Overview
This application note covers the basic concepts for
the application of the Freespace Ds 100se loud-
speakers in business music systems.
The Freespace Ds 100se loudspeakers are ideally
suited to background music, foreground music and
paging applications with mounting heights between
8 and 32ft (2.4 to 10m). The Articulated Array
composed of two 2.25 inch drivers, delivers consis-
tent response across the entire 180° coverage area.
The 5.25 inch driver, mounted in a ported enclo-
sure, provides the additional bandwidth required
for today's foreground music applications. The
Freespace Ds 100se loudspeakers are compatible
with 70V, 100V and low impedance amplifiers and
are capable of delivering up to 95 dB
application with a 15ft (4.8m), mounting height.
All system designs begin with a set of requirements.
The system requirements can be as simple as "it has
to sound great," or as detailed as "it must have an
output level of 100 dB
." in either case, the chal-
sPL
lenge is to gather the right set of requirements and
convert them into a set of design criteria to use in
creating your design.
The three key requirements that you need to
identify in order to deliver the right business
music sound system are:
Loudness What sound pressure level is required
for this application?
Response What bandwidth is required for the
type of program material that will be used?
CoveRage How consistent must the sound be
across the entire coverage area?

Long Term Power Handling

each of these requirements can be easily converted
into a specification that we can use to create our
system design. if we understand the customer's
needs in these three areas, we can deliver a design
that will, at a minimum, meet their needs, and at
best, exceed their expectations.

For the purposes of this application note, we will
™
assume that you are familiar with the system
requirements for a business music system and are
ready to focus on the creation of a speaker layout
using the Freespace Ds 100se loudspeakers.
Design Guidelines
When creating a design that uses the Freespace Ds
100se loudspeakers, you should consider the following:
in a typical
sPL
•
The Freespace Ds 100se loudspeakers are ideally
suited to background music, foreground music
and paging applications.
• Recommended mounting height for the FreeSpace
Ds 100se is between 8 and 32ft (2.4 and 10.0m).
• Provide at least 20ft (6.1m) of space between
adjacent loudspeakers for typical applications.
• In outdoor applications do not space the loud-
speakers by more than 50ft (15.2m).
• Generally, the FreeSpace DS 100SE should be
pitched downward between 0° and 15°.
• Maximum SPL for a typical application is between
89 and 98 dB
• Always add 25% headroom to your amplifier to
accommodate various types of program material.
