62 RMG-200AT For coverage of entire floor area

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

System Cost Estimate - $$$$$

Distributed Line vs. Distributed Ceiling System

A distributed system offers the best way to cover a space like this. It puts the loudspeakers as close as possible to the

listeners and aims them away from the walls and ceiling. A distributed ceiling system would also work well in a space like

this (loudspeakers facing straight downwards). A good choice for that type of system would be an R.5COAX as used in

the Convention Center application on page 52.

For this warehouse application, however, we have chosen an alternate design which uses four rows of horn-type loud-

speakers, facing downwards and outwards. The design starts with two, back-to-back lines of loudspeakers in the center

and continues with two additional rows of loudspeakers at an appropriate distance from the center. These outer rows

must be delayed to match the arrival time of sound from the center rows. This design uses fewer loudspeakers than a

ceiling distributed system and the RMG-200A horn-type loudspeakers provide good control over coverage while maintain-

ing a favorable direct/reverberant ratio.

This design still faces the challenge of blocked sound from shelving that reaches near the ceiling. The only solution to this

problem is to add more loudspeakers.

To reduce cost, consider using one or two RSH-462s (depending on horizontal coverage needed) in place of the

RMG-200As to cover the open area (top right of diagram).
