Football Field

Press Box

The loudspeakers are mounted on the roof of a press box, preferably at least 16 feet above the highest row of seating.
 
The bleachers are assumed to be 20 feet tall at the back row.
 
An array of two to four loudspeakers to address the home seating, plus an R2-52Z or R2-52MAX in the center to provide crossfield coverage.
One (1) R2-52MAX (visitor coverage) 
Three (3) R.5-96MAX (home coverage) 
 
High SPL and best musicality. Addresses larger bleacher areas while projecting uniformly over farther distances.
One (1) R2-52Z (visitor coverage)
Two (2) R.5-94Z (home coverage) 
 
Moderate SPL for use in venues with shorter bleachers (i.e., the length of the bleachers does not exceed the 30-30 yard line).
One (1) R2-52Z (visitor coverage) 
Two (2) R2-94Z (home coverage) 
Two (2) R.5-94Z (center of home) 
 
Very articulate three-way performance and enhanced LF to the home seating section, while providing more even coverage to wide sections of the home stands.

AMPLIFIER

 

For maximum system performance and longevity, the loudspeakers must be properly powered to achieve the needed sound pressure level (SPL) in the listening area.

 

R.25-94Z: 400W to 600W @ 8 ohms per loudspeaker
R.35COAX: 400W to 600W @ 8 ohms per loudspeaker
R.35-3896: 800W to 1200W at 8 ohms per loudspeaker
R.5-66Z: 400W to 600W @ 8 ohms per loudspeaker
R.5-94Z: 400W to 600W @ 8 ohms per loudspeaker
R.5-99Z: 400W to 600W @ 8 ohms per loudspeaker
R.5-96MAX: 1200W to 1800W at 8 ohms per loudspeaker
R2-94Z: 800W to 1200W at 4 ohms per loudspeaker
R2-52Z: 800W to 1200W at 4 ohms per loudspeaker
R2-52MAX: 1200W to 2400W at 8 ohms per loudspeaker

 

PROCESSING AND PROTECTION

 

To properly process, equalize and protect the loudspeaker systems, it is recommended to use the Community dSPEC226 digital signal processor.

 

Some amplifiers have built-in processing which may be adequate when properly programmed. Community's suggested DSP settings for R SERIES loudspeakers can be found HERE.

 

All of the loudspeakers referenced in this guide require a 24 dB per Octave electronic high pass filter for protection against over-excursion from bass-heavy program material.

 

WIRING

 

When considering the distance between the amplifier and the loudspeaker(s), the following minimum cable gauges are suggested.

 

Less than 50 feet: 14 AWG
50 to 100 feet: 12 AWG
100 to 250 feet: 10 AWG
Beyond 250 feet: Please contact the Community TAG Team

It is strongly recommended that all loudspeaker level wire be stranded, twisted and never shielded.  Loudspeaker wires should not be connected to earth ground or supporting structures.
