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. An effective answer to this problem is the EVID C8.2HC 
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 60watt 70/100v transformer standard.  No other 
ceiling speaker available offers this unique solution. 
The EVID 4.2, 8.2 and 8.2L – Full Range Models with Punch 
EVID C4.2  
Perfect for conventional rooms.  It has excellent 
bandwidth in an esthetically very unobtrusive 
installation profile. It’s compact design fits in tight 
areas.  Fully rated for use in air handling spaces. 
It’s 4” woofer and waveguide coupled titanium 
coated dome tweeter give smooth, wide frequency 
response.  The enclosure is ported and tuned to 
provide surprising bass response in such a 
compact package.  Features an easy 3-point 
mounting system for quick installations.  Comes 
complete with mounting support ring and tile rails.  
No additional accessories needed for most installations.  The C4.2 would be 
ideal for most office spaces along with smaller restaurants and retail space 
where lower volume levels are used.  It fits in close spaces and has a wide 130-
degree dispersion pattern for efficient coverage. 
EVID C8.2  
Unique in providing extremely high fidelity in a flush mount ceiling speaker.  The 
secret is the optimally tuned enclosure coupled to a large 8” coaxial driver.  The 
large enclosure ensures a full bottom end while the waveguide coupled tweeter 
gives uniform coverage for the high frequencies. 
EVID C8.2L  
For tight fitting spaces the 8.2L is the ideal choice.  It is very close to the 
performance of the C8.2 but with a shallow back can for an easier fit.  The 
primary difference is at 50 Hz where the output level is 6db lower than the 
standard C8.2.  In many installations however this is not noticeable and the 
performance of the C8.2L is still far beyond that of nearly any other 8” solution in 
the marketplace. 
The 10.1 - Finally a Compact True Ceiling Subwoofer 
So often ceiling systems had to rely on expensive surface mount 
subwoofers or inadequate ceiling/flush mount options.  In designing 
the 10.1 we started with a mass optimized 10” woofer and a dual 
ported and tuned enclosure.  The internal damping provides 
resonance free performance down to 45Hz.  The system has a true 
crossover to eliminate any “localization” problems and provides the 
proper match to the full range EVID units. 
The C10.1 is also an ideal companion to the EVID surface mount 
speakers.  The C10.1 is an especially good match to the 3.2. 
EV Raw Frame Ceiling Speakers 
EV has provided a wide range of component ceiling speakers for many years.  Contractors have 
come to expect value and performance for every EV model.  Component ceiling speakers are 
often a good solution when specific requirements of the job dictate using an unconventional
