Electro-Voice Introduces QRx212H/75 LoudspeakerQRx212H/75 Two-Way, High-Power Full-Range System for Active or Passive Operation and Horizontal Mounting  January 22, 2003
EV (Electro-Voice) introduced their dual 12-inch two-way full-range QRx212H/75 loudspeaker at Winter NAMM, the newest addition to its line of QRx loudspeakers. QRx loudspeaker systems provide high-quality audio solutions for both portable and demanding installations.
QRx loudspeakers function as a main PA and as stage monitors. For low-profile/limited clearance installations, QRx requires less space than standard trap boxes when used in horizontal box hangs, and arraying is simplified.
The QRx-212H/75 is a full-range, two-way loudspeaker system that incorporates two 12-inch woofers and a 3-inch voice coil compression driver on an asymmetrical 75-degree x 50-degree rotatable constant directivity horn. In factory delivered position, the horn provides a 15-degree up/35-degree down vertical coverage pattern. The rotatable horn allows 180-degree rotated mounting possible, while keeping nominal coverage. The fully rotatable horn means pattern control is user-determined, regardless of cabinet position. The QRx-212H/75 also offers excellent horizontal mounting and boundary surface coupling.
The QRx-212H/75 features 43 -- 18,000 Hz (-10 dB) frequency response (measured on axis) and 650 watts continuous power handling (passive). The QRx-212/75 features two DL12Sx 12-inch woofers, the new large-format DH-7 driver with a 3-inch voice coil on fully rotatable asymmetrical CD horn, Ring Mode Decoupling (RMD), two Neutrik Speakon connectors, and 13-ply Birch plywood. The QRx-212H/75 also features an integrated crossover with an acoustic crossover frequency of 2,000 Hz. To ensure proper performance in a variety of conditions and by operators of varied experience, the QRx-212H/75 also features dynamic protection circuit for independent protection of both ways against thermal overload.
