SEAS Excel Dome Tweeters are available in 25 mm and 29 mm diaphragm sizes, with dome materials of textile, aluminium and high purity magnesium.

All Excel tweeters utilize extremely stiff die-cast front plate and rear chamber assemblies for maximum stability, excellent heat 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, result in smooth frequency response and low resonance frequency.

In the Millennium, Crescendo and Magnum 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.
