Congratulations! You have invested in one of the
world's premier subwoofers .
The MartinLogan Depth i represents the culmination
of an intensive, dedicated research program directed
toward creating a world class reference subwoofer using
advanced technologies and without compromising dura-
bility, reliability, craftsmanship or aesthetics.
The Depth i subwoofer uses three custom 8-inch high-
excursion drivers in a BalancedForce™, TriLinear™
configuration, which dramatically reduces cabinet
vibrations, allowing deep, tight, well-defined bass.
Servo-control woofer technology minimizes distortion. A
proprietary digital amplifier drives the output stage with
precision and extremely high efficiency. Low-pass filtering
and phase control have been designed to make integrat-
ing the Depth i subwoofer with both MartinLogan and
non-MartinLogan products both seamless and simple.
The materials in your new Depth i subwoofer are of the high-
est quality and will provide years of enduring enjoyment and
deepening respect. The cabinetry is constructed from the
highest quality composite material for acoustical integrity.
This User's Manual will explain in detail the operation of
your Depth i subwoofer and the philosophy applied to its
design. A clear understanding will help you obtain maxi-
mum performance and pleasure from this most exacting
subwoofer system.
