JBL Synthesis SCL-8
The SCL-8 is the most compact round in-ceiling model in the JBL Synthesis Custom Loudspeaker (SCL) series. It is designed for use as a height channel or in-ceiling LCR or surround channel loudspeaker. The SCL-8 features JBL’s patented 2410H-2 1-inch (25mm) compression driver mated to an offset High Definition Imaging (HDI™) horn. This patented horn design is integrated with an angled 5.25-inch (130mm) Advanced Aluminum Matrix cone cast-frame woofer operating behind an acoustic aperture waveguide. The innovative configuration yields incredibly smooth and consistent performance for off-axis placement up to 60 degrees from the listening position. The SCL-8 is acoustically designed to match any of the JBL Synthesis Custom Loudspeakers (SCL series) as part of a complete JBL Synthesis immersive audio solution. It is ideal for use in small to medium rooms.
