  • Technology

    Aluminum Dome Tweeter

    Lightweight Aluminum Dome tweeters deliver sparkling high-frequency detail that extends well beyond the frequency response of typical human hearing.

    Detailed Information:
    Compared to similar textile designs, aluminum tweeter diaphragms offer superior stiffness and high-frequency extension, with only a minor penalty in efficiency. JL Audio’s aluminum dome tweeters employ a rubber surround and ferrous fluid in the motor gap to damp the aluminum diaphragm. This additional damping reduces ringing and improves the tweeter’s smoothness of reproduction while still delivering the high-frequency energy and extension that metal domes are known for
