Speaker provider QSC Audio introduces four-way speaker for dome cinema arena

Both the mid/high and LF enclosures are built with standard dimensions to help ease installation in vertical or horizontal arrays and are constructed of heavily braced, 15mm concert tour-grade plywood. In addition, 16 M10 attachment points-per-enclosure are provided for safe suspension.

The DCS SC-424-8F also features a coax HF/VHF diaphragm, which has less mass than traditional diaphragms, resulting in improved dynamic range, extended high frequency response and lower distortion.

The two main units comprise the MHV-1090F mid-high/very-high-frequency system and the LF-4215-8F low-frequency system aimed at applications where a point-sourced surround channel or screen channel must be suspended or flown rather than mounted on a platform or the floor.

QSC has also introduced the SB-15121 subwoofer to its digital cinema speaker range. It has been designed for use in cinemas and post-production applications.

The 1500W, 21in low-frequency transducer features a 6in diameter voice coil in a vented, neodymium magnet structure that is designed to dissipate extreme amounts of heat and allow for excursion that is double that of typical 18in transducers.
