QRx portable passive loudspeakers

The QRx series has become the standard for regional sound companies, rental professionals, and contractors who want compact high-performance loudspeakers with concert-grade EV components. Covered with rugged EVCOAT, QRx looks great stacked, on poles, as monitors, or flown with simple, integrated, L-track rigging points. Unique, fully-rotatable asymmetrical horns have a 15-degree downward bias to ensure high-frequency coverage without the need to tilt the enclosure toward the audience. Our powerhouse DH7 large-format driver (three-inch voice-coil, 1.4-inch exit) provides the high-frequency engine, while a selection of DL and EVX woofers anchor the low and sub frequencies. The combination of high-level components, unique design, and versatility make QRx series one of the best values in the industry.
