This 3-way speaker features JBL’s signature 12″ woofer, dedicated midrange driver, and pure paper-cone tweeter, all housed in a rugged cabinet with front-firing ports for easy room placement. Whether you’re into jazz, classic rock, or acoustic sessions, the 4312 gives you the clarity, punch, and liveliness that defines the JBL legacy.
