The JBL SCL-3 is engineered to bring the unmatched performance of JBL Professional cinema technology into your home theater with a flush-mount design that blends seamlessly into any space. As part of the JBL Synthesis Custom Loudspeaker (SCL) series, the SCL-3 is a two-way in-wall loudspeaker that combines JBL’s legendary compression driver technology with advanced acoustic engineering.

At its core, the SCL-3 features dual 5-¼" (130mm) cast-frame aluminum matrix cone woofers, paired with a D2-derived 1" (25mm) annular ring compression driver utilizing a Teonex® diaphragm. This driver is integrated with JBL’s patented High-Definition Imaging (HDI™) horn geometry, delivering remarkable clarity, precision imaging, and wide dynamic range across the listening area. The result is reference-quality sound that rivals even the most advanced floorstanding loudspeakers.

The versatile design of the SCL-3 allows for flexible installation in any orientation, making it ideal as a left, center, or right channel, as well as a side or rear surround, or ceiling-mounted for overhead Dolby Atmos and immersive audio systems. Its patent-pending extended range L-bracket mounting system, zero-bezel magnetic grille, and low-resonance MDF enclosure ensure both ease of installation and superior acoustic control. With dual binding post inputs for bi-wiring or bi-amping, the SCL-3 can be integrated into high-performance systems with maximum flexibility.

Whether used in a dedicated theater or a multipurpose media room, the JBL SCL-3 elevates the in-wall speaker category with uncompromising performance, cinematic dynamics, and refined detail—bringing the true JBL cinema experience home.
