90º x 90º TRACTRIX HORN Our exclusive Tractrix® horn technology delivers the power, detail and emotion of the live music experience with the cleanest, most natural sound possible. LINEAR TRAVEL SUSPENSION (LTS) ALUMINUM TWEETER WITH KAPTON SUSPENSION The exclusive Linear Travel Suspension (LTS) minimizes distortion for enhanced, detailed performances.

When paired with the Tractrix Horn-loaded LTS tweeter, it provides speaker efficiency highest in its class.
