TW030WA09/10 30 mm textile tweeter, 4/8 ohm

TW030WA09 and TW030WA10 are tweeters designed for applications requiring the highest level of performance, with extended and linear high frequency response and best consistency. Innovation Tweeters used to feature a separate rear chamber in order to obtain low resonance frequency. Not any longer. By designing the internal parts to accommodate new larger internal volumes, the TW030WA09/10 offer an unusually low resonance frequency.

Key features:
  • 30 mm design with controlled off-axis and power response, high power handling, and low resonance frequency
  • 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 sealing
