combined AES power handling of 2400W and exceptional bass impact with clarity and control.

    To maximise performance, the 18 mm birch plywood enclosure has undergone the same advanced resonance mapping procedures applied across the Stasys low-frequency range. This process has driven material selection, internal bracing geometry and structural optimisation to minimise cabinet coloration, suppress destructive resonances and achieve maximum output from a lightweight yet highly rigid enclosure.

    Extensive transducer research and comparative testing underpins the Stasys 218 design, with detailed evaluation of cone materials, surround geometries, voice coil topologies and magnetic flux behaviour. These refinements ensure optimal integration with the reflex enclosure, delivering high efficiency, controlled excursion and clean low-frequency reproduction even at extreme output levels.

    The result is a state-of-the-art dual 18-inch subwoofer that combines advanced enclosure engineering with esoteric transducer performance and precision tuning techniques. Built for touring and permanent installations where uncompromising bass performance is required, the Stasys 218 stands as a flagship low-frequency solution from VOID Acoustics.
