Q-SYS SC-434 Tri or Quad-Amp 4-Way 3x15-inch Cinema Loudspeaker System with LF-4315 and MHV-1090

Q-SYS SC-434 Tri or Quad-Amp 4-Way 3x15-inch Cinema Loudspeaker System with LF-4315 and MHV-1090

SC-434 is four-way, selectable tri or quad-amplified screen channel loudspeaker system comprised of two main units the MHV-1090 high-frequency system and the LF-4315 low-frequency system. The MHV-1090 mid-high-very high system features a high output, horn loaded 10-inch midrange cone driver and a coaxial neodymium high-frequency/very high-frequency compression driver. The LF-4315 triple 15-inch (381mm) low-frequency enclosure is designed specifically to address the extended low-frequency response required for cinema applications.

Features:

• Four-way selectable, tri or quad- amplified screen channel system
• Unique HF/VHF diaphragm has less mass than traditional diaphragms resulting in exceptional dynamic range, extended high frequency response and lower distortion
• LF-4315 is constructed of MDF and is heavily braced
• Low-distortion waveguides provide highly articulate dialogue
• Shallow depth (20-inch) facilitates installation
