TW030WA06/08 with ferro fluid
30 mm chambered textile tweeter, 4/8 ohm

Real high-end tweeter design with extremely low resonance frequency and distortion.
Thanks to the extensive internal venting between three internal cavities no air inside is trapped. This feature extends the usable frequency range downwards to an extend very rarely found on tweeters.
Adding the high power handling this tweeter is the natural candidate for high-end 2-way speaker systems.

Key features:
  • Precision-coated textile diaphragm for improved consistency and high-frequency extension
  • Extreme internal venting through pole, voice coil former, and top plate to 3 internal chambers
  • Copper-clad aluminium voice coil wire offering lower moving mass for improved efficiency and transient response
  • Reflection-free rear chamber design with solid reinforcement ribs
  • Large ferrite magnet for improved efficiency and transient response
  • With or without high-stability light ferro fluid
  • Flexible lead wires for higher power handling and larger excursion
  • Black anodized magnet structure for increased power handling and reduced power compression
  • Gold plated terminals to prevent oxidation for long-term reliable connection
  • Delivered with EVA gasket attached for hassle-free mounting and secure cabinet sealing
