[. . . ] 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 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 and 8. 2 ­ Full Range Models with Punch The 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 3point 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 130degree dispersion pattern for efficient coverage. The EVID C8. 2 is also 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. 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 Basics Selecting & Positioning Ceiling Loudspeakers Several key criteria determine the type and quantity of ceiling speakers to employ in a job. · · · · Room size Coverage density desired Ceiling height Type of audio program material being played There are specific EVID ceiling models for the job depending on the specifics of these criteria. In the traditional approach to overhead-distributed systems, loudspeakers are located in a grid arrangement whose dimensions are dictated by the room height and the directivity of the speaker elements. Two basic placement patterns prevail: square spacing, and hexagonal (or crisscross) spacing. [. . . ] It is important to remember that the C10. 1 works very well with all of the EVID surface mount models also. How large an area can an EVID ceiling system cover? A system consisting of one C10. 1 subwoofer and six to eight C4. 2 or eight C8. 2 satellites can cover up to a 4000 square foot room with balanced, even coverage. The estimate of 4000 square feet is a typical coverage area. You can scale the coverage up or down to adjust for applications with different SPL requirements and different size rooms. What are some techniques to properly balance the levels between the subwoofer and satellites? The required sensitivity balance between the subwoofer and satellites varies by the musical requirements of the application. A sports bar or health club for example might require much more bass content than does a low level background music system. [. . . ]
