TOTAL TRANSPARENCY 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. MAXIMUM LINEARITY, MINIMUM INDUCTANCE, EXCELLENT VENTILATION 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. TOTAL ABSENCE OF MECHANICAL COMPRESSION 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.
