PURIFI PTT8.0X08-NAB-01 Mid-range Woofer

The PURIFI PTT8.0X08-NAB-02 Mid-range Woofer represents a significant advancement in compact bass reproduction, engineered to deliver deep, controlled low frequencies without compromising on precision. This high-excursion driver is ideally suited for use in sealed and ported enclosures where space is at a premium, making it an excellent choice for high-end home audio systems, studio monitors, and custom automotive installations where accurate mid-bass performance is paramount.

At the heart of this woofer lies an aluminium diaphragm, chosen for its exceptional stiffness-to-weight ratio, which ensures pistonic behaviour and minimises distortion even at high output levels. With a generous linear excursion (Xmax) of 9.3mm and a displacement volume (Vd) of 218.6, the driver can move substantial air while maintaining control. The motor system is characterised by a low total Q (Qts) of 0.35, combining a mechanical Q (Qms) of 5.8 with an electromagnetic Q (Qes) of 0.37, resulting in a well-damped response ideal for accurate transient reproduction. The voice coil exhibits a low inductance (Le) of 0.33mH and a DC resistance (Re) of 6 ohms, contributing to a sensitivity of 86.4dB (1m/2.83V). The 203.2mm nominal diameter driver requires a cut-out diameter of 193mm and has a mounting depth of 108.5mm, with six fixing holes on a 221.3mm frame. This PURIFI woofer delivers authoritative, low-distortion bass that integrates seamlessly into discerning audio systems.
