SEAS Excel Dome Tweeters are available in 25 mm, 29 mm and 35mm diaphragm sizes, with dome materials of fabric, diamond, Metamodal TPCD and glass.
All Excel tweeters utilize extremely stiff front plates for maximum stability transfer and minimum cabinet induced vibration.
Excel tweeters feature advanced magnet systems that combine high magnetic flux with optimum venting of the critical areas behind the dome. They utilize magnets of high strength ferrite or neodymium, depending on the model. Large vent holes in the pole piece combined with critically placed damping materials and optimally shaped rear chambers result in smooth frequency response and low resonance frequency.
In the White Diamond, Millennium, Crescendo and Metamodal TPCD tweeters our patented Hexadym magnet system further reduces reflections and back pressure by allowing full venting of the voice coil gap and the space behind the dome surround.
