The Stasys 118 is a single 18" reflex loaded low frequency enclosure build around traditional principles but designed with Stasys philosophy and attention to detail.

In order to extract the maximum performance from the Stasys 118 design, the heart of these enclosures was subjected to the same resonance mapping procedures as all other Stasys low frequency models. This practice has dictated the type of materials used around the enclosure, optimised the brace positioning and minimised destructive nodal conditions. All of this adds up to a structurally superior housing with minimum mass, the least possible amount of cabinet colouration and vastly increased output.

Exhaustive comparative transducer testing and evaluation led to the birth of a new 18” transducer with a high excursion 4” voice coil. The sonic properties of differing cone and surround combinations were studied, as well as differing coil topographies. Flux intensities and out of band abnormalities were also manipulated until the perfect combination was achieved. The marriage of a technologically advanced enclosure with esoteric transducer performance applied with superlative tuning techniques has resulted in a phenomenal package with state-of the- art performance that has well and truly left tradition behind.

High Impact Nightclub

Uppermost on any club designer's agenda is the creation an unforgettable aural and visual experience for today's brand-aware club goers, and therefore a truly state-of-the art sound system is essential to deliver that promise. Void Acoustics' Incubus loudspeakers not only push the boundaries of utmost fidelity and distortion-free sound levels, but also unmistakably radical aesthetics that enhance any interior.

Indoor / Outdoor Dance Events

In recent years, large dance music events have exploded in popularity. Attracting visitors means having the biggest DJs, brightest lights and of course the best sound systems which money can buy. A Void system will ensure that the audience never loses the impulse to dance and the experience is a pure connection with the music unlike any other.

Large Scale Touring

There’s a lot more to delivering great festival and arena sound to large audiences than just audio quality – truck pack, transportation and handling, reduced system size, ease and speed of rigging, optimally configured amplifier packages and intelligent processing – these qualities are found in abundance in Void’s tour sound loudspeaker systems.
