The PURIFI PTT6.5X08-NAA-08 Ultra Low Distortion Extended Woofer represents a significant advancement in mid-band subwoofer design, engineered to deliver exceptionally clean and accurate bass reproduction. This driver is the ideal choice for audiophiles and system builders seeking to achieve high-resolution audio with minimal coloration, making it perfect for use in dedicated subwoofer enclosures or as part of a multi-way loudspeaker system where precise mid-bass performance is critical.

Designed for demanding applications, this woofer excels in both home theatre and high-fidelity stereo setups, where its ability to produce tight, controlled low frequencies enhances the overall listening experience. Whether integrated into a sealed or ported cabinet, the PTT6.5X08-NAA-08 ensures that every note is rendered with remarkable clarity and authority, from subtle bass lines to powerful transients.

Technically, the woofer features an aluminium diaphragm that provides exceptional stiffness and damping, contributing to its ultra-low distortion characteristics. With a linear excursion of 9.8mm (Xmax), it can move significant air volume while maintaining control. The driver boasts a total Q factor (Qts) of 0.4, a resonance frequency (Fs) of 34 Hz, and a sensitivity of 85 dB (SPL 1m/2.83V). Its 4-ohm impedance and 5.9-ohm DC resistance (Re) ensure compatibility with a wide range of amplifiers, while the low voice coil inductance (Le) of 0.5 mH aids in extended high-frequency response.

This PURIFI woofer is a premium choice for those who demand the highest level of performance from their audio system, offering a perfect blend of engineering excellence and sonic purity.
