GZCT 500IV-B adds to the brand’s Competition Series line

DAVIE, FLA., March 28, 2019 (MEDIAWIRE) – SounDigital USA, exclusive U.S. distributor of Ground Zero audio products, announced that the Ground Zero GZCT 500IV-B tweeter is now available to authorized retailers in the U.S. and Canada. The new speaker, introduced at the 2019 KnowledgeFest trade show and education conference in Indianapolis earlier this month, is a high-performance compression tweeter from the brand’s Competition Series, designed specifically for motorcycles. Its introduction gives bike audio retailers a versatile, high-frequency driver in a design ideal for custom installations.

The GZCT 500IV-B features a compact diameter for minimal surface area installations. Its screw-on bezel provides an attractive surface-mount solution for drop-in replacement or custom installs, and rust-resistant rear screw terminals connect it to the radio or amplifier. It’s capable of 30 watts RMS and 100 watts maximum power handling with a rated frequency response of 4kHz – 25kHz.

The element-resistant black chassis houses an aluminum dome tweeter and cast baffle, driven by a one-inch, copper-clad aluminum flat-wire voice coil capable of four-ohm impedance loads. A plastic phase plug enables installers to mount the tweeter to fire toward the rider from the front or rear.

“Our response from retailers at KnowledgeFest was phenomenal,” said Diogo Ianaconi, CEO of SounDigital USA. “Traditional bike audio retailers who know the quality of Ground Zero tweeters liked its crisp, clear performance. And several car audio retailers that don’t typically do bike installs are now seeing a new profit center. We think the new tweeter will be a popular addition to Ground Zero’s Competition line.”

The GZCT 500IV-B has an MSRP of $99 each and is sold as a single speaker.
