R1 SERIES Weather-Resistant, High-Fidelity, Full-Range Loudspeaker Systems Owner's Manual
COMMUNITY PROFESSIONAL LOUDSPEAKERS A TRADITION OF EXCELLENCE AND INNOVATION Since the founding of our company in 1968, Community has been a constant developer and innovator of loudspeaker technology. Many of our engineering achievements were undertaken to solve problems, when no prior solutions existed. Others resulted from simply seeing a better way to do things. Over the years our technologies have been imitated, and our methods have become common practice throughout the professional sound industry.

COMMUNITY R1 SERIES OWNER’S MANUAL 1. IMPORTANT SAFETY INFORMATION Always follow these basic safety precautions when using or installing R-Series loudspeakers and accessories: Read these instructions. Keep these instructions. Heed all warnings. Follow all instructions, particularly those pertaining to rigging, mounting, hanging and electrical connections. Only use accessories that are specified and approved by the manufacturer.
2. INTRODUCTION OF R-SERIES 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 manual is intended to help you install and use R-Series loudspeakers safely and effectively. It provides useful information to help you obtain the best performance, sound quality, and reliability from your R-Series systems.
3 UNPACKING AND INSPECTION Unpacking and Inspection R-Series loudspeakers are inherently rugged and are carefully packed in sturdy cartons. However, it’s wise to thoroughly inspect each unit after it has been removed from the packaging, as damage could occur during shipping. Shipping Claims Please note that once the shipment has left your dealer or the Community factory, the responsibility for damage is always borne by the freight company.

FIGURE 1: Physical Features 4 PHYSICAL FEATURES (See FIGURE 1) MOUNTING / RIGGING POINTS DESCRIPTION Five, 4 on around the sides and 1 on rear. 1/2-13 captive zinc plated inserts with 1/2-13 x 1-1/4 in. SS bolts, lock, flat, and rubber washers. Used for attaching the R1YOKE mounting bracket or customer-supplied mounting system. MOUNTING / RIGGING POINTS OTHER MOUNTING POINTS The grille assembly is retained by 16 #6 self-tapping SS Phillipshead screws.
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.
5.6 WEATHER-STOPTM GRILLE (Grille information does not apply to BNG models) Each R1 enclosure is fitted with Community’s proprietary three-layer Weather-Stop™ protective grille. The grille consists of a corrosion-resistant outer layer of perforated steel with a proprietary zinc-rich epoxy dual-layer powder coat finish in light grey, a center layer of UV-resistant reticulated foam, and an inner layer of fine-mesh screen made from a UV-resistant synthetic material that blocks rain and fights rusting.
7 ELECTRICAL INSTALLATION 7.1 CONNECTING THE LOUDSPEAKER All R2s have approximately 12 ft (3.6m) of 16-2 SJOW-type neoprene jacketed cable attached to the enclosure with a weather-tight gland-nut. This is used for the input signal. This cable may be interconnected to the amplifier output cabling using solder, a terminal block, or wire-nuts. Be sure to provide the connections with a weather-resistant treatment if used outdoors.
7.2 SIGNAL PROCESSING 7.2.1 High-Pass (Low Frequency) Filter The R1s use a horn-loaded low frequency driver. The specified low frequency response is 90 Hz. Any attempt to reproduce significant levels below this frequency can result in over-excursion of the low frequency drivers. For this reason an electronic high-pass filter set for 80 to 90 Hz must be used. The slope should be a minimum of 12 dB per octave.
8.1.1 ACCEPTABLE MOUNTING POINT LOADING The mounting points should be always be used so that either shear force is applied perpendicular to the direction of and in tight proximity to the mounting hole or tension force is applied perpendicular to the enclosure surface. DANGER: Use the mounting points only as described above and shown in FIGURE 2. Do not use them in such as way as to apply sideways leverage to them.
8.2.1 THROW DISTANCE AND SOUND LEVELS The chart below helps answer the question, “how far can it throw?” The chart shows the maximum distance at which a given model can reach 96 dB SPL on the A Scale (speech range). Consider a high-school football stadium where the crowd noise is 86 dBA. At the recommended distance, an R.25 or R.5 would provide 10 dB headroom above the crowd noise. Even if the crowd noise reaches 90 dBA, the R.25 or R.
CAUTION: The R1 Mounting Yoke is specifically designed to provide a high degree of safety in R1 installations. It is highly recommended for mounting an R1. Other mounting methods should be carefully considered so that undue strain and possible failure of the mounting points does not occur (See SECTION 8.1.
8.3.2 R1YOKE MOUNTING PROCEDURE (See FIGURE 3) Normally the yoke should first be attached to the R1 then the entire assembly mounted to a structure. However in some cases it may be desirable to mount the yoke and secure it in place before mounting the R1 to the yoke. Depending on the situation the sequence of the following mounting procedure may have to be modified to facilitate the work. Nonetheless, the instructions and precautions about use of the hardware should still be followed.
8.4 WEATHER RESISTANCE (Grille information does not apply to BNG models) All R1s are highly weather-resistant by design. The all-fiberglass enclosure is virtually impervious to the effects of weather. The grille is designed to prevent rain intrusion into the mouth of the loudspeaker.
application. Prior to installation, the contractor should present a rigging plan, with drawing and detailed parts list, to a licensed structural engineer (P.E.) or architect for written approval. 9 OPERATING PRECAUTIONS 9.1 LIMITING Although R1s have built-in PowerSense™ DDP circuitry to help prevent damage to the drivers from excessive power, electronic limiting is strongly recommended.
10 SERVICING 10.1 Tools Required for Servicing #2 Phillips head screwdriver 11/32 in. Wrench or nut driver (crossover) 7/16 in. Wrenches or nut drivers (HF horn brackets) 10.3 High Frequency Driver The high frequency driver has a field replaceable driver/voice coil assembly. The high frequency horn/driver assembly is retained by brackets secured to the inside of the bass horn and eyebolts secured to the LF driver. To remove the driver, first remove the grille.
