TH 1.5 II Violino is an extraordinary tweeter featuring a 34 mm CCAW single layer voice coil combining light weight, stability at lower frequencies and total absence of musical transients compression.The extremely powerful custom N38 H-grade Neodymium magnet provides 1.67 T*m in the magnetic gap for superb dynamic response and very low distortion in the whole frequency range.The exclusive air-loading system resulting in a resonance frequency below 800 Hz, for filter set-up starting as low as 1.5 kHz 12dB/Oct. The 38 mm natural silk dome has been optimized with extensive material characterization, laser vibrometer scanning and Finite Element Analysis methods for a smooth and extended response. The frequency response is extended up to 26 kHz and is optimized for off-axis installation.The tuning System featuring two types of electro-acoustic load: bottom case or bottom disk according to targets of highest performance as well as flexibility of in-car integration.TH 1.5 II violino features a full solid metal construction structure with each part exclusively designed and produced for the Audison TH 1.5 II.The FEM (Finite Element Method) optimized faceplate and front spokes improve the dispersion pattern. Audison eID technology provides TH 1.5 II traceability starting from the manufacturing stage up to the owner. - From Audison Website
