The S100 subwoofer has a wide variety of features, including:
Dedicated volume control
Switch able phase control
Variable low pass crossover (40 Hz to 240 Hz)
Auto turn-on
High and low level inputs
Switch able power supply (110/220V user selectable)
The cabinet of the S100 uses 19 mm thick high-density composite walls . The cabinet is finished in a high gloss
acrylic piano black finish .
The amplifier is a 100W RMS/200W peak class A/B design . It is not a switching/class D amplifier, and as such has a
very low noise floor . It features a large power transformer, oversized power supply capacitors, and a large external
aluminum heat sink to ensure longterm cool operation .
The driver is a very long throw 20 cm diameter driver with a 38 mm diameter voice coil, heavy gauge cast aluminum
basket, 2500-gram motor system with a 1000-gram magnet, epoxy-reinforced paper pulp cone, and progressive
fabric spider . It features a patent-pending XBL
36 mm of peak-to-peak excursion . The linear motor strength curve from this motor ensures extremely low distortion
and compression over the full operating bandwidth, as well as a very high transient response .

4.1 Control Panel

The control panel of the S100 is labeled for easy identification and use . The most commonly adjusted controls are
located the top of the amplifier, while the least accessed connections are located at the bottom .
The volume control allows setting the gain of the built-in amplifier to match your main speakers . A total range of
60 dB is provided, allowing integration with nearly any audio system .
Phase can be switched between 0 and 180 degrees . Phase adjustment is critical to get proper subwoofer/speaker
integration .
The crossover frequency has a roll-off range from 40 Hz to 250 Hz . For use with Final Sound electrostatic panels the
crossover is typically set to the lowest frequency the panel can reproduce .

4.2 Connections

The auto-on switch will place the amplifier in low-power mode until an input signal is detected on the low or high-
level inputs . When an input signal is detected the amplifier will automatically turn on, and will stay on for approxi-
mately 10 minutes after the input signal is removed .
The line level inputs are standard RCA connectors, and are compatible with all consumer electronics . The amplifier
will automatically sum the two input signals together to create a mono bass signal . In the event an LFE/SUB-OUT
signal is fed to the subwoofer, either line level input may be used .
The high level inputs are 3 way binding posts, and are compatible with all consumer amplifiers . The input impedan-
ce of the high level inputs is high enough to not draw significant amounts of power or load down the output of any
power amplifier . Small gauge wire may be used to provide the input signal .
The power connection is a standard IEC connector with a built-in fuse holder . The power supply cord must be
plugged into the connector before the power supply cord is plugged into the wall socket .
The fuse is contained inside the IEC connector . The small tab inside the connector must be depressed allowing the
fuse holder to be slid out . The power supply cord cannot be used when the fuse holder is extended or removed .
