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.

The latest addition to our range of tweeters is the SEAS Prestige DXT® tweeter, with controlled wide dispersion.
All SEAS tweeters are available with magnetic fluid in two different viscosities, which improves the heat transfer from the voice coil.
