The JBL SCS12 is a coaxial-driver, 2-way, full range cinema surround loudspeaker ideal for multi-channel surround formats and is designed for overhead installation as well as for standard on-wall installations. The SCS 12 is comprised of a high-power coaxial 300 mm (12") low frequency driver and 25 mm (1") high frequency compression driver. The co-axial design utilizes a unique tapered pole-piece design and transitions to the cone of the low frequency driver as a large diameter pattern control horn for the high frequencies, both eliminating high-frequency beaming and extending pattern control to the lowest possible frequencies. The result is a coaxial speaker with wide, extremely consistent 100deg. coverage on a broadband basis.
Component features include a Kevlar reinforced low-frequency cone for reliability, well-damped surround edge for smooth frequency response, high-temperature 75 mm (3") voice coil and a reduced distortion design through saturated-gap geometry. The high-frequency compression driver features a unique patented design, high-temperature polymer diaphragm and fluid cooling for high output levels with low distortion. The enclosure is constructed of thick ABS plus fiberglass and is heavily braced to maximize low-frequency performance. A heavy-duty U-type mounting bracket is included.
