TW030WA04 OEM only

TW030WA04 is identical to TW030WA02 with the exception that TW030WA04 is delivered without face plate.
TW030WA04 is a high performance 30mm soft dome tweeter that works equally well for most demanding high frequency audio applications.
The low resonance frequency and high power handling makes TW030WA04 the ideal tweeter for 2-way speakers, where standard tweeters will not do.
The usage of dual neodymium magnets as power house ensures an almost perfect magnetic screening for demanding A/V applications.
The low distortion and the smooth and extended frequency response combine extreme details and dynamics into making TW030WA04 the pearl of any high-end 2-channel system.
Small size and high efficiency make TW030WA04 well suited for high quality car applications.

FEATURES

TW030TU01 neo tweeter
  • Precision-coated textile diaphragm for improved consistency and high-frequency extension
  • 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
  • Build-in cavities under dome/edge to equalize pressure for lower distortion and lower resonance frequency
  • Rear heat sink for increased power handling and reduced power compression
  • Dual neodymium magnets for improved efficiency and improved magnetic shielding for A/V applications
  • High-stability ferro fluid for increased heat transfer from the voice coil
  • 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
