Product Overview
The Bose® FreeSpace® DS 100SE loudspeaker is a
high-performance, surface-mount loudspeaker
designed for foreground music and speech
reproduction in a wide range of commercial
applications, including retail, restaurant and
hospitality establishments.
This 100-watt loudspeaker can be installed up to
30ft (10m) high, both indoors and outdoors. The
contemporary styling easily blends with a wide
variety of décors. Horizontal or vertical mounting options offer installation flexibility. The DS
100SE loudspeaker meets numerous standards
for combination music and evacuation systems
around the world when used with the optional
junction boxes.
Product Information
The FreeSpace DS 100SE surface-mount loudspeaker
is engineered for installation on walls and other
solid surfaces. Simple 1-2-3 installation: (1) Wire
and attach the wall bracket (2) Secure the loudspeaker to the wall bracket with one screw (3)
Snap the wire connector into the wall bracket.
The included bracket allows for horizontal or
vertical mounting positions, each with either
pitch or yaw adjustment.
The DS 100SE loudspeaker can be used as an
8-ohm, 100-watt loudspeaker or as a 70/100V
loudspeaker. An easy-to-access thumbwheel
allows taps to be set quickly and simply without
the use of tools.
Two Twiddler® drivers in a proprietary Articulated
Array® loudspeaker design provide a 180°H x 75°V
dispersion pattern out of the box when the loudspeaker is mounted horizontally. The array can be
rotated easily to maintain this wide horizontal
dispersion pattern when the loudspeaker is
installed in the vertical orientation.
Performance of the FreeSpace DS 100SE loudspeaker can be maximized through the use of
the recommended Bose loudspeaker equalization
resident in select Bose electronics, or by using
other equipment with parametric equalization.
The loudspeaker can be used out of the box with
a 55-Hz high-pass filter when recommended
loudspeaker equalization is not used. The DS 100SE
loudspeaker is acoustically compatible with the
DS 100F flush-mount loudspeaker and can be
integrated on the same loudspeaker line.

Additional Product Information
This product is equipped with a protection
circuit that will reduce the high frequencies
to an audibly lower level when the loudspeaker
is overdriven. In the event the protection circuit
is activated, reduce the input level.

Design Recommendations
When creating a design that uses the FreeSpace®
DS 100SE loudspeaker, 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 loudspeaker
should be pitched downward between 0 and
15 degrees.
• Maximum SPL for a typical application is
between 89 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.
Coverage
Loudspeaker Spacing Distance
Premium
40ft | 12m
Standard
50ft | 15m
Minimum

Total system SPL varies based on the mounting height,
tap setting and room acoustics. For typical applications,
use the chart below to determine the total SPL.

How our Loudspeakers are
Measured
1. Power handling
Full-bandwidth pink noise, meeting the IEC
Standard #268-5, is applied to the loudspeaker
and amplified to a level at the loudspeaker
terminals corresponding to the power handling
of the loudspeaker. The loudspeaker must show
no visible damage or measurable loss of performance after 100 hours of continuous testing.
2. Sensitivity
Full-bandwidth pink noise is applied to the loudspeaker with its active equalization curve and
amplified to a level at the loudspeaker terminals
corresponding to 1 watt, as referenced to the
nominal impedance. The average sound pressure
level (dB-SPL) is measured at 1 meter from the
speaker in an anechoic environment.
3. Maximum SPL
Full-bandwidth pink noise is applied to the loudspeaker with its active equalization curve and
amplified to a level at the loudspeaker terminals
corresponding to the long-term rated power
handling of the speaker. The average sound
pressure level (dB-SPL) is measured at 1 meter
from the speaker in an anechoic environment.
4. Frequency range
Sine waves are injected into the loudspeaker, and
the level is adjusted to 1 watt, as referenced to
the nominal impedance, and the level measured
at 1 meter. Resulting graph is smoothed by 0.05
octave-band.
