Product description The Electro-Voice QRx-212H/75 is a 2-way P.A. loudspeaker with a 600-watt continuous power handling capacity. The unit features dual 12" woofers and a 3"" titanium compression driver loaded into a full-rotation asymmetrical CD horn. The unit functions as a main or stage P.A. monitor, and for low-profile/low clearance installs requires less space when horizontally positioned than most standard trap boxes, simplifying array setup. The QRx-212H/75 may be operated in passive or bi-amplified mode, with independent performance, and offers the appropriate switches at the input section set. The rugged 13-ply Futura-finished cabinet is equipped with rigging suspension hardware, and a set of 4 Ancra single-stud fittings. The speaker also features a dynamic protection circuit for independent 2-way protection against thermal overload.
