PURIFI PTT5.25X08-NFA-01 Mid-range Woofer

The PURIFI PTT5.25X08-NFA-01 Mid-range Woofer represents a significant advancement in audio engineering, designed to deliver exceptionally precise mid-bass reproduction with remarkable clarity. This 8-ohm driver is ideally suited for high-fidelity audio systems, home theatre setups, and professional studio monitors where accurate sound reproduction is paramount. Its capabilities make it particularly effective in two-way or three-way speaker designs, serving as a dedicated mid-band subwoofer that bridges the gap between lower frequencies and higher-range drivers.

At the heart of this driver lies a proprietary fibre blend cone, meticulously developed to minimise distortion while maintaining structural rigidity. The 133.4 mm nominal diameter driver achieves a linear excursion of 9.8 mm, enabling it to handle substantial power without compromising sound quality. Technical specifications include a sensitivity of 84.7 dB SPL at 1m/2.83V, a total Q factor (Qts) of 0.26, and a DC resistance (Re) of 3.8 ohms. The voice coil utilises CCAW (Copper-Clad Aluminium Wire) for optimal conductivity and thermal management, with an inductance (Le) of 0.55 mH. The driver’s mechanical losses (Rms) are rated at 0.59, contributing to its controlled and accurate performance. With a mounting depth of 82.5 mm and six mounting holes on a 121.5 mm bolt circle, this PURIFI woofer integrates seamlessly into precision-engineered enclosures, offering audiophiles and designers a truly exceptional component for reference-grade sound systems.
