Wavecor TW022WA07 - 4 Ohm Dome Tweeter

TW022WA07/09 and TW022WA08/10 are true high-end tweeters designed for the
most demanding applications featuring an array of performance improving details
that participate in obtaining low resonance frequency, low distortion and very high
frequency extension

FEATURES
  • Precision textile dome ensuring extended response and very good consistency
  • 22 mm voice coil design with high power handling and low resonance frequency
  • Copper foil clad center pole yielding very low voice coil inductance for reduced distortion and icreased high frequency output
  • Vented through to a damped rear chamber for low resonance frequency and low distortion
  • Optimized light-weight dome for ultra high frequency cut-off, high effeciency, and improved transient response
  • Vented voice coil former for reduced distortion and compression
  • Copper-clad aluminium voice coil wire offering lower moving mass for improved efficiency and transient response
  • Built-in cavities under dome/edge to equalize pressure - for lower distortion and lower resonance frequency
  • Flexible lead wires for higher power handling and larger excursion
  • Gold plated terminals to prevent oxidation and ensure long-term reliable connection
  • Delivered with foam gasket attached for hassle-free mounting and secure cabinet sealing
