The Ceiling Speaker Systems – An Overview
The EVID ceiling system product line provides premium-level performance at a value
price. Their wide coverage and high SPL capability allows the use of fewer speakers,
resulting in lower system cost than the tight-spaced layout that low power narrow
coverage speakers require. The overall price differential of the EVID units to commodity
type speakers is actually quite small when the assembly and component costs of these
standard ceiling speakers is taken into consideration. The EVID units are fully assembled
and no additional installation components are generally needed. An EVID system “pays
for itself” very quickly. Locations with the highest sales per square foot are the ones who
are most careful about sound quality, music programming, and customer satisfaction.

VALUE OF PREMIUM PERFORMANCE:
People are getting used to better quality sound in their homes, cars and entertainment
spaces. Their expectations have grown for better quality sound in retail, office and other
background music spaces. Using premium quality audio systems can help increase sales
through improved customer perceptions of the business’s products or services. It has
now been well established that the quality of music in commercial spaces greatly impacts
the customer’s perceptions of the products or services of the establishment. The dollar
payback is substantial. High quality music also increases the friendliness and job
satisfaction of the employees.

A Unique Solution to an Age Old Problem
High ceilings and reverberant rooms have long been the downfall of many ceiling based
distributed sound installations. The inherent desire for wide dispersion in smaller
acoustically dead spaces works against the use of ceiling speakers in larger rooms with
reverberant characteristics and higher ceilings. Until now there has not been a cost
effective solution that combines good quality full range audio with useful pattern control.
Some ceiling products attempted to have pattern control at the high frequencies but this
proved largely ineffective at the critical voice spectrum of the audio range. The result
was a speaker that had the same poor intelligibility problems when used in reverberant
room as conventional ceiling speakers.
The real solution to the problem requires that directionality must exist for the critical mid
frequencies as well as the upper end of the spectrum. For this to happen a new approach
is needed.

The EVID Solution – Why is it Different?
The EVID C8.2HC – Wide spectrum Pattern Control in a Compact
Package
Package
The EVID C8.2HC is designed to provide directionality through the critical voice
spectrum by employing a unique (patent pending) ported waveguide to the entire 8”
driver. The resultant package is one that is compact, easy to install and provides far more
intelligibility in reverberant or high ceiling environments than any other competitive
model. The C8.2HC also is designed for higher power, high SPL applications with a
