The PURIFI PTT4.0X08-NFC-01 is a 4-inch ultra low distortion long stroke driver engineered to deliver exceptionally clean, low-distortion bass in compact designs. This transducer represents a significant advancement in small-format audio, offering performance that belies its modest dimensions. It is ideally suited for high-fidelity subwoofer systems, nearfield monitors, and high-end automotive audio installations where space is at a premium but sonic accuracy cannot be compromised. Its linear excursion and controlled behaviour also make it an excellent choice for sealed and vented enclosures in critical listening environments.

Technically, this driver features a maximum linear excursion (Xmax) of 8.5 mm, contributing to a displacement volume (Vd) of 48.2 cm³, enabling substantial bass output from a small frame. The total Q factor (Qts) of 0.36, derived from a mechanical Q (Qms) of 4.3 and an electromagnetic Q (Qes) of 0.39, indicates excellent damping and transient response. An aluminium voice coil with a DC resistance (Re) of 7.1 ohms and low inductance (Le) of 0.53 mH ensures efficient power handling and minimal distortion. With a sensitivity of 82.3 dB SPL at 1m/2.83V and a mounting depth of just 78.5 mm, this driver integrates seamlessly into compact enclosures while delivering reference-grade bass performance.
