Get to know this product.

The JBL brand has become synonymous with the cinema experience. The SCL-3 was designed to continue this legacy. The two-way SCL in-wall loudspeakers are the first flush-mount compression driver loudspeakers using JBL Professional technology. The dual 5-¼" cast frame aluminum woofers are ideal for in-wall or ceiling mounting. Utilizing the D2-derived 1-inch / 25mm annular ring compression driver with Teonex® diaphragm and an advanced HDI geometry horn, the SCL-3 provides unparalleled performance compared to any in-wall loudspeaker in the market today.
