Integrating SW-118M
4.1 Integrating SW-118M subwoofer with Tecnare
Loudspeaker Systems
Although the low frequency performance of the most of Tecnare loudspeaker allows them to
be used without subwoofers for some events, it is often necessary to augment mid-high and full-
range loudspeaker systems with subwoofers when higher SPL is needed, or when the program
content requires additional low-frequency energy (for example, for sound reinforcement for live
music performance).
The SW-118M subwoofer can achieve frequencies down to 35 Hz, extending the system
response appreciably and increasing the acoustic power of the system in the lowest
frequencies. Common applications for the SW-118M subwoofer include using it with
CLa208
curvilinear array loudspeakers, as well as using it with
Ibza
or
V Series
loudspeakers.
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.
4.2 Integrating SW-118M subwoofer with CLa208
Curvilinear Array Loudspeaker
When fitted with rigging hardware, SW-118M subwoofers may either be ground stacked,
flown as part of a CLa208 array, or flown separately alongside a CLa208 array, to boost the
system’s low-frequency output and headroom. For flown arrays, the SW-118M attaches to the
THV-118 rigging grid; the CLa208 attach to the bottom of the SW-118M via the TTF208-118
Transition frame, which support both uptilt and downtilt for the flown loudspeakers. When flown
separately, SW-118Ms should be flown so that the spacing between the line of CLa208
enclosures in less than 1 m / 3.3ft.
See the THV-118 and TTF-118 Rigging & Ground stack Instructions for more detailed
information on rigging a SW-118M
The SW-118M extends the low-frequency response of the system by approximately one
octave, as well as provides additional headroom in the lowest octave of the CLa208's range.
A general recommendation is to use CLa208s and SW-118Ms in a 2:1 ratio.
4.2.1
Signal Delay on Subwoofers
If SW-118Ms are flown or stacked with CLa208 as configured in DP-Series Loudspeaker
controlled or T-Series Amplifier, use the factory preset setting.
For other configuration, it will usually be necessary to determine the signal delay setting by
measurement.
