PRODUCT OVERVIEW
JL Audio Fathom IWS subwoofers combine a state-of-the-art
JL Audio subwoofer driver and electronics/amplier package with a highly
optimized enclosure to deliver an exceptional listening experience in your home
theater or home audio system.
e subwoofer driver in your Fathom subwoofer system is capable of
outstanding linear excursion without distress or audible distortion. is
reference-quality driver enables your Fathom to reproduce powerful low
frequency events with stunning impact and unprecedented accuracy.
To get the most from this long excursion driver platform, prodigious amounts
of controlled power are needed. Our electronics engineering team conducted
an intense analysis of typical program material and its dynamic demands in
order to balance current draw and actual output power requirements relative to
the system’s impedance characteristics. Aer careful study, a pair of precisely
engineered switching ampliers employing patented feedback technology
were created. ese advanced designs are capable of unclipped output voltages
equivalent to 1000 watts (System 1) and 2000 watts (System 2) of RMS power
when referenced to the nominal loudspeaker impedance, allowing us to take full
advantage of each driver’s full excursion envelope.
e beautiful cabinet enclosing the workings of your Fathom is also the result
of careful engineering. To contain the pressures created by the Fathom driver,
we utilized CNC-cut, cabinet-grade baltic birch plywood with extensive internal
bracing features and advanced assembly techniques.
Your listening room is the other enclosure that aects the way your bass will
sound. All rooms create a specic sonic signature, which must be eectively
managed to achieve well-balanced low frequency performance. To aid in this
process, the Fathom includes an extensive set of signal processing tools aimed
at optimizing your Fathom’s performance within your listening space. ese
features include JL Audio’s exclusive Automatic Room Optimization system.
As you can see from this brief introduction, there is a lot of technology in
this in-wall subwoofer. e contents of this manual will explain the features,
guide you through the setup and tuning of your Fathom subwoofer and help you
achieve your ultimate low-frequency listening experience.
If you require assistance, we urge you to contact your authorized
JL Audio retailer for expert setup advice and service.
