    Wavecor Speaker Driver - TW030WA06 - 4 Ohm 30mm Chambered Textile Tweeter with Ferro Fluid

    Description
    Real high-end tweeter design with extremely low resonance frequency and distortion. Thanks to the extensive internal venting between three internal cavities no air inside is trapped. This feature extends the usable frequency range downwards to an extend very rarely found on tweeters. Adding the high power handling this tweeter is the natural candidate for high-end 2-way speaker systems.

     

    Features

    • Precision-coated textile diaphragm for improved consistency and high-frequency extension
    • Extreme internal venting through pole, voice coil former, and top plate to 3 internal chambers
    • Copper-clad aluminium voice coil wire offering lower moving mass for improved efficiency and transient response
    • Reflection-free rear chamber design with solid reinforcement ribs
    • Large ferrite magnet for improved efficiency and transient response
    • With or without high-stability light ferro fluid
    • 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
    • Delivered with EVA gasket attached for hassle-free mounting and secure cabinet sealing

    Note 1. 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. Specifications are before burn-in
