QSC E115 15" Two-Way Passive Loudspeaker
The E115 is QSC's largest single two-way box in the E Series line, built around a 15-inch die-cast-aluminum woofer with a 3.5-inch voice coil paired with a 2.8-inch compression driver on a 75-degree DMT waveguide. Two side-mounted handles and a dual-angle pole socket make it manageable as a single-operator main or a floor wedge.
It takes 500 W continuous power (2000 W peak) and reaches 130 dB peak SPL at 1 meter with QSC processing, with dual NL4 connectors plus a barrier strip for input. QSC's own E15-CVR padded cover and E15YM-BK yoke mount are built specifically for this cabinet.
