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, EVCoatTM finish, 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. The QRx153/75 has an excellent combination of performance and flexibility for demanding audiences. Technical Specifications: Freq. Range (-10 dB): 42Hz - 20kHz Freq.
