The SSW-351 contains a built-in crossover network.
There are several ways in which an additional speaker can be connected to the SSW-351.
Since the HIGH FREQ OUTPUT is routed
through the internal crossover network,
a signal from which the low range has
been cut will be sent to the connected
speaker.
In this case, the combined impedance will be 8
ohms.
The PARALLEL INPUTS can be used as an
output to connect an auxiliary woofer or
a full range speaker. A full frequency
range signal will be sent to the
connected speaker.
In this case, the combined impedance will be 4
ohms.
A method to increase low-range sound pressure
levels.

The speakers can be driven by multiple
amps very simply with the internal
crossover network. When driving the
speakers with two power amps (bi-
amping), connect the speakers using the
parallel input jacks.
The volume balance between the subwoofers (SSW-
351) and full-range speakers (SST-151/251) and be
adjusted with the power amp level settings.
Using two power amps provides greater headroom
when driving the speakers.
If you wish to use an external channel
divider (crossover network) instead of
using the built-in crossover network,
make connections to the DIRECT INPUT.
Pay attention to the crossover frequency
of each speaker that is connected.
Carefully read the specifications before
connecting an external channel divider
(crossover network).
For the crossover frequency, we recommend
frequencies between 100 Hz and 200 Hz.
