PURIFI PTT6.5M04-NFA-01 Mid-range Woofer

The PURIFI PTT6.5M04-NFA-01 Ultra Low Distortion Midrange represents a significant leap forward in audio driver technology, engineered to deliver exceptionally clear and natural midrange reproduction with vanishingly low distortion. This 6.5-inch driver is the ideal choice for discerning audiophiles and professional loudspeaker designers seeking to build high-fidelity multi-way speaker systems where midrange clarity is paramount.

Perfectly suited for use as a dedicated midrange driver in three-way or four-way loudspeaker designs, this unit excels in applications ranging from high-end home cinema to critical listening studio monitors. Its exceptional linearity and low distortion characteristics make it particularly effective in revealing subtle musical details and vocal nuances that lesser drivers would mask. Whether employed in a bookshelf speaker or a floor-standing tower, this driver delivers a remarkably open and transparent soundstage.

At the heart of the PTT6.5M04-NFA-01 lies a proprietary fibre-blend cone material, meticulously developed to provide optimal stiffness-to-mass ratio while effectively suppressing unwanted resonances. The motor system is engineered for exceptional linearity, with a total Q factor (Qts) of 0.33 and a sensitivity of 93.2 dB (SPL 1m/2.83V), ensuring effortless dynamics and high output capability. The 4-ohm impedance, combined with a low DC resistance of 3.9 ohms and a voice coil inductance of just 0.26 mH, guarantees excellent amplifier control and minimal phase shift. With a maximum linear excursion (Xmax) of 3.9 mm and a resonance frequency (Fs) of 55 Hz, this driver offers remarkable extension and control throughout the critical midband frequencies.

Combining cutting-edge engineering with meticulous construction, the PURIFI PTT6.5M04-NFA-01 sets a new benchmark for midrange performance, delivering an audio experience of unparalleled purity and realism.
