Design Recommendations

When creating a design that uses FreeSpace
• The FreeSpace DS 16F loudspeaker is ideally suited to background music and paging applications. If
your customer's requirement is for a foreground music system, consider the FreeSpace DS 100F loud-
speaker. For background and foreground music systems, consider the FreeSpace DS 40F loudspeaker.
• Recommended mounting height for the FreeSpace DS 16F loudspeaker is between 8 and 20ft (2.4 and 6.1m).
• Maximum SPL for a typical application is between 87 and 99 dB-SPL.
• Always add 25% headroom to your amplifier to accommodate various types of program material.
Coverage requirements vary for each application, and the loudspeaker spacing will vary based on
mounting height and listener height. Use the following two steps to calculate the required loud-
speaker spacing distance for your application.
1 Calculate the loudspeaker
throw distance.
Total system sound pressure level varies based on the mounting height, loudspeaker tap and room
acoustics. For typical applications, use the chart below to determine the total sound pressure level
that will be achieved using the DS 16F loudspeakers.

2 Calculate the loudspeaker spacing distance by
multiplying the loudspeaker throw distance by
the desired coverage multiplier.
