TH 1.5 II violino

Tweeter | 200 W Peak Power | 38 mm | 6 ohm

THESIS

Transparency, a direct inheritance of the HV venti, is the principle that inspired the creation of Thesis speakers, born with the ambitious goal of giving voice to the pure musical message of Thesis electronics. The search for the best acoustic result was based on overcoming the intrinsic limits of traditional loudspeakers. Through a finite element simulation software (FEM) conceived by the Audison R&D team, a mathematical model was developed, which they used to create, with an intense prototyping activity, the ideal transducer.

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.
