QSC 115 speaker
The QSC115 is a trapezoidal, two-way loudspeaker using a 15-inch, 500W, die cast aluminum frame woofer with a 3.5-inch voice coil. It is intended for use when high-power and authoritative low-end are needed from a full-range loudspeaker. A 2.8” compression driver attached to the 75° DMTTM waveguide assures that even distant listeners will be well covered.
