With improved bass response and high-frequency reproduction, this speaker includes some of JBL’s top tech. Its Plus One® cone has more surface area than that found on competing models of the same size. Its My-Ti™ (Mylar®/titanium composite) tweeters offer increased power handling, reduced distortion and increased efficiency. Its Unipoint™ rotating tweeter pod allows the tweeter to rotate 350 degrees so it can be directed for optimal imaging. It can be driven by any head unit. The GT0 528 also includes a tweeter-level control, allowing easy adjustment of tweeter output even after installation.
