Excel Woofers

The SEAS Excel woofer Line offers 2 proprietary cone materials, available in drivers sized from 12 cm to 26 cm. SEAS is the only loudspeaker company in the world to offer high purity, die-cast and machined magnesium cones. These cones feature extremely high stiffness along with good internal damping. SEAS Excel Magnesium cone drivers are world renowned for their high definition, low distortion and sound reproduction.

For those listeneres preferring soft cone drivers, the SEAS Excel Line offers our exclusive Nextel series. Excel Nextel drives feature a "sandwich" construction of paper, coated with Nextel paint on the front surface and damping compound on the rear. The resulting cone is both lightweight and well damped; offering an extreremly linear frequency response.

All SEAS Excel woofers feature advanced motor structures utilizing copper shorting rings above and below the gap, as well as solid metal phase plugs for superior acoustical performance and enhanced cooling.

Excel Tweeters

SEAS Excel Dome Tweeters are available in 25 mm, 29 mm and 35mm diaphragm sizes, with dome materials of textile, beryllium and diamond.

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 and Crescendo 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.

Excel Coaxial Drivers

SEAS designed and manufactured its first coaxial drivers more than 20 years ago.
Early on, R&D engineer Bjørn Børja recognized the unique possibilities created by the new neodymium magnet technologies; allowing us to design a high performance tweeter in a very compact package. SEAS has continuously refined coaxial driver technology over the years, and today remains the only loudspeaker driver manufacturer to make this unique technology available to the OEM and hobbyist markets.

Never standing still, the R&D lab recently decided to see what could be accomplished by applying our state of the art Excel technology to a coaxial drive unit. The answer can be found in our new Excel C16N001/F, and the results are amazing.
