As a large-format LCR loudspeaker, the SCL-1 is acoustically designed to complement the flagship SSW-1 dual 15” 5000 WRMS subwoofer and any of the JBL Synthesis Custom Loudspeakers (SCL series) as part of a complete JBL Synthesis solution. The SCL-1 features the patented JBL D2430K dual 3-inch (75mm) compression driver mated to a large, advanced geometry High Definition Imaging (HDI™) horn for extraordinarily detailed response and ultra-low distortion even at incredibly high listening levels.

Two newly designed 12” cast-frame Carbon Cellulose Composite Cone (C4) woofers work in conjunction with a patented Complementary Bass Alignment System (CBAS™) enclosure constructed from 1-inch (25mm) MDF with extensive internal bracing. The CBAS design combines the acoustic benefits of sealed enclosures (more output below tuning frequency) and vented enclosures (more output at the tuning frequency) with less impedance swings to play louder and work more efficiently with amplifiers. These driver elements combine with an innovative installer-configurable multi-capacitor crossover network that can be driven by a single amp, dual amps, or bypassed for use with active external crossovers.

We will not be responsible for any data loss.
