Basketball Court

Enhanced Court Coverage

A typical 120-foot by 100-foot gymnasium with a 28-foot height to the low steel (bottom of trusses).
The bleachers are up to 14 feet tall.
The bleacher loudspeakers are mounted about 20 feet in front of the first row.
Bleachers longer than 70 feet can require four (4) or more loudspeakers per side.
The court loudspeakers provide enhanced coverage to the court for higher speech intelligibility and allow more zone control to accommodate multi-purpose events.
Six (6) R.5-94Z (bleacher coverage)
Eight (8) R.25-94Z (court coverage)
Good pattern control and moderate SPL in non-acoustically treated spaces for the bleachers, court and floor seating.
Six (6) R.35-3896 (bleacher coverage
Eight (8) R.35COAX (court coverage)
Less low frequency extension, but excellent voice clarity with moderate SPL for all areas.
Six (6) R.5-96MAX (bleacher coverage)
Eight (8) R.5-99Z (court coverage
Increased musicality, high SPL, and great pattern control across all listening areas.



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




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.




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.
