Design Recommendations

When creating a design that uses the FreeSpace

DS 100F loudspeaker, you should consider

the following:

• Recommended mounting height for the FreeSpace DS 100F loudspeaker is between 12 and 32ft

(3.6 and 10m).

• Maximum SPL for a typical application is between 89 and 103 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 loudspeaker

spacing distance for your application.

*12.5-watt tap available only in 70V mode.

For more detailed information, refer to the FreeSpace DS 100F loudspeaker Design Guide.

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 100F loudspeaker.

Calculate the loudspeaker spacing distance by

multiplying the loudspeaker throw distance by

the desired coverage multiplier.

Calculate the loudspeaker

throw distance.
