The QW monitors offer a clean, clear response and reliability in a premium high quality, high power stage monitor system. These are full-range or bi-ampable two-way full-range floor monitor loudspeaker systems with a Pro Rider 15 inch woofer with Kevlar impregnated cone and 4 inch voice coil, a 44XT 4 inch titanium diaphragm compression driver with ferrofluid, coupled to a CH 942qt conical horn with Sound Guard 44 high frequency protection. The shape of the QW monitor reduces the buildup of standing waves inside the enclosure while the high frequency driver utilizes the patented Radialinear Planar Phase Correction System to provide smoother and extended high frequency response. The CH-6 conical constant directivity horn provides an even 60 degree coverage in all directions. Connection is made through 2 parallel full-range or 2 parallel bi-amp Neutrik Speakon connectors.
