The Plastic Box that started it all. The JBL EON has a powerful legacy and the 515 builds upon that foundation. It delivers 450W continuous with a maximum SPL of 129dB from its 15-inch woofer and 1-inch tweeter. Despite its power, it remains lightweight and portable with built in handles and a pole mounting socket in the base. XLR and jack connectors with variable input sensitivity allows it to connect to a wide range of sources.
