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
