The QRx153 is designed to be bi-amplified at 500 Hz utilizing
a DX38 digital controller, or a P1202 power amplifier with
M153 control module. All QRx models use 13 ply plywood,
Futura coating, and steel grilles for wear and weather
resistance. The QRx153 is trapezoidal with 15o side angles.
“L” track rigging is installed on the enclosure top and bottom.
Small arrays can be flown for live work, or the system can be
suspended horizontally or vertically for fixed installations.

Thanks to its combination of the DL15ST woofer and large
enclosure volume; the horn-loaded 8-inch midrange driver
and powerful 3-inch compression driver, the EV QRx153/75
has extended response for high-level, high fidelity applications
without the need of a subwoofer. The horn-loaded midrange
driver provides excellent pattern control in this critical
response area. Both MF and HF horns are aimed downward
10o to provide optimal aiming when the speaker is elevated
above the audience. This also helps control sound to provide
greater intelligibility.
