The Audison Voce AV 1.1 II tweeter showcases its engineering prowess by achieving Hi-Res Audio certification, a notable accomplishment for a tweeter with a Tetolon soft dome. Tetolon was specifically chosen for its superb sound timbre, allowing the tweeter to extend its frequency response up to 40kHz. This design provides unparalleled clarity and depth in high-frequency sound reproduction. Equipped with AIF (Any Install Faceplate) technology, the AV 1.1 II offers flexible installation options with various faceplates and accessories, ensuring perfect integration into any vehicle environment. This careful blend of advanced materials and versatile installation underscores the tweeter’s appeal to today’s car audio enthusiasts who demand the best performance. Give Sound Its True Voice Audison Voce II, the second generation of our iconic VOCE speakers, challenged us—to rethink how we design, test, and manufacture speakers. We’ve revamped materials, supply chains, assembly techniques, and packaging. Our goal was to “unlearn” to innovate and to “reinforce our expertise” where we knew we were on the right track. This dedication ensures that every aspect of VOCE II not only meets but exceeds the sophisticated demands of today’s car audio enthusiasts.
