Appropriate Venues for RoomMatch Arrays
RoomMatch array module loudspeakers are designed to provide concert-quality sound for indoor, fixed-installation venues, such as per-
forming arts centers, auditoriums, houses of worship, gymnasiums, and indoor sports areas. The flexible configuration of RoomMatch™
modules allows high-quality sound in these venue types, ranging from several hundred seats to more than 20,000 seats. However,
RoomMatch is not recommended for outdoor installations or portable, touring-sound applications.
Introduction to Progressive Directivity 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.

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 accessories required for each of these categories is presented in the following section.
Surface-Mount. Mounting a single full-range module to a wall or ceiling surface requires use of the RMBRKT accessory. Suspension of
a full-range module using wire rope (or other materials) attached directly to the module side plates is not recommended.
Full-Range Only. For arrays requiring only full-range modules, the RMPULL, RMAFSM, or RMAFLG accessories may be used, depend-
ing on number of array modules. The RMPULL bracket can accommodate 1 or 2 full-range modules (cannot be used with subwoofer
modules). The RMAFSM and RMAFLG frames accommodate up to 4 and 8 modules respectively.
Full-Range with Subwoofer. For arrays requiring full-range and subwoofer modules, the RMAFSM frame may be used for arrays of up
to 4 modules, while the RMAFLG frame can be used with arrays of up to 8 modules. The optional RMSFLY side-plate kit is required to
mount the RMS215 subwoofer module in arrays. (The RMS215 module is shipped without side plates). The RMS215 subwoofer module
should always be placed in the top positions, above any full-range modules.
Full-Range with Rear-Mounted Subwoofers. For arrays requiring full-range modules with subwoofer modules mounted behind the pri-
mary array (including cardioid subwoofer arrays), the RMXLNG or RMXSRT Extender Bars must be used with the RMAFLG Large Array
Frame. The largest array possible with these standard rigging accessories is 8 modules in the front position suspended from the Large
Array Frame and 2 additional subwoofer modules suspended from the Extension Bars in the rear position.
