Description:

This tweeter is based on PTT1.3T04-HAG-01 delivering the signature crystal-clear sound PURIFI is known for, but featuring a 147mm waveguide optimised for directivity control matching 5" - 6.5" midranges or woofers (e.g. SPK16 reference design) whilst maintaining a super wide dispersion.

Features:

  • Wide-dispersion Waveguide with cooptimized, integrated Coherer
  • Negligible Force Factor Modulation (FFM) and Surround Radiation Distortion (SRD)
  • Extremely Low Magnetic Hysteresis Distortion (MHD)
  • High Sensitivity, high linear volume displacement
  • Designed and manufactured in Denmark
