Using VA4 Technol-ogy developed for the new KF700 Series, the MQ range re-places the MH and BV ranges of Virtual Array systems. TheSeries comprises matched sets of mid/high and low frequencyenclosures that enjoy complementary dimensions andtrapeziod angles to facilitate the creation of optimized-cov-erage arrays.The MQ1366 uses a single, horn-loaded 10-in midrange conewith a specially designed geometry that produces a time-coherent wavefront through the upper portion of the midrangethat is critical to vocal articulation. A phase plug with radialslots then serves to reduce the mechanical reactance of thesubsystem without affecting the directivity of the source,allowing for flawless arraying of multiple MQ mid/high mod-ules.A high power 2-in exit/75mm voice coil high frequency com-pression driver is mounted on a constant directivity horn forconsistent, accurate dispersal of HF information. The MQ1366provides a nominal coverage pattern of 60° (h) x 60° (v).APPLICATIONThe MQ1366 mid/high module works with the MQ1312 triple12-in low frequency module to create arrays for use in awide variety of permanently installed applications.The most common array configuration is 2x MQ1366’s sepa-rated by a single MQ1312. In such an array, a certain amountof splay must be provided to achieve optimal coverage. Rig-ging systems currently available allow users up to 10° ofoverlap between the mid/high enclosures.All MQ Series enclosures feature a comprehensive system of3/8”-16 threaded mounting points for maximum flexibilitywhen suspending arrays overhead.Applications include:Large House of WorshipArenaStadiumTheaterPerforming Arts CenterDESCRIPTIVE DATAConfiguration Mid/HighPowering BiamplifiedMF Subsystem 1x 10-in Horn-Loaded Cone, RadialPhase PlugHF Subsystem 1x 2-in Exit/75mm Voice CoilCompression Driver on ConstantDirectivity HornCabinet Type (shape) TrapezoidEnclosure Materials Baltic Birch PlywoodFinish Black PolyurethaneConnectors 4-Terminal Barrier Strip &1x Neutrik NL4 SpeakonSuspension Hardware (16) 3/8"-16 Threaded MountingSuspension Points (4 each top,bottom and sides)Grill Powder Coated Perforated SteelDimensions inches millimetersHeight 40.00 1016Width (front) 32.00 813Width (rear) 8.12 206Depth 25.61 650Trapezoid Angle 50°Weights pounds kilogramsNet Weight 164.5 75.1Shipping Weight 182 82.8Companion SystemsSub Bass SB528, BH822eLF MQ1312
