Capable of 135dB peak, THS is an extremely powerful point source loudspeaker which combines very high output with extended frequency response. It is ideally suited to medium-scale club applications and installations which call for exceptionally high sound levels from a compact, standalone loudspeaker system.

Packing three high-technology drivers into a relatively small trapezoid enclosure, its innovative three-way triaxial configuration delivers enhanced output for its size and gives it the edge over comparable two-way systems in terms of superior mid and high frequency performance. Adding a compact Martin Audio SX subwoofer to extend low frequency output creates a dynamic, four-way setup with a small footprint.

To ensure the most effective use of amplifier count, THS is designed to be bi-amplified, with an internal passive network performing the mid/high crossover function.

The THS triaxial driver is a remarkable, state-of-the-art device. Its LF section comprises a reflex-loaded, high-specification 15” LF driver with a 4” coil, waterproof cone and neodymium magnet structure. A 4” midrange ring radiator and a 2.5” HF ring radiator, both with high temperature polymer diaphragms, are arranged coaxially at the rear of the LF driver and integrated into a 1.4” exit. This transitions through the magnet structure of the LF driver into an 85° x 50° horn. The horn itself is user rotatable, with a large mouth to maintain pattern control down through the midrange.

The durable birch plywood enclosure is finished in hardwearing textured paint and incorporates multiple threaded inserts to facilitate a variety of portrait and landscape mounting options — including eyebolt, yoke, pole and truss mounting. Twin handles assist installation and deployment. A steel grille with a triple-layer polyester backing protects the drivers and resists dust and water ingress.

Recommended amplifiers include Martin Audio iKON amplifiers with onboard DSP or VIA amplifiers used in conjunction with a DX4.0, DX0.6, or DX0.4 controller. THS systems can be modelled in 3D using DISPLAY 3 design and prediction software.
