WHY IT EXISTS
A domestic loudspeaker built with cinema-scale instincts.
The SCL-1 is the flagship of JBL Synthesis Custom Loudspeakers and is optimized for LCR use behind projection screens or in custom cabinetry.
Its large horn and dual 12-inch bass architecture are about maintaining dynamics and low distortion at listening distances where smaller architectural speakers would be working much harder.
SYSTEM ROLE
Where it fits in a cinema.
Projection screen
Particularly natural behind an acoustically transparent screen.
JBL ecosystem
Voiced to integrate with the wider SCL loudspeaker family.
ROOM DESIGN
Choose the room conditions before choosing the quantity.
Baffle wallAllow sufficient depth and service access for a large enclosure.
CoverageUse the horn geometry to map the seating area before construction.
AmplificationThe crossover can support different amplification approaches; decide the architecture early.
