Audison TH3.0II Thesis Line 3.0" Midrange Speakers

Description    
The human auditory system processes the range of medium frequencies with maximum sensitivity and selectivity because it makes the voice intelligible from the rest of the audio spectrum. The R&D team started from this simple principle to design from scratch the TH 3.0 II VOCE, dedicated to this fundamental range of frequencies, with the simple as well as ambitious target of extreme linearity, in order not to add or hide anything of the signal reproduced, enhancing in this way every nuance.

ULTRA HIGH CONTROL
The extremely powerful custom N38 H-grade Neodymium magnet ensures unmatched control of the mobile group and the aluminium ring nullifies the intermodulation distortion otherwise generated at peak excursions.

EXTREME LINEARITY
Through finite element simulation (FEM) the Audison R&D team has optimized the break-up point between cone/surround, obtaining an ultra-linear frequency response in the mid-range. The generous 30 mm CCAR (Copper Clad Aluminium Ribbon) voice coil wound with flat wire gives the TH 3.0 II Voce an extraordinary excursion and minimizes at the same time the cone non-linearity.

TPX CONE
TH 3 II Voce membrane is made of TPX, a transparent material that ensures frequency response linearity leaving the speaker interior in full view.
