Product Details
PURIFI PTT6.5X08-NFA-06 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-06 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.
