Overview

In rooms with lower ceilings it is best to project sound from a central ceiling cluster or a set of distributed ceiling speakers. In order to minimize reverberation it is important that sound not be directed squarely at walls and windows. The ideal sound system employs a single loudspeaker. Unfortunately, a single loudspeaker will not always adequately cover all room shapes and sizes. In larger or longer rooms, multiple loudspeakers can be used to achieve even sound. When using multiple loudspeakers, careful attention needs to be paid to keep loudspeaker patterns from interfering with each other. The DRQ™ Ceiling Speaker system uses four distributed speakers, directing the sound in a downward pattern that minimizes inter-speaker interference and produces even sound.


Application

The DRQ™ is ideally suited for classrooms with suspended ceilings that are lower than 12 feet. It is used in the following room configurations:

• A standard DRQ™ system mounted in a relatively square room will cover up to 1600 square feet.
• An expanded DRQ™ system mounted in a long rectangular room will cover up to 2400 square feet, unless the room is more than 60 feet long.
