Q-SYS SC-223X Passive 3-Way Cinema Loudspeaker System with MH-1060X and LF-2215

Developed specifically for the unique requirements of professional motion picture playback, the SC-223X extends QSC’s commitment to the cinema market. As a member of the DCS Digital Cinema Speaker Series, the SC-223X is a 3-way, bi-amplified or passive screen channel loudspeaker system comprised of two main units—the MH-1060X mid-high frequency and the LF-2215 low-frequency.

The MH-1060X mid-high system features a high output, horn loaded 10" (254 mm) midrange cone driver and 2.4" (60 mm) titanium diaphragm compression driver mounted to an adjustable pan and tilt bracket. The MH-1060X includes a switch selectable passive crossover for bi-amp or fully passive operation. The MH-1060X provides extended frequency coverage for the critical midrange band. A high power 10" cone driver allows operation as low as 300 Hz in bi-amp mode and the advanced phase plug coupling permits a crossover point of 2200 Hz to the high-frequency horn. This ensures that most of the dialog range is reproduced by a single element, for unmatched intelligibility.

The LF-2215 dual 15" (381 mm) low-frequency enclosure is designed specifically to address the extended low-frequency response required for cinema applications. The LF-2215 covers the frequency range from 35 Hz to 500 Hz. Close Coupled Woofers (CCW), with their tight spacing between woofers, improves coupling.

The SC-223X is designed for ease of installation. The MH-1060X components come pre-assembled to reduce field assembly time. Three bolts are all that are required to secure the MH-1060X to the top of the LF-2215 enclosure
