This 10.0" is a member of the ultra low distortion extended-stroke woofer family from PURIFI. The driver incorporates the easily recognizable PURIFI NeutralSurround suspension and ultra-linear
PURIFI PureDrive
motor system working in concert to enable record-breaking linearity specifications over an extended bandwidth.
The PTT10.0X04-NAB-01 features:
Vibroacoustic optimized cone and dust cap in black anodized aluminum
Negligible Force Factor Modulation (FFM) and Surround Radiation Distortion (SRD)
Ultra Low Magnetic Hysteresis Distortion (MHD)
"Real" long-stroke performance with distortion remaining low over full excursion
Designed and manufactured in Denmark
