Audison's R\u0026amp;D team used finite element simulation software (FEM) to build a mathematical model, then produced the ideal transducer through extensive prototyping.\u003c\/p\u003e\n\u003cp\u003eThe TH K2 II P Coro is designed to transfer the musical output of Thesis electronics with absolute fidelity. The wide frequency extension of the TH 1.5 II (800Hz–22kHz) and the smooth mid-high response of the TH 6.5 II (up to 4kHz) give the user a broad crossover point range. Audison has designed two cut-off options to take advantage of this.\u003c\/p\u003e\n\u003ch2\u003eTH 1.5 II Violino\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e34mm CCAW single-layer voice coil — lightweight, stable at lower frequencies, no musical transient compression.\u003c\/li\u003e\n\u003cli\u003eCustom N38 \"H-grade\" neodymium magnet producing 1.67 T*m in the magnetic gap for strong dynamic response and low distortion.\u003c\/li\u003e\n\u003cli\u003eExclusive air-loading system gives a resonance frequency below 800Hz, allowing filter set-up from as low as 1.5kHz – 12dB\/Oct.\u003c\/li\u003e\n\u003cli\u003e38mm natural silk dome optimised using material characterisation, laser vibrometer scanning and Finite Element Analysis for a smooth, extended response.\u003c\/li\u003e\n\u003cli\u003eFrequency response up to 26kHz, optimised for off-axis installation.\u003c\/li\u003e\n\u003cli\u003eTH 1.5 II Violino Tuning System supports two electro-acoustic load types: bottom case or bottom disk, for best performance or flexible in-car integration.\u003c\/li\u003e\n\u003cli\u003eFull solid metal construction, with every part exclusively designed and produced for the TH 1.5 II.\u003c\/li\u003e\n\u003cli\u003eFEM-optimised faceplate and front spokes for improved dispersion pattern.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTH 6.5 II Sax\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e50mm voice coil in CCAR (Copper Clad Aluminium Ribbon) wound with flat wire to maximise force factor and heat dissipation.\u003c\/li\u003e\n\u003cli\u003eLow voice coil inductance to optimise output in the medium-high band (2–3kHz).\u003c\/li\u003e\n\u003cli\u003eN48 \"H-grade\" neodymium magnet with high thermal stability for consistent dynamic reserve.\u003c\/li\u003e\n\u003cli\u003eMagnetic geometry designed using FEM software to concentrate the magnetic field in the gap and maximise efficiency.\u003c\/li\u003e\n\u003cli\u003eTPX® transparent membrane reduces response irregularities in the mid-high band and leaves the speaker interior visible.\u003c\/li\u003e\n\u003cli\u003eMembrane geometry developed via simulation software for smooth off-axis emission.\u003c\/li\u003e\n\u003cli\u003eDie-cast aluminium single-piece basket with four pairs of spokes for heat transfer, turbulence reduction and structural rigidity.\u003c\/li\u003e\n\u003cli\u003eHi-excursion suspension and spider, optimised through multi-physical loudspeaker behaviour simulations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTHX 2 II\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-quality resistors, capacitors and inductors throughout — no compromises in construction.\u003c\/li\u003e\n\u003cli\u003eCompensation networks for both woofer and tweeter to optimise the load seen by the amplifier.\u003c\/li\u003e\n\u003cli\u003eCrossover filtering configured for a well-distributed vertical soundstage across the full height of the passenger compartment.\u003c\/li\u003e\n\u003cli\u003eFour tweeter emission levels (-4, -2, 0, +1.5dB) using the L-Pad technique.\u003c\/li\u003e\n\u003cli\u003eMid-frequency level control (-3 to 0dB) centred at 900Hz.\u003c\/li\u003e\n\u003cli\u003eBi-amplification option available.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Audison","offers":[{"title":"Default Title","offer_id":50637484785930,"sku":"90245","price":2499.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0745\/5431\/0922\/files\/audison-speakers-audison-thesis-th-k2-ii-p-coro-sax-violino-2-way-passive-component-kit-150w-rms-47168883097866.jpg?v=1748429072"}],"url":"https:\/\/www.cen.uk\/collections\/audison-thesis.oembed","provider":"CEN","version":"1.0","type":"link"}
