Resulting from an equal and opposite reaction to the cone's
movement, strong bass causes all traditional subwoofer
enclosures to generate acoustic vibrations. You feel this by
touching the cabinet. Although the "physics" of this phe-
nomenon actually cause a subwoofer cabinet to resonate
or even dance, most subwoofer designers apply weight or
mass to the cabinet to minimize such disturbances, but still
leave one by product—"smeared bass". Vibrations translated
from the woofer to the cabinet actually dampen the bass
signal causing a loose and "fuzzy" sound.
The Descent i integrates BalancedForce bass configura-
tion to nullify cabinet vibrations. Originally engineered for
the cost-no-object, state-of-the-art Statement™ E2 system,
BalancedForce uses two or more drivers mounted at oppos-
ing angles. The Descent i's 3 drivers, spaced 120 degrees
apart, operate in exact opposition, resulting in maximum
cancellation delivering the ideal—pure bass energy with a
reduction in cabinet contributions to the room as high as
25dB over traditional subwoofer resonance solutions!
TriLinear™ Configuration
The use of three small, identical drivers maintains the low
distortion levels and optimal control of an efficient and
rigid small driver while moving the same amount of air as
a driver three times larger. This allows powerful bass in a
small package, free from the performance limitations of a
heavy and hard to control single large driver.
Servo-Controlled Dynamic Drivers
All dynamic drivers generate distortion caused by spider
and surround nonlinearities as well as voice coil inductive
disturbances and variant motor strength during massive
woofer excursions. These challenges plague all subwoofer
designers. The result? Induced harmonic and intermodulated
distortions causing dramatic disturbances at high excursions.
This occurs significantly in almost all non-servo-controlled
subwoofers.
MartinLogan’s advanced servo system uses a sophisticated
monitoring and control circuit to detect and instantaneous-
ly correct any deviation between acoustical output and
electrical input. The result? A reduction in distortion for
the purest possible low-frequency reproduction.
Proprietary Switching Amplifier
The Descent i incorporates three identical proprietary
switching amplifiers.The use of three amplifiers allows
for an incredible amount of woofer control resulting in
tighter, better defined bass while keeping distortion at the
lowest possible levels.
25Hz & 50Hz Level Control
The Descent i 25Hz & 50Hz Level controls allows custom
sound tailoring capabilities found in few subwoofers. A
room, especially when small, can greatly exaggerate bass
in the 20–60Hz range. The Descent i’s 25Hz & 50Hz
Level control knobs increase or decrease lower bass to
compensate for these room anomalies and allow increased
deep bass if you desire a subsonic sense of energy at the
lowest frequencies.
