The JBL brand has become synonymous with the cinema experience. The SCL-4 continues this legacy. The two-way SCL in-wall loudspeakers are the first flush-mount compression driver loudspeakers using JBL Professional technology. The 7" cast-frame aluminum-cone woofer is ideal for in-wall or ceiling mounts. Utilizing the D2-derived 1-inch / 25mm annular ring Teonex® diaphragm compression driver with advanced HDI geometry horn, the SCL-4 provides extraordinary performance in a very small package.
