Audison TH 6.5 II sax 165mm Woofer with Thesis Series Grille

TH 6.5 II SAX is a masterpiece of acoustic engineering, designed to guarantee extraordinary precision and transparency in sound reproduction. With a diameter of 165 mm, this woofer midrange has been developed to overcome the limits imposed by traditional designs, pushing sound performance to the highest levels without compromises.


The heart of the TH 6.5 II SAX is the powerful H-grade neodymium magnet, which generates an extremely stable magnetic field and extraordinary energy efficiency, essential for obtaining exceptional sound dynamics. The magnetic circuit design, optimized through advanced simulation software, focuses the magnetic field to maximize transducer efficiency, offering quick and precise response even in delicate midrange frequencies. Particular attention has been dedicated to the suspension system, a critical element for controlling cone movement. The spider, made of a mix of highly elastic fibers, allows linear excursion free from distortion even under intensive use conditions.

Similarly, the natural rubber surround is optimized to allow wide cone excursions without mechanically compressing the sound, preserving faithfulness to the original source. The 50 mm voice coil, wound with flat wire in CCAR (Copper Clad Aluminum Ribbon), not only maximizes the force factor, but also guarantees 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 constant audio quality, even during prolonged listening sessions. The aluminum alloy basket, designed to eliminate unwanted vibrations, further improves 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 a simple speaker: it is a concentration of technological innovation and refined design, created to offer an unprecedented sound experience. Every component has been carefully studied to minimize every form of distortion and compression, guaranteeing pure, detailed and incredibly faithful sound reproduction.

TH 6.5 II sax Features

  • 50 mm voice coil in CCAR (copper-clad aluminum ribbon) wound with flat wire to maximize force factor and heat dissipation.
  • Low voice coil inductance to optimize emission in the mid-high band (2-3 kHz).
  • N48 "H-grade" neodymium magnet with excellent thermal stability to guarantee optimal dynamic reserve in every situation.
  • Cone made of TPX®, a transparent material that reduces response irregularity in the mid-high range, leaving the internal speaker in full view.
  • Cone geometry designed using simulation software, to obtain regular emission at all listening angles.
  • Basket made in one piece of die-cast aluminum with four pairs of spokes to optimize heat transfer, eliminate turbulent air flows and guarantee maximum structural rigidity.
  • Hi-excursion suspension and spider, optimized with multi-physics behavior simulations of speakers.
  • eID technology that provides traceability of TH 6.5 II from the production phase to the owner.
