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

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

Note 5

It is generally a rough simplification to assume that loudspeaker transducer voice coils exhibit the characteristics of an inductor. Instead it is a far more accurate approach to use the more advanced model often referred to as the “Wright empirical model”, also used in LEAP-4 as the TSL model (www.linearx.com), involving parameters Krm, Erm, Kxm, and Exm. This more accurate transducer model is described in a technical paper (PDF) here.
