PURIFI PTT4.0X04-NFC-01 Bass-mid Woofer

The PURIFI PTT4.0X04-NFC-01 represents a significant leap forward in compact driver engineering, offering an ultra low distortion long stroke design that redefines expectations for a 4-inch transducer. This remarkable unit is engineered to deliver exceptionally clean mid-bass and subwoofer performance, making it an ideal choice for high-fidelity audio systems where accuracy and clarity are paramount.

This driver excels in a variety of demanding applications, from high-end two-way bookshelf speakers to dedicated subwoofer systems in compact enclosures. Its exceptional linear excursion and low distortion characteristics make it particularly suited for near-field monitoring, home theatre setups, and audiophile-grade multi-channel systems where precise bass reproduction is critical. The driver's ability to maintain composure at high output levels also makes it an excellent candidate for active crossover designs.

Technically, the PTT4.0X04-NFC-01 boasts a maximum linear excursion of 8.8mm, contributing to a displacement volume of 48.2cm³. With a sensitivity of 84.5dB SPL at 1m/2.83V and a total Q factor of 0.3, this driver offers excellent control and transient response. The low DC resistance of 3.8Ω and voice coil inductance of 0.38mH ensure efficient power handling, while the mechanical and electromagnetic Q values of 4.5 and 0.32 respectively indicate a well-damped, accurate performer.

In summary, the PURIFI PTT4.0X04-NFC-01 sets a new benchmark for compact, high-performance drivers, delivering audiophile-grade bass and mid-bass reproduction in a remarkably small footprint.
