Design Recommendations

When creating a design that uses the FreeSpace
DS 100SE loudspeakers, you should consider
the following:
• Recommended mounting height is between
8 and 26ft (2.4 and 8m).
• Provide at least 20ft (6.1m) of space between
adjacent loudspeakers for typical applications.
• In outdoor applications, do not space the
loudspeakers by more than 50ft (15.2m).
• Generally, the FreeSpace DS 100SE loudspeakers
should be pitched downward between 5 and
15 degrees.
• Maximum SPL for a typical application is
between 91 and 98 dB-SPL.
• Always add 25% headroom to your amplifier to
accommodate various types of program material.
Use the following recommended loudspeaker
spacing guidelines for typical mounting heights
between 12 and 22ft (3.6 and 6.7m), as coverage
requirements and loudspeaker spacing will vary.

Connectors:
The included mounting bracket features a
