27. ity Arrays The proprietary technology of RoomMatch loudspeakers allows module configurations to form a new class of curvilinear array that Bose has termed progressive directivity array The key concept of the Progressive Directivity Array is the ability to vary both horizon tal AND vertical coverage for each module in the array For most venues narrow patterns are used at the top of the array to cover rear listening areas with coverage patterns getting progressively wider at the bottom of the array for the front listening areas This flexibility allows the array coverage to be tailored to specific room dimensions and level requirements Additionally this approach uses the Directivity Index DI of modules to help equalize levels from front to back of the listening area without using drastic attenuation of the lower modules Figure 5 RoomMatch Progressive Directivity Array grills removed E Array Parts List RMAFSM Small Array Frame RM7010 array module 70 H x 10 V z RM7010 array module 70 H x 10 V RM9020 array module 90 H x 20 V RM12040 array module 120 H x 40 V Array Configuration Types RoomMatch rigging accessories allow for several basic types of module configurations surface mount full range only array full range with subwoofer array full range with cardioid subwoofer array subwoofer only array Each configuration requires different rigging hard ware accessories General guidelines for the a
