Product Details
PURIFI PTT4.0X08-NFC-01 bass-midwoofer
PURIFI is a fresh company that designs and manufactures extreme high performance transducers and amplifier modules. Don’t let their freshness fool you; Their leadership team consists out of some well-respected audio technology pioneers. PURIFI developed a deep understanding of many performance degrading aspects for both amplifiers and transducers. Thanks to this understanding the PTT4.0X08-NFC-01 is on of the most potent 4” bass-mid woofers from our woofer category.
Besides this 8 ohm version, there is also a 4-ohm version and a 4" passive radiator available.
The challenge
Loudspeaker drivers are known to add a large, if not the largest, amount of distortion in 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.
A whole new take on driver design
PURIFI developed mathematical models for the motor system, suspension, dome and surround. These models allowed for optimization of each distortion mechanism separately. This systematic approach reduced all distortions mechanisms and keeps intermodulation distortion low. The result makes that the PTT4.0X08-NFC-01 is a compact 4” driver with unparalleled performance. This small driver is really up to big sound.
