Design Recommendations

When creating a design with FreeSpace DS 40SE
loudspeakers, consider the following:
• FreeSpace DS 40SE loudspeakers are ideally
suited to background and foreground music
and paging applications. If your customer's
requirement is for a foreground music system,
consider the FreeSpace DS 100SE loudspeaker.
For background music systems, consider the
FreeSpace DS 16SE loudspeaker.
• Recommended mounting height for the
FreeSpace DS 40SE loudspeaker is between
8 and 26ft (2.4 and 8m).
• Maximum SPL for a typical application is
between 90 and 97 dB-SPL.
• Always add 25% headroom to your
amplifier to accommodate various types
of program material.
Total system sound pressure level varies by mounting height, loudspeaker tap and room acoustics.
For typical applications, use the chart below to determine the total sound pressure level attainable
for a system using DS 40SE loudspeakers.
