The PURIFI PTT4.0M04-NAC-03 represents a significant advancement in midrange driver technology, offering audiophiles and system designers an unprecedented level of clarity and precision. This 4-inch ultra low distortion midrange driver is engineered to deliver exceptionally pure sound reproduction, making it an ideal choice for high-fidelity loudspeaker systems, studio monitors, and automotive audio installations where accurate midrange performance is paramount.
Designed for use in two-way or three-way configurations, this driver excels in applications demanding minimal coloration and maximum detail retrieval. Whether employed in a dedicated midrange enclosure or as part of a sophisticated multi-driver array, the PTT4.0M04-NAC-03 reproduces vocals and instruments with remarkable authenticity, revealing subtle nuances often lost with conventional drivers.
At the heart of this driver lies a robust aluminium cone membrane, chosen for its excellent stiffness-to-weight ratio and superior damping characteristics. The 101.6mm nominal diameter unit features a 6.85mm linear excursion (Xmax), enabling impressive dynamic range while maintaining control. With a total Q factor (Qts) of 0.28, this driver offers excellent transient response and seamless integration into sealed or vented enclosures. The 3.4-ohm DC resistance and 0.26mH voice coil inductance, combined with a CCAW voice coil, ensure efficient power handling and low thermal compression. Sensitivity is rated at 86.1dB SPL at 1m/2.83V, while the 73.5mm mounting depth facilitates flexible installation.
This PURIFI driver sets a new benchmark for midrange performance, delivering the transparency and low distortion demanded by the most discerning listeners.
