Integrating Subwoofers with Arrays
The RoomMatch™ subwoofer modules are designed with the same width as the full-range modules (with the optional RMSFLY kit
installed) to allow use with most RoomMatch rigging accessories. RoomMatch subwoofer modules may be combined with full-range
modules in the same array, or used exclusively in subwoofer-only bass arrays. The choice of "flying" or floor mounting subwoofers
involves complex analysis of the venue physical dimensions and mounting limitations, room acoustics, aesthetic requirements, and de-
sired uniformity of coverage in the listening areas. While the analysis of all of these factors is beyond the scope of this document, your
local Bose Field Engineer or Technical Support professional can provide assistance in this area. Once the decision to array subwoofers
is confirmed, the following are typical subwoofer array configurations using RoomMatch rigging accessories:
Small Array Frame with Subwoofer Modules
The Small Array Frame (RMAFSM) allows up to 4 RoomMatch RMS215 subwoofer modules (with RMSFLY kits installed) to be config-
ured as a vertical column array. The vertical array dimensions provide increased directional control of low-frequencies in the vertical
plane. Subwoofer arrays with vertical column configurations are recommended to be installed with 0 degree pitch, to ensure equal
distribution of load forces in the rigging hardware.
Large Array Frame with Subwoofer Modules
The Large Array Frame (RMAFLG) allows up to 8 RoomMatch RMS215 subwoofer modules (with RMSFLY kits installed) to be config-
ured as a vertical column array. The vertical array dimensions provide increased directional control of low-frequencies in the vertical
plane. Subwoofer arrays with vertical column configurations are recommended to be installed with 0 degree pitch, to ensure equal
distribution of load forces in the rigging hardware.
Large Array Frame plus Extender Bars with Subwoofer Modules
The Large Array Frame with Extender Bars (RMXSRT or RMXLNG) is typically used to integrate subwoofer modules behind other mod-
ules in the same array. The Extender Bars can accommodate up to 2 RMS215 subwoofer modules mounted in the rear position. This
allows the Large Array Frame with Extender Bars to be configured as a "2 x 2" subwoofer array, with or without additional full-range
modules to be integrated in the same array. The largest RoomMatch array configuration using standard rigging accessories uses this
configuration with the "2 x 2" subwoofer array, plus an additional 6 full-range modules. Note: This configuration requires use of the
RMPULL bracket attached to the bottom full-range module to provide a third structural attachment point for the array (in addition to the
attachment points of the left and right rails). For DSP settings and directivity information for subwoofer arrays, please refer to the docu-
ment, "RoomMatch Array Rigging Frames and Accessories Installation and Safety Guidelines."
Using Subwoofer Threaded Inserts for Custom Rigging
The RoomMatch RMS215 subwoofer module is equipped with M10-size threaded inserts to allow suspension using graded eyebolts or
custom-designed rigging solutions. Please refer to the "RoomMatch Subwoofer Module Installation and Safety Guidelines" document
for additional information.
RMPINS Quick-Connect Pins
An optional accessory kit (RMPINS) is available with quick-connect pins designed to replace the standard threaded fasteners used for
module-to-module connections in RoomMatch arrays. The quick connect pins do not change the WLL ratings of any recommended
array configuration and can be used with either the full-range or subwoofer modules. Each kit contains 4 quick-connect pins, which are
required for each module in the array.
RMSHAD Gain Shading Kit
An optional gain shading kit (RMSHAD) is available for RoomMatch™ modules to attenuate the lower-3 compression drivers relative to
the upper-3 drivers. This option may provide more uniform coverage in array configurations with large changes in directivity index from
module to module. The need for the Gain Shading Kit is best determined by using Bose Modeler sound system design software and re-
viewing the room coverage predictions. For installation instructions, please refer to the document, "RoomMatch RMSHAD Module Gain
Shading Kit Accessory Instruction Sheet."
