More info

TW030WA11 and TW030WA12 are tweeters designed for the most demanding applications, where low resonance frequency, high sensitivity and power handling, controlled dispersion, and a very wide frequency range are required.

  • Featuring waveguide face plate for controlled dispersion, offering optimized off-axis and power response
  • 30 mm voice coil design with high power handling, and low resonance frequency
  • Copper clad center pole yielding very low voice coil inductance for reduced distortion and increased high frequency output
  • Internal volumes for low resonance frequency and distortion
  • Precision-coated textile diaphragm for improved consistency and high-frequency extension
  • Optimized dome shape for ultra high frequency cutoff
  • 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
  • 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 sealingTW030WA12-freq-response
