Community R-Series Application Guide — Page 4

INTRODUCTION

Community’s R-Series is a high-quality, high-fidelity product line designed to be highly weather-resistant. R-Series products

perform consistently in continuous outdoor exposure while simultaneously providing superlative acoustic performance.

This Applications Guide discusses a variety of applications for R-Series loudspeakers. For each type of facility, we have

provided two or three different example designs with discussions about the merits of each design. Although the specific

facilities in this Guide are fictional, the designs shown are representative of typical R-Series applications and should be helpful

in designing sound systems for similar facilities.

Community emphasizes that these examples were created as guidelines only. They are not intended to be finished

designs and may or may not be suitable for specific projects. For a specific project, Community recommends the

services of a qualified acoustical consultant or design/build contractor.

For specific projects, Community’s TAG Team (Technical Applications Group) can provide additional product and applications

assistance and Community’s web site has additional resources including an “All-Weather/All-Purpose” Brochure describing all

R-Series and Wet Series II Models.

A DISCUSSION OF WEATHER-RESISTANCE

Weather-resistant is a relative term that describes a loudspeaker’s ability to resist the effects of weather in outdoor

applications. Typical weather-related damage encountered in loudspeakers affects the enclosure, drivers, hardware, and

internal components such as crossovers.

Community’s R-Series enclosures are fabricated entirely of hand-laminated fiberglass, or roto-molded gray polyethylene,

making them virtually impervious to weather-related effects. Fiberglass versions are coated with an attractive, light gray gel-

coat to help keep the loudspeaker cooler in sunlight. High-frequency drivers and their diaphragms are made of highly weather-

resistant materials. Midrange and low frequency cones are treated to repel moisture. All external hardware on the

loudspeaker is high-grade steel or aluminum with a weather-resistant, powder-coated finish. The grille is backed with a layer

of open cell foam supplemented by a fine mesh plastic to block rain or snow. This grille “sandwich” is acoustically transparent

but highly resistant to even driving rain. The perforated metal grille also keeps out insects and birds. There are no connectors

on an R-Series loudspeaker. Instead, a highly weather-resistant type 12’ (3.6 m) 16-2 SJOW cable is permanently attached to

the loudspeaker through a weather-tight gland nut. This connection is far superior to any exposed connector.

DESCRIPTION OF THE R-SERIES

All-Weather/All-Purpose

Though designed to handle the harshest outdoor conditions, R-Series is the perfect choice for many indoor environments.

With 22 models to choose from, ranging from short throw with wide coverage angles to ultra-narrow, long throw systems,

the task of designing an acoustically and economically effective sound system has never been easier. In many cases, a small

number of R-Series loudspeakers can provide top quality sound for a surprisingly large physical area, making them one of the

most acoustically and economically effective solutions available anywhere.

R-Series Applications

R-Series products are designed for permanent installation or portable use both outdoors and indoors. The primary

applications for Community’s R-Series are those where re-entrant horns, outdoor two-way horn/woofer loudspeakers, and

some larger horn loudspeakers typically are used but lack capability for both high quality music reproduction and longer

distance voice projection. By contrast, R-Series products have excellent fidelity and wide frequency range for both music

reproduction and voice projection.

R-Series products are ideally suited for athletic fields (football, soccer, baseball, tennis) and field houses, theme parks,

amusement parks, swimming pools, ski slopes, cruise ships, steeple carillons, fairgrounds, rodeos, small arenas, racing tracks,

air shows, skating rinks, convention centers, factories, warehouses, and portable sound systems. They can complement

Community WET Series II products for projects needing a combination of both longer and shorter-throw applications.
