TH K3 II A Orchestra system performance is far greater than the one achieved using individual Thesis components, reaching values of absolute excellence, going beyond the absolute.
TH 1.5 II Violino Tweeter
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.
TH 3.0 II Voce Midrange
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.
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.
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 Aluminum 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.
TH 3 II Voce membrane is made of TPX®, a transparent material that ensures frequency response linearity leaving the speaker interior in full view.
TH 6.5 II Sax Woofer
The TH 6.5 II Sax was born from a blank sheet with the aim of overcoming all the limits dictated by compromise-oriented design choices. This philosophy allowed us to obtain extreme performance and a design projected into the future, faithful to the inspiring principle of maximum transparency of the musical message.
The magnetic circuit uses a N48 “H-grade” Neodymium magnet that releases a very high quantity of energy and is ultra stable in temperature, ensuring an unparalleled dynamic. The geometry of the magnetic group has been optimized through a finite element simulation software to maximize efficiency by concentrating the magnetic field in the gap. A great deal of research has been carried out to reduce the modulation of the voice coil inductance by magnetically saturating the motor pole and using an aluminium short-circuit ring that also allows a greater extension towards the mid frequencies.
The development of the suspension system, a crucial element for each transducer, required a long research work: the development team created computational models to simulate every aspect of the multi-physical behavior of the loudspeaker. The spider was designed thanks to a long series of mechanical simulations performed to define its structure: a large elastic surface with 5 waves, ensuring an improved distribution of the elastic force; waves profile and gluing optimized to obtain the best symmetry in the voice coil and basket connection areas; spider composition made of a mix of two fibers to achieve the best elastic linearity, without mechanical compression effects even at high excursion levels.
Like the spider, the surround was also designed using mechanical simulations. The result is guaranteed by: use of natural rubber IIR; profile optimized to ensure wide excursion; maximization of linear elastic behavior without mechanical compression effects.
The 50 mm mobile coil in CCAR (Copper Clad Aluminum Ribbon), wound with flat wire to obtain a very compact winding, maximizes the force factor and at the same time allows for optimal heat dissipation.
The mechanical structure of the TH 6.5 II is a perfect combination of design and performance. The aluminium alloy basket incorporates all the components ensuring high precision in the various couplings. The structure featuring four pairs of spokes allows for solidity and damping of the vibrations offering very low resistance to the cone air flow. The wide spider distributes the elastic load optimally. A generously sized hole, protected by a filter cloth, prevents air compression phenomena under the spider, eliminating deleterious resonance at medium frequencies. The central opening in the bottom-plate ensures optimal decompression of the air column inside the voice coil and the output expanded material diffuses the turbulences and protects it from ingoing foreign bodies.
