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-rotable asymmetrical waveguides 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 (3"
voice-coil, 1.4" 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.
