PURIFI PTT4.0M08-NAC-03 Mid-bass Woofer

The PURIFI PTT4.0M08-NAC-03 4" Ultra Low Distortion Midrange represents a significant advancement in audio engineering, delivering exceptionally clear midrange reproduction with vanishingly low distortion. This 4-inch driver is designed for discerning audiophiles and professional system builders who demand the highest levels of accuracy and transparency from their loudspeaker designs.

This mid-band subwoofer excels in a variety of applications, from high-end two-way and three-way loudspeaker systems to dedicated studio monitors and automotive audio installations. Its remarkable linear excursion of 13.7 millimetres allows it to handle substantial power while maintaining composure, making it ideal for both near-field listening and larger-scale sound reinforcement where precise midrange articulation is paramount.

At the heart of the driver lies an advanced aluminium cone, chosen for its exceptional stiffness-to-weight ratio, which effectively suppresses unwanted resonances and break-up modes. The motor system is meticulously engineered, featuring a low DC resistance of 5.6 ohms and a total Q factor of 0.32, ensuring tight, controlled bass and seamless integration with other drivers. With a sensitivity of 84.5 dB (SPL at 1m/2.83V) and a low voice coil inductance of 0.36 mH, this driver offers excellent transient response and minimal distortion across its operating range. The 101.6 mm nominal diameter and 74.5 mm mounting depth allow for flexible enclosure design, while the six-bolt fixing pattern ensures secure installation.

Combining cutting-edge materials with precision manufacturing, the PURIFI PTT4.0M08-NAC-03 sets a new benchmark for midrange performance, offering an unparalleled listening experience for those who refuse to compromise on sound quality.
