Welcome to our SEAS Prestige tweeter product line.
We have dome tweeters with 19 and 25mm voice coil diameters and different surround diameters. The rigid chassis are made from glass filled engineering plastic materials by injection moulding. Further, the chassis may be custom designed to specified shapes, surface finishes, fixing holes, logos etc, within wide limits.
We offer dome diaphragms made from soft materials such as impregnated fabric, aluminium and titanium. The latter is equipped with a soft surround which suspends the dome diaphragm in a compliant, but precise and dependable manner. All dome diaphragms and surrounds are made in-house at SEAS, except for anodized aluminium and titanium.
The relatively fragile aluminium diaphragms may be protected by wire mesh or perforated metal grilles, or by plastic diffusers. The diffusers also linearize the frequency response to an amazing degree.
All SEAS tweeters are available with magnetic fluid in two different viscosities, which improves the heat transfer from the voice coil.
