Audax are well known for their fine tweeters, among these the 25mm soft dome TW025A0 used in numerous high-fidelity loudspeakers world-wide, including such brands as Mission, Von Schweikert, Wilson, etc. The TW025A0 is a high-quality 8 ohm 25mm voice coil tweeter, a direct replacement for older Audax 100 mm circular flange tweeters but with improved performance. (Also see Audax TW025A1-12X9 s a replacement for rectangular flanged Audax tweeters.) The TW025A0 features a solid aluminum faceplate, replaceable voice-coil assembly and very linear response. This is the newest version of the older Audax or Poyldax tweeter HD100D25 in 8 ohm.

The catenary (curved) shape of this textile dome provides stiffness at the tip, so the moving mass behaves more like a perfect piston. This prevents out of phase break-up and the resulting sound is smooth, clean and effortless. Low resonant frequency. Flange 100mm (3.94") Cut out 73.5mm (2.89") Depth 23.5mm (0.94").
