TWEETER D2904/950000 The Classic tweeters are among the many highly praised designs in Classic series. They have enjoyed success over 3 decades. And still among the best tweeters available. The D2905/9000 tweeter kick-started a new era with a line of very high quality 1" tweeters, today known as -9300, -9500, -9700 and -9800. Despite their many years on the marked still used in many top High-End speakers around the world. KEY FEATURES: ? 1" Textile Dome Diaphragm ? Ferro Fluid ? Low Resonant Rear Chamber ?
