The PURIFI PTT6.5M08-NFA-01 Ultra Low Distortion Midrange represents a significant advancement in audio engineering, designed to deliver exceptionally clear midrange reproduction with vanishingly low distortion. This 6.5-inch driver is the ideal choice for critical audio applications, including high-fidelity home theatre systems, studio monitors, and premium two-way or three-way loudspeaker designs where vocal clarity and instrumental accuracy are paramount.

Engineered for versatility, this mid-band subwoofer excels in both sealed and ported enclosures, offering a total Q factor of 0.38 for controlled, tight bass response. Its proprietary fibre composite cone ensures rigidity and damping, minimising breakup modes for a smooth frequency response. The driver features an 8-ohm impedance and a DC resistance of 6.5 ohms, with a sensitivity of 91 dB SPL at 1 metre for 2.83V, making it efficient even with moderate amplification. A maximum linear excursion of 3.9 mm and a resonance frequency of 57 Hz allow for dynamic, distortion-free performance across the critical midrange frequencies.

With an electromagnetic Q of 0.42 and a moving mass of 17 grams, this driver combines low mechanical losses with precise control. The equivalent volume of 12 litres and a nominal diameter of 165.1 mm make it a compact yet powerful solution for discerning audio enthusiasts seeking the highest standard of sound reproduction.
