Community R-Series Application Guide — Page 5

R-Series Indoor Applications

R-Series and WET Series II loudspeakers are great indoor loudspeakers. These models are ideal for humidity-prone

environments like gymnasiums and swimming areas. Selected models are available in specially-designed indoor versions without

the weather-resistant grille. Where likelihood of splashing (indoor water park) or physical abuse (gymnasium) is possible,

Community recommends the standard R-Series model with the grille.

R-SERIES FEATURES

R-Series products are entirely constructed of corrosion-resistant materials like fiberglass, powder-coated steel or aluminum,

non-metallic and carbon fiber, using sophisticated technologies to ensure they will withstand exposure to harsh environmental

conditions.

Weather-Resistant LF Cones and HF Diaphragms

All R-Series models feature weather-resistant LF cones and HF diaphragms.

Ferrofluid

Most LF, MF & HF drivers use Ferrofluid in their voice coil gaps. Ferrofluid provides improved heat transfer resulting in higher

power handling, reduced distortion from fluidic dampening of mechanical resonance, and it seals the air gaps against corrosion

and oxidation.

Driver Protection

Functioning as a limiter, Community’s exclusive DYNA-TECH™ protection circuitry found in many R-Series models provides

precise and repeatable protection by reducing excessive power to the drivers. In other models PowerSense™ DDP (Dynamic

Driver Protection) protection circuitry is built into the crossover to provide protection against excessive current.

Fiberglass or Polyethylene Horns and Enclosures

Horns and enclosures on larger R-Series models are constructed of hand-laid fiberglass. Fiberglass is inherently weather-

resistant while exhibiting the strength, stiffness, and non-resonant characteristics needed to insure an acoustically inert

loudspeaker enclosure. Enclosures and horns for the R.5 and R.25 models are attractively molded from highly weather-

resistant polyethylene.

The unique curved shape of R-Series and WET Series II helps reduce standing waves within the enclosure for improved LF

performance. Outdoors, the rounded shape inhibits standing water and helps to diffract wind, which in turn reduces the wind

load on the supporting structure.

Horn Technology

Community is the originator and master of fiberglass horn manufacturing. The horns used in many WET Series II and R-Series

loudspeakers are constructed as one-piece, precision waveguides by hand-crafting on a precision mold using 100% hand-

laminated fiberglass. Balsa wood is embedded and laminated into the fiberglass at strategic points to create extremely strong,

double wall constructions which damp vibrations providing clean, resonant-free sound. In compact R-Series models, the horns

are constructed of high density polyethylene with reinforcing ribs to dampen vibrations. Perforations in the horn reduce

reflections from the LF driver while still providing optimum pattern control and acoustic loading for the high frequency driver.

Weather-Stop™ Grille

Each enclosure is fitted with Community’s proprietary Weather-Stop protective grille. The grille consists of an external

perforated, powder-coated steel panel, followed by a layer of open cell foam, and an inner layer of fine mesh plastic. This grille

assembly prevents water intrusion, while providing a high degree of acoustic transparency.

Powder-Coated Steel Hardware

Most hardware and fasteners are made of corrosion-resistant powder-coated steel or stainless steel.

Input Cables

To help maintain its weather-resistance properties, there are no connectors on an R-Series loudspeaker. Instead, input is via

an attached 12 ft (3.6 m) 16-2 SJOW-type neoprene jacketed cable (rated for outdoor use) with a weather-tight gland-nut.
