PRODUCT OVERVIEW
JL Audio Fathom subwoofers combine a state-of-the-art
JL Audio subwoofer driver and electronics/amplifi er package within
a highly optimized enclosure to deliver an exceptional listening
experience in your home theater or home audio system.
Th e subwoofer driver in your Fathom subwoofer system is capable of
outstanding linear excursion without distress or audible distortion. Th is
reference-quality driver enables your Fathom to reproduce powerful low-
frequency events with stunning impact and unprecedented accuracy. Derived
from JL Audio’s legendary W7 design platform, the Fathom drivers off er peak-
to-peak excursion capabilities well in excess of 2.5 inches (63 mm - f110), 3
inches (76 mm - f112), and 4 inches (101 mm - f113) to comfortably handle the
dynamics of the most demanding program material.
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. Aft er careful study, a pair of precisely
engineered switching amplifi ers employing patented feedback technology
were created. Th
ese advanced designs are capable of unclipped output voltages
equivalent to 900 watts (f110), 1500 watts (f112), and 2500 watts (f113) of RMS
power when referenced to the nominal loudspeaker impedance, allowing us to
take full advantage of each driver’s full excursion envelope.
Th 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 solid, CNC-cut, MDF material with extensive internal bracing features
and advanced assembly techniques.
Your listening room is the other enclosure that aff ects the way your bass will
sound. All rooms create a specifi c sonic signature, which must be eff ectively
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. Th
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
compact subwoofer. Th 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.
