Super-Dome, high-performance tweeter to match a high-performance-speaker-system.
Massive 1.6-lb. magnetic structure provides quick response to short-duration signals and contributes to high efficiency, 2 to 4 times that of conventional dome radiators.
Lightweight aluminum voice coil on large 1 ½” high-temperature polyimide form dissipates high input power.
High-density Acoustifoam lens for the wide dispersion associated with smaller, low-output dome radiators.
Foam damper smoothes response in the upper octave.
Two layers of phenolic-impregnated linen, bonded together with wave patterns intersecting at 45° produce a dome of high stiffness, dimensional stability, and strength.
Ferro fluid held magnetically in the voice-coil gap damps coil motion for smooth response in the lower octaves.

The Super-Dome tweeter it the new generation of Interface speakers represents an extraordinary development in speaker design. Electro-Voice engineers have developed the first high-performance tweeter capable of matching the high efficiency and extended bass response found in our optimally vented, computer designed Interface: A. Super-Dome has the sonic excellence normally associated with a dome tweeter and the efficiency heretofore found only in cone tweeters two to four times that found in a standard dome. Plus, its voice coil will withstand a full 25 watts power input long term. That's five times the power handling capacity of other standard dome or cone tweeters.
While the angle or dispersion narrows at high frequencies with conventional tweeters, the high-density Acousti-foam lens in Super-Dome helps keep dispersion constant in the upper octaves. Acoustically transparent at lower tweeter frequencies, the lens becomes opaque at higher frequencies, reducing the effective diameter of the radiating surface, thus increasing the angle of dispersion.
The result is the wide, uniform high-frequency dispersion necessary for precise localization of sound, both lateral and front-to-back.
Super-Dome is found in six of seven speakers in the new third-generation Interface line. No matter which model you decide to buy, you are assured of outstanding performance and model-to-model sonic integrity. Our goal remains the same as it was in 1973 when we introduced the first Interface speaker-to offer you a speaker that sounds like music.
