The LOOP THRU output is an output XLR in
parallel with the input connector and is useful for
daisy chaining the input signal to a number of
boxes, connecting them in parallel.
The number of units that can be linked this
way depends on the output impedance of the
equipment driving the enclosure, such as the mixer
or processor. Typically, to avoid signal degradation,
the maximum number that can be daisy chained is
given by the formula (1250/Z), where Z is the
output impedance of the equipment driving the
enclosure. For instance, a 100 ohm output
impedance allows daisy chaining 12 boxes.

Subwoofer level is controlled via the SUB
LEVEL potentiometer. If separate control and
signal routing to the
and is
required (such as for applications where the
subwoofer is run off a console's aux bus as an
effect, or it needs to be delayed), drive each
enclosure model separately from a processor,
using a Linkwitz-Riley 24 dB/octave 100 Hz high-
pass filter for the
(so that the missing high-
pass from the is replicated), feeding the
with full-range signal.
