- Audison Thesis TH 6.5 II SAX is a masterpiece of acoustic engineering, designed to ensure extraordinary precision and transparency in sound reproduction. With a diameter of 165 mm, this midrange woofer has been developed to exceed the limits imposed by traditional designs, pushing sound performance to the highest levels without compromise. The heart of the TH 6.5 II SAX is the powerful H-grade neodymium magnet, which generates an extremely stable magnetic field and outstanding energy efficiency, essential for achieving exceptional sound dynamics. The design of the magnetic circuit, optimized through advanced simulation software, focuses the magnetic field to maximize transducer efficiency, offering a fast and accurate response even in delicate mid-range frequencies. Particular attention has been given to the suspension system, a critical element for controlling cone movement. The spider, made of a mix of highly elastic fibers, allows for a linear and distortion-free excursion even under intense use. Similarly, the natural rubber surround is optimized to enable wide cone excursions without mechanically compressing the sound, preserving fidelity to the original source. The 50 mm mobile coil, wound with flat wire in CCAR (Copper Clad Aluminum Ribbon), not only maximizes the force factor but also provides excellent heat dissipation, preventing overheating and ensuring stable performance over time. This technical detail contributes to the total absence of thermal compression, a crucial aspect for maintaining consistent audio quality, even during prolonged listening sessions. The aluminum alloy basket, designed to eliminate unwanted vibrations, further enhances sound clarity. Its structure, with a system of four pairs of spokes, not only offers great structural rigidity but also minimizes air resistance, avoiding aerodynamic compression phenomena that could affect midrange frequencies. In summary, the Audison Thesis TH 6.5 II SAX is much more than just a speaker: it is a concentrate of technological innovation and refined design, created to offer an unparalleled sound experience. Every component has been carefully studied to minimize any form of distortion and compression, ensuring a pure, detailed, and incredibly faithful sound reproduction.
