Audison Thesis TH 6.5 II Sax - 6.5-inch Mid-Woofer for Precise Mid/Low Frequencies

The Audison Thesis TH 6.5 II Sax is a 6.5-inch mid-woofer that combines high dynamics with very clean midrange reproduction. Its neodymium motor, 50mm flat-wire voice coil, and TPX cone are designed for maximum control and resolution. With 150W continuous power at 4 Ohms and a linear operating range of 40 to 4500 Hz, it is ideally suited for high-quality 2- or 3-way setups – actively crossed over at around 2–3 kHz. At Carhifi.shop, you'll find the TH 6.5 II Sax as a powerful driver for detailed and precise reproduction.

Technical Highlights

• 50 mm mobile voice coil made of CCAR (Copper Clad Aluminum Ribbon), flat-wound for high force factor and efficient heat dissipation
• Low voice coil inductance for clean radiation in the upper midrange (2–3 kHz)
• N48 H-Grade Neodymium magnet with stable thermal reserves
• Magnet system geometry optimized by finite element simulation for maximum field concentration
• TPX cone for smoothing the frequency response in the mid/high range and clear visibility of the motor
• Flow-optimized, one-piece cast aluminum basket with high rigidity
• Hi-Excursion suspension and spider, multiphysically optimized
• eID technology for continuous traceability

Installation & Compatibility

With a nominal size of 165 mm and a cutout dimension of 143 mm, the TH 6.5 II Sax can be integrated into common 16.5 cm mounting locations. The mounting depth is 74.5 mm. The driver performs superbly in door and enclosure applications and benefits from a stable coupling to the vehicle frame. For its full potential, a powerful amplifier with 150 W RMS at 4 Ohms and an active crossover in the 2–3 kHz range (setup-dependent) is recommended.
