The SCL-6 is the largest in-wall model in the expanded in the JBL Synthesis Custom Loudspeaker (SCL) series. It is designed for deployment in high-performance immersive audio systems in medium to large size rooms. The SCL-6 features JBL’s patented 2410H-2 1-inch (25mm) compression driver mated to a High Definition Imaging (HDI™) horn. This patented horn design is integrated with four 5.25-inch (130mm) Advanced Aluminum Matrix cone cast-frame woofers into a precision molded baffle assembly. The configuration yields incredibly smooth and consistent performance for in-wall LCR or surround applications. Premium components are used throughout the crossover network including a boundary gain adjustment switch while high-quality gold-plated push type speaker terminals ensure a secure connection. Installation is simple and quick with the new Cat Claw mounting mechanism that allows the speaker to be securely clicked into place freeing up two hands for tightening it down flush and level to the wall. A zero bezel magnetically attached grille is included and can be painted to match any décor. The SCL-6 is acoustically designed to match any of the JBL Synthesis Custom Loudspeakers (SCL series) as part of a complete JBL Synthesis immersive audio solution.
