TW030WA01 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 TW030WA01 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 TW030WA01 the pearl of any high-end 2-channel system. Small size and high efficiency make TW030WA01 well suited for high quality multimedia applications. TW030WA01 is available with ferro fluid as part number TW030WA02.
