PRO.BOSE.COM Overview Overview Introduction Using this design guide, you will be able to create designs for applications that utilize in-ceiling loudspeakers. We offer additional design guides for surface-mount and pendant-mount loudspeakers, as well as dedicated design guides for EdgeMax and FreeSpace 3 sub-satellite systems. To learn more about our loudspeakers and technology capabilities, as well as access additional trainings and tutorials, visit proedu.Bose.com/learn.
Design Worksheet PRO.BOSE.COM Design Worksheet Use the following worksheet to create a design using Bose Professional loudspeakers. Choosing a Model Step 1: Loudness Maximum SPL Capability Confirm that your chosen loudspeaker model will meet your loudness requirement. Find your ceiling height and follow the column down until you reach your desired maximum continuous output level. Models with a higher sensitivity and higher tap settings will be able to play at higher levels.

Design Worksheet PRO.BOSE.COM Loudspeaker Spacing Loudspeaker LSD = Spacing Distance M = Multiplier LSD is also the coverage area for one loudspeaker Loudspeaker Spacing LSD = (H – L) × M For small rooms such as bathrooms, you may only need one or two loudspeakers to cover the room; look at LSD 2"–4" Small Woofer Coverage M (multiplier) Models Edge-to-edge 3.46 Minimum Overlap 2.45 Center-to-center 1.73 FS2C DM2C-LP DM3C FS4CE 5"–8" Large Woofer Coverage M (multiplier) Edge-to-edge 2.
Design Worksheet PRO.BOSE.COM C. The remaining loudspeakers are arranged on a square grid pattern using the LSD. If a loudspeaker would be placed on or beyond the perimeter of the room, delete that row/column of loudspeakers. Loudspeaker Spacing Loudspeaker Spacing D. After the last loudspeaker is placed, center the loudspeakers in that row to create new offset distances out from each wall, which may be unique from ½ LSD. E.
Design Worksheet PRO.BOSE.COM Step 5: Calculate Required Amplifier Size All FreeSpace FS, DesignMax, and EdgeMax loudspeakers are compatible with 70-volt, 100-volt, and lowimpedance amplifiers. Use the Tap Charts to determine which loudspeaker tap is required for this design A. Locate the loudspeaker tap chart and find the column for mounting height for this design. B. Follow the column to the desired maximum SPL. C. Follow the row across the chart to determine the required loudspeaker tap. D.
Tap Charts PRO.BOSE.COM Tap Charts Individual Loudspeaker Continuous Output Level Note: The following tap charts assume standing ear height at 1.5 meters (5 feet) in minimum overlap spacing. Room reverberation could add as much as 4 dB system gain, which is not factored into the measurements. Designing without room gain will ensure you don’t under-plan your design, and amp attenuation is possible at the job site if you exceed the average room SPL target during measurement.
