Tweeter Material: Ceramic Coated Aluminum Dome Tweeter
• We take our 2 series aluminum dome tweeter material and add a sputtered ceramic coating to the dome. The sputtering process is a coating of ceramic at a molecular level. It is not "painted on" or dipped in ceramic. If it were, the coating would be too thick, too heavy and inconsistent.
• Our ceramic coating imparts a stiffness on the center of the dome to prevent high frequency distortion caused by dome deformation at high power levels in high frequencies.
• We make adjustments in the voice coil materials to offset the small additional mass that the ceramic coating adds. This allows for the efficiency of the tweeter to be maintained and the high frequencies to be extended.
