THE AMPLIFIER
The Fathom IWS uses a unique amplifier, specifically engineered to
take full advantage of the Fathom IWS subwoofer’s full excursion envelope.
There are two amplifier models, a 1kW amplifier for the System One
and a 2kW version for the System Two. Both are available as either 120V
or 240V AC powered. Besides their output and AC power distinctions,
both amplifiers incorporate specific equalization curves for use with
each particular enclosure type (“A” or “B” box). Refer to the charts below
to verify that you have the correct amplifier for your application.
