Q-SYS SC-444 Tri or Quad-Amp 4-Way 4x15-inch Cinema Loudspeaker System with 2x LF-4215 and MHV-1090
The Q-SYS SC-444 cinema loudspeaker system is purpose-built for professional motion picture playback, providing exceptional clarity and intelligibility. Part of the DCS Digital Cinema Speaker Series, the SC-444 is a 4-way system that can be operated in tri or quad amplification. It comprises dual LF-4215 low-frequency units and the MHV-1090 mid-high-very high system, which uses a unique HF/VHF coaxial driver for high output and low distortion. The SC-444 is THX-approved and ideal for high-performance cinema applications.
Features:
- 4-way, selectable tri or quad-amplified screen channel system
