About Electro-Voice QRx 112/75

The Electro-Voice QRX 112/75 12" 2-Way Full-Range Black Loudspeaker (Single) incorporates a 12" woofer and a 3-inch voice coil compression driver on an asymmetrical 75-degree x 50-degree fully rotatable constant-directivity horn. In factory-delivered 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 that regardless of cabinet position, pattern control is fully user-determined.

The QRX-112/75 is a good solution for small-to-medium size rooms as a main PA, providing optimized midrange reproduction for speech intelligibility and vocal clarity at moderate levels. As a floor monitor, the tight and clear midrange coupled to a large format HF diaphragm helps cut through stage rumble while delivering smooth reproduction. The asymmetrical horn can allow a single box to more adequately direct the high frequencies as needed, as well as streamline multi cabinet arrays by extending horizontal coverage while minimizing overlapping and allowing tighter packs between the cabinets.
