    Wavecor Speaker Driver - TW030WA02 - 30mm Ferro Fluid Neodymium Textile Dome Tweeter - 4 Ohm

    Description
    TW030WA02 is identical to TW030WA01 with the exception that TW030WA02 features ferro fluid in the air gap. TW030WA02 is a high performance 30mm soft dome tweeter that works equally well for most demanding high frequency audio applications. The low resonance frequency and high power handling makes TW030WA02 the ideal tweeter for 2-way speakers, where standard tweeters will not do. The usage of dual neodymium magnets as power house ensures an almost perfect magnetic screening for demanding A/V applications. The low distortion and the smooth and extended frequency response combine extreme details and dynamics into making TW030WA02 the pearl of any high-end 2-channel system. Small size and high efficiency make TW030WA02 well suited for high quality multimedia applications. There is a version of TW030WA02 without face plate available for manufacturers, for building the unit directly into the cabinet baffle. The part number of this version is TW030WA04 and the electrical / acoustical specifications are identical to that of TW030WA02. Please contact us for more information.
