EdgeMax EM90 Systems
This design worksheet covers the basic steps for the creation of a system design comprised of
EdgeMax EM90 in commercial audio/ business music systems EdgeMax EM90 loudspeakers
are ideally suited for background/foreground music applications with mounting heights
between 2 4 to 6 1 m (8 and 20')
EdgeMax loudspeakers utilize a two-way design comprised of a compression driver mounted
in a proprietary PhaseGuide to deliver asymmetrical high frequency coverage, and an
8-inch driver mounted in a tuned, ported enclosure EdgeMax loudspeakers are compatible
with 70/100V and low-impedance amplifiers, and can deliver up to 98 dBSPL in a typical
application with a 4 9 m (16')ceiling height
The design process described within this document uses three key requirements for the
creation of the design, these are:
1. Loudness: What sound pressure level is required for this application?
2. Coverage: How consistent must the sound be across the entire coverage area?
3. Response: What bandwidth is required for the type of program material that will be used?
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 design guide, 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 EdgeMax loudspeakers

Design Guidelines

EdgeMax loudspeakers provide an asymmetrical vertical coverage, and either 90 or
180-degree horizontal coverage The design guidelines presented here offer two coverage
quality options – Premium and Standard
