Overview
This application note covers the basic concepts for the
application of the Freespace Ds 16s and se loud-
speakers in business music systems.
The Freespace Ds 16s and se loudspeakers are
ideally suited to background music and paging
applications with mounting heights between 8 and
20ft (2.4 to 6.1m). Compared to other loudspeak-
ers, the 2.25 inch driver used in the Freespace Ds
16s and se provides more consistent coverage in
low and medium mounting height applications. The
Freespace Ds 16s and se loudspeaker is compatible
with 70V, 100V and low impedance amplifiers and
is capable of delivering up to 88 dB
application with a 14ft (4.2m) 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
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?

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 16s and Ds se loudspeakers.
Design Guidelines
When creating a design that uses the Freespace Ds
16s and se loudspeakers, you should consider the
following:
• The Freespace Ds 16s and se are ideally suited to
background music applications. if your customer
requirements are for a foreground music system, you
should consider the Freespace Ds 100se loudspeakers.
• Recommended mounting height for the FreeSpace
Ds 16s and se loudspeakers is between 8 and 20ft
(2.4 and 6.1m).
• Provide at least 20ft (6.1m) of space between
adjacent loudspeakers for typical applications.
• Generally, the FreeSpace DS 16S and SE should be
pitched downward between 5° and 30°.
• Maximum SPL for a typical application is between
85 and 90 dB .

• Always add 25% headroom to your amplifier to
accommodate various types of program material.
