Electro Voice

The QRx-115/75 is a two-way, full-range loudspeaker system that incorporates a 15-inch woofer and a 3-inch voice coil compression driver on an asymmetrical 75-degree x 50-degree fully rotatable constant-directivity horn. In factorydelivered position the horn provides a 15-degree up/35-degree down vertical coverage pattern.

The five-sided cabinet design allows this main PA system cabinet to easily conform to duties as a floor monitor or to be tucked tightly against a ceiling for low-profile applications. The fully rotatable horn means regardless of cabinet position, pattern control is fully user-determined.
The QRx-115/75 is a good solution for small-to-medium size rooms as a main PA, providing moderate levels with good bass response in music or speech reproduction for DJs or live bands. The asymmetrical horn can allow a single box to more adequately direct the high frequencies as needed, as well as streamline multi-cabinet arrays extending horizontal coverage while minimizing overlapping and allowing tighter packs between the cabinets.
