5 GENERAL DESCRIPTION
The Community R1 loudspeakers are two-way, coaxial, full-range systems. Completely horn-loaded and with
an enclosure constructed of fiberglass, they are highly weather-resistant, easy to install, and produce very high
output for their size. These unique products are based around a 1 inch titanium HF driver and efficient 12 inch
LF driver to excel at voice projection and full-range, high-fidelity music reproduction. These loudspeakers are
very efficient, have good bass response, and produce high output: 125 dB SPL @ 1m. Additionally, R1’s
provide a useful range of coverage patterns to fit a variety of applications.
5.1 R1xx and R1xx-BNG
The basic R1 models are outfitted for outdoor installations with a light gray gel-coat finish and Weather-Stop™
grille. Models with a “BNG” suffix are provided with a black gel-coat finish and no grille for indoor applications
where weather-resistance is not needed.
5.2 APPLICATIONS
The R1s are designed for permanent installation or portable use both outdoors and indoors.
The primary applications for R1s 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, the R1 has excellent fidelity and range for music
reproduction and voice projection.
R1s are ideally suited for numerous applications: athletic fields (football, soccer, baseball, tennis), athletic 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 also complement Community R2 products for projects
needing a combination of both longer and shorter sound projection.
5.3 DRIVERS
R1 loudspeakers feature a 1 inch exit, 2 inch diaphragm titanium compression driver for HF and a 12 inch
FerroFluid-cooled woofer.
5.4 CROSSOVER
The drivers are acoustically mated through a high quality two-way passive crossover using 250V mylar
capacitors and precision wound coils. The crossover incorporates Community’s proprietary PowerSense™
DDP (Dynamic Driver Protection) circuitry to help prevent damage from excessive input power. The input signal
to the crossover is provided through a 16-2 SJO cable with stripped ends, held captive to the enclosure by a
weather-tight gland-nut.
5.5 ENCLOSURE
The R1 enclosure is a made entirely of hand-laminated fiberglass. An inner low frequency fiberglass horn is
bonded to the outer enclosure shell creating an air chamber between the two that forms the woofer enclosure.
A separate high frequency fiberglass horn is bolted into the mouth of the bass horn. All bolts and screws for
mounting the enclosure, the grille and the mid/high horn assembly are stainless steel.
