Product Information

The most compact round in-ceiling model in the JBL Synthesis Custom Loudspeaker (SCL) series, the SCL-8 is designed for unparalleled performance in small to medium theater rooms for immersive applications as a height channel, or in high-performance two-channel applications and distributed whole-house audio. The SCL-8 features the patented JBL D2410H-2 1-inch (25mm) compression driver mated to an offset High Definition Imaging (HDI™) horn and an angled 5.25-inch advanced aluminum matrix cone cast-frame woofer with integral waveguide baffle allowing the loudspeaker to be “aimed”, focusing its output towards a specific listening area. The SCL-8 is acoustically designed to complement any of the JBL Synthesis Custom Loudspeakers (SCL series) as part of a complete JBL Synthesis solution.
