Based on cost comparison scale: $ = lower cost, $$$$$ = higher cost

System Cost Estimate - $$$$$

Point-Source System

A point-source system is usually the lowest-cost option for any facility. The point-source system in this example will pro-

vide ample level and excellent musical sound quality with acceptable voice intelligibility. In comparison, the Ceiling Distrib-

uted design (Indoor Ice Rink System #1) will provide better voice intelligibility and more flexibility for multipurpose use at

somewhat higher cost.

Multi-Purpose Usage

The center-mounted loudspeakers will provide adequate floor coverage for non-ice-rink usage but this system is not

designed for uses where an audience is sitting in chairs on the floor.

Alternate Loudspeaker Choices and 70/100 Volt Systems

The R2 loudspeakers used in this example are high-power devices that can easily produce “rock ’n’ roll” levels in large

gymnasiums. When level requirements are lower, consider the Community R1 loudspeaker series which offers excellent

pattern control at a lower price.

Add R2SUBZ loudspeakers for extended low frequency response when students want “rock ’n’ roll” musical performance.

Mount the R2 subwoofers over the audience seating areas and apply signal delay to synchronize the R2SUBZ’s output with

the Point Source System’s signal arrival. Refer to High School Gym design #3. Accessory 70/100-volt transformers are

available for R2 loudspeakers. However, if wire runs are short enough, it may be possible to eliminate the transformers

and reduce the system cost. Choose amplifiers that are rated for the resulting low impedance load. This example also

shows an optional pair of R.5 loudspeakers used to cover end-zone seating.
