INTRODUCTION
The SSW 2020 is a stereo passive subwoofer with both direct (4 Ohm) and 70/100V input, and a pair of
highpass outputs for satellite speakers.
80W are available, by connecting to the respective input terminal. Selection between inputs (direct and
70/100V) is carried out with a slide switch.
Also provided is a mode switch which provides stereo mode operation and mono mode operation (in case
of 70/100V input). In mono mode, the subwoofers are connected in series while the highpass output is
available from the left channel only.
Connection to the subwoofer is via Euroblock terminals which greatly facilitates wiring.
protective covers. Please ensure that the following are attached to the rear of the unit.
1. 2 x wall-mount brackets fitted to the rear plate
2. 3 x female headers of Euroblock terminals
Inspect the speaker for any sign of damage. Please retain all packing materials in case you have to transport

MOUNTING
SSW 2020 • page 3
The SSW 2020 comes fitted with wall mount brackets so that you can hang it on the wall. Please follow the
steps given below
The wall mount bracket of SSW 2020 consists of 2 parts - one that is fitted to the cabinet and the other part
a fish-plate and 2 screws, for transit purposes. First open the 4 screws, and remove the plate. Please see
Fig.1 below
Next, drill holes on the wall for the screws
supplied, as per the following diagram, where
you want to mount the SSW 2020. Please see
Fig. 2 below
Now fit the wall mounting brackets to the wall with
the help of the screws supplied. Please see Fig. 3

1. INPUT SELECT SWITCH
This is a slide switch for input selection. When connecting the 4 Ohm speaker output of your amplifier
to the input of the SSW 2020, keep the switch in DIRECT mode. When connecting the 70V or 100V
output of your amplifier, keep it in 70/100V position.
2. MODE SWITCH
This is a slide switch for stereo/ mono mode. If you have connected 2 channels of your amplifier
output to the input of the SSW 2020, keep the mode switch in stereo position. If, however, the input
is mono, as for instance, 70/100V output of an amplifier, keep the switch in mono position. In
mono mode, the subwoofers are connected in series while the high-pass output is available from the
left channel only. Do not connect speaker to right input and amplifier output to right input as this may
cause malfunctioning.
3. DIRECT INPUT
Connect the 4 Ohm speaker output of your amplifier to these terminals. There is a pair of terminals

and the other for right channel. In stereo mode, the impedance of satellite speakers should be 4
Ohm for each channel. In mono mode, the satellite speaker connected to the left channel will only
