PURIFI PTT6.5X08-NFA-01

PURIFI PTT6.5X08-NFA-01 bass-mid-woofer 

PURIFI is a fresh company that designs and manufactures extremely high-performance woofers and amplifier modules. Don’t let the freshness fool you; Their leadership team consists out of some well-respected audio technology pioneers. PURIFI developed a deep understanding of many performances degrading aspects for both amplifiers and transducers. Thanks to this understanding the PTT6.5X08-NFA-01 is the most refined bass-mid woofer from our woofer category.

Besides this 8 ohm version, there is also a 4-ohm version and a 6,5" passive radiator available. Looking for similar performance, but something smaller? Take a look at the 4" PTT4.0W04.

Loudspeaker drivers are known to add a large, if not the largest, amount of distortion to an audio signal chain. Reducing this distortion is a challenge with the complication of fine-tuning to improve one part (e.g. harmonic distortion) often results in a degradation of another part (e.g. intermodulation distortion). These distortions consist out of several separate distortion mechanisms. By carefully mapping and completely understanding these mechanisms, PURIFI succeeded in improving the overall performance by a large degree.

PURIFI developed mathematical models for the motor system, suspension, cone, and surround. These models allowed for the optimization of each distortion mechanism separately. This systematic approach reduced all distortions mechanisms and keeps intermodulation distortion low. The result makes that the PTT6.5X08-NFA-01 is a compact 6.5” driver that parallels or even surpasses the bass performance of a low excursion, a large surface driver, while it also excels in midrange performance.
