About the JBL Synthesis SCL-2

The Synthesis SCL-2 in-wall speaker offers the highest level of acoustic performance available from a flush-mount loudspeaker. The integrated MDF enclosure is designed for installation in standard 2x6 wood frame construction, and Internal connections allow for bi-wiring or bi-amplification in advanced installations. The SCL-2 delivers unparalleled performance in a wide variety of applications and is ideal for use in medium, large, and extra-large rooms. The SCL-2 comes as standard with a white paintable grille.

Advanced Construction

The SCL-2 is designed with a 2.5-way, triple 8-inch (200mm) driver configuration for low-frequency extension with high output capability and powerful dynamics. A D2415K dual voice coil, dual 1.5-inch (38mm) annular ring diaphragm Teonex® compression driver with advanced HDI geometry horn works in conjunction with three powerful cast-frame, 8-inch (200mm) Advanced Aluminum Matrix cone woofers with low distortion motor structures.

Ultimate Performance

The SCL-2 has a 5.5-inch (140mm)-deep enclosure which fits standard wall construction applications and features a Sonoglass™ precision molded baffle assembly with integrated HDI waveguide/horn, and a zero-bezel, magnetically-attached grille. The loudspeaker’s enclosure can be oriented with the horn closer to the top or bottom, or on its side for center channel or reduced height applications. SCL-2 systems can be mixed and matched with other SCL speakers or any JBL Synthesis loudspeakers.

Designed to be discrete

Designed to provide ultimate performance and the highest levels of dynamics from any in-wall loudspeaker, the SCL-2 can discretely integrate into any environment and décor. They can also be installed in a traditional application behind acoustic fabric or woven/perforated video screens without installing the grilles. They feature a discrete matte black baffle, HDI waveguide, and transducers, with a paintable white grille. The SCL-2 is the perfect solution for in-wall LCR or surround channel applications as part of JBL Synthesis home theater.
