Arraying
The 650-R2 Subwoofer adds very well in arrays. Because
of the long wavelengths of low frequencies, small 650-R2
arrays will tend to be essentially omnidirectional. Larger
arrays may be constructed, however, which can provide
the directional control required to project the low-frequency
energy forward efficiently.
Some examples of such arrays are shown in the illustra-
tions below. Line arrays of 650-R2’s, either vertical or
horizontal, have been used effectively in many concert
systems for both indoor and outdoor reinforcement. Arrays
exceeding 10 feet in their primary (longest) dimension can
provide 180° or tighter coverage angles (-6 dB points). A
horizontal array can be curved on a 10-foot radius to
tighten the coverage further. Hybrid arrays may be formed
combining both horizontal and vertical line elements.
A unique circular array is also shown. Arranged in a suit-
able mounting frame with a full-range loudspeaker system
rigged in the center, this array provides very good projec-
tion characteristics. It has been used successfully in theme
park applications.
