WEATHER-STOP GRILLE Each enclosure is fitted with Community’s proprietary 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. -

These points should be taken into account when aiming the loudspeaker. For proper aiming, the R2-694 and R2- 474 loudspeakers will be tilted down about 5 degrees less than a loudspeaker with a symmetrical coverage pattern. Community R2-Series Installation/Operation Manual — Page 10... - Page 11 NOTE: To maintain weather-resistance, the R2 cabinet should be aimed at least 15 degrees below 0° geometric axis.

Page 12: Choosing Power Amplification
There is no external indication of when the protection circuitry is active. For this reason it is strongly recommended as an additional precaution that an external electronic limiter be used prior to the amplifier (See “Operating Precautions”, page 22).

These are recommended insulations: polyethyl- ene, neoprene, Teflon™, Silicon™, and Hypalon™. These insulations are not recommended because of poten- tially shorter life expectancy in outdoor environments: rubber, PVC (polyvinylchloride), polypropylene, polyure- thane, and nylon.

For outdoor installations wind loading must also be taken into account. It is recommended that a qualified and licensed structural engineer approve the mounting design. Figure 4A Community R2-Series Installation/Operation Manual — Page 17... - Page 18 2. Once the position of the yoke is determined, remove two supplied 1/2-13 stainless steel mounting bolts, with the lock, flat, and rubber washers from the mounting points where the yoke is to be attached.

Community does offer in its catalog forged, rated eyebolts intended for rigging loudspeakers. However, these eyebolts are not rated for outdoor use and the shank is too long for the threaded inserts on R.25 and R.5 loud- speakers. -
Page 22: Operating Precautions
L I M I T I N G Community recommends use of a limiter to help prevent loudspeaker damage due to sudden transients (dropped microphones, etc.) or amplifier clipping. When used for this purpose, connect the limiter as the last item in the signal chain before the power amplifier (at the input to the power amplifier). -

(or both). Note that R-Series loudspeakers are factory voiced to optimize their speech intelligibility and musical sound quality. For this reason, many designers find they can minimize overall system equalization and still achieve excellent voice intelligibility and musical sound quality.
