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.Product Features\u003cbr\u003e\nBi-amp three-way loudspeaker system\u003cbr\u003e\nCompact trapezoid enclosure with very high output capability\u003cbr\u003e\nTriaxial Point Source configuration with user-rotatable mid\/high frequency horn\u003cbr\u003e\n15” (380mm)\/4” (100mm) voice coil, low distortion neodymium LF driver\u003cbr\u003e\n4” (100mm) HT polymer ring radiator\/1.4” (35mm) exit MF driver\u003cbr\u003e\n2.5” (64mm) HT polymer ring radiator\/1.4” (35mm) exit HF driver\u003cbr\u003e\n85° H x 50° V dispersion\u003cbr\u003e\nSupported by DISPLAY 3 software\u003cbr\u003e\nProduct Specifications\u003cbr\u003e\nType:  Bi-Amp 3-way (Passive MF\/HF) Loudspeaker\u003cbr\u003e\nFrequency Response (5):  54Hz-18kHz ± 3dB, -10dB @43Hz with preset\u003cbr\u003e\nDrivers\u003cbr\u003e\nLF: 15” (380mm) \/ 4” (100mm) coil neodymium motor\u003cbr\u003e\nMF: 1.4\" (25mm) exit \/ 4\" (100mm) coaxial HT polymer ring radiator\u003cbr\u003e\nHF: 1.4” (25mm) exit \/ 2.5\" coaxial HT polymer ring radiator\u003c\/p\u003e\n\n\n\u003cp\u003eRated Power\u003cbr\u003e\nLF: 800W AES, 3200W Peak\u003cbr\u003e\nMF\/HF: 110W AES, 440W Peak\u003c\/p\u003e\n\n\n\u003cp\u003eRecommended Amplifier:  iK42\/81 or VIA5002\/5004\u003cbr\u003e\nSensitivity (6):\u003cbr\u003e\nLF: 100dB\u003cbr\u003e\nMF\/HF: 109dB\u003c\/p\u003e\n\n\n\u003cp\u003eMaximum SPL (9) 129dB continuous, 135dB peak\u003cbr\u003e\nNominal Impedance\u003cbr\u003e\nLF: 8 Ohms\u003cbr\u003e\nMF\/HF: 8 Ohms\u003c\/p\u003e\n\n\n\u003cp\u003eDispersion (-6dB):  85˚ horizontal, 50˚ vertical\u003cbr\u003e\nCrossover:  650Hz\/4.8kHz\u003cbr\u003e\nEnclosure:  Birch plywood\u003cbr\u003e\nFinish:  Textured black finish\u003cbr\u003e\nProtective Grille:  Black perforated steel\u003cbr\u003e\nConnectors:  NLT4MPXX-BAG speakons (pair)\u003cbr\u003e\nPin Connections (Input):  LF : 1+ \/ 1- , MF\/HF : 2+\/2-\u003cbr\u003e\nPin Connections (Link):  1+ \/ 1-, 2+ \/ 2-\u003cbr\u003e\nFittings:  13 x M10 fixings, 4 x M10 Bracket Mounting Points and mTwo Handle Pockets\u003cbr\u003e\nDimensions:\u003cbr\u003e\n710mm (H) x 457mm (W) x 511mm (D) \u003cbr\u003e\n27.95ins (H) x 17.98ins (W) x 20.11ins (D)\u003c\/p\u003e\n\n\n\u003cp\u003eWeight:  35.6 kg \/ 78.48 lbs\u003cbr\u003e\nAccessories:  Portrait and landscape yokes (sold separately)\u003c\/p\u003e","brand":"Martin Audio","offers":[{"title":"Default Title","offer_id":58332913009014,"sku":"MAUTHS","price":4214.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0361\/2681\/files\/MAUTHS_Martin_Audio_THS_Image_1.jpg?v=1784913241","url":"https:\/\/spartanmusic.co.uk\/products\/ths-15-4-25-3-way-triaxial-trapezoidal-loudspeaker","provider":"Spartan Music","version":"1.0","type":"link"}
