PRODUCT DESCRIPTION Addressing the growing demand for a compact and portable professional sound system, FBT developed the QUBE QSA 112 constant curvature line array. This system is mostly dedicated to fixed installation and to sound rental companies, which are looking for equipment with the best ratio performance/portability. The FBT QUBE QSA 112 delivers extraordinary power handling, clarity, flexibility and, of course, stunning sound in an attractive, easy to handle affordable package. Two way, true line array full-range / biamp system, in bass reflex, 1 x 12" (3" voice coil) neodymium woofer garanting high excursion and power handling. 3 x 1" (1.7" voice coil) neodymium compression drivers coupled to a waveguide with 100°H x 15°V dispersion. The FBT QUBE QSA 112 easy handle (bi-amp mode) 600W on the LF and 240W on the HF section with a peak SPL 130dB (LF) / 138dB (HF). High quality passive crossover network offering maximum reliability, with built-in soft thermal protection for the HF components with autoreset. Bi-amp or full-range passive mode selection from the rear panel. High frequency shelving EQ switch (-3dB, 0dB, +3dB) allows effective amplitude shading technique, to evenly uniform the SPL of the mid-high frequencies in the listening area.The speaker is made with birch plywood finished with scratch resistant paint. Integrated handles and mechanical hardware for suspension with 10:1 safety factor are included.
