    Wavecor Speaker Driver - TW030WA10 - 8 Ohm 30 mm Textile Tweeter

    TW030WA10 is a tweeter designed for applications requiring the highest level of performance, with extended and linear high frequency response and best consistency. 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 TW030WA10 offers an unusually low resonance frequency.



    • 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.
