The horizontal pattern also features “soft shoulders” that provide consistent frequency response
to well beyond the nominal -6 dB points. These soft shoulders can provide up to 150° of “usable”
horizontal coverage, albeit at somewhat reduced level. This off-axis performance also provides
good acoustic integration with side-fill arrays. In some cases, these shoulders may be sufficient
for side-fill purposes.
4.2.4 CAF730 Series as Side-fill Arrays
CAF730 side fill arrays can be hung adjacent to the mains, extending the coverage to over 180° for
wrap-around audience coverage.
4.3 GROUND STACKING
Normally, a ground-stacked CAF730 main array is used where suspension is not possible, too
difficult, or too time consuming. Additional uses are as stage side fills and audience front fill.
Both CAF730s and SS730s may be ground-stacked alone or in combination. In combination,
always stack the CAF730s on top of the SS730s. The recommended minimum and maximum array
quantities are:
Array Min Max
CAF730 alone 2 6
SS730 alone 1 4
CAF730 / SS730 2/1 6 / 4
WARNING: Ground-stacked arrays, especially the maximum recommended arrays, requires
assembly by personnel qualified to ensure adequate stability from tip over for the particular
application. See Section 6.8 for correct array assembly. Mechanical assistance will be required to
lift and position enclosures for arrays taller than approximately 5 feet.
4.4 SUBWOOFERS
4.4.1 General Considerations
Although the impressive low frequency performance of CAF730 Series arrays allows them to be
used without subwoofers for some events, subwoofers will normally be used for live musical
performances. The recommended subwoofer is woodworxmax SS730, specifically designed to
complement CAF730 line arrays.
NOTE: Bass performance is often highly program or venue-dependent, as well as subjective as
to quantity and quality. For this reason the type, quantity, and disposition of subwoofers may vary
considerably with the application. The quantity recommendations below are for general purposes,
providing a balanced system for most music applications. Quantities may need to be adjusted up
or down for specific situations.
4.4.2 SS730 Subwoofers
SS730 subwoofers are designed to complement the CAF730 loudspeakers to both extend the low
frequency response and provide more output for the upper low frequencies. The SS730
subwoofers may either be ground stacked, flown as part of a CAF730 array, or flown separately
alongside a CAF730 array.
A general recommendation is to use CAF730s and SS730s in a ratio of three CAF730s to two
SS730s.
4.4.3 Suspending SS730 Subwoofers
The SS730 enclosure rigging is designed to directly couple to a CAF730 Fly-Bar and CAF730
enclosures. As such, the SS730 can be rigged seamlessly with CAF730s.
