DESIGN & TECHNOLOGIES
Cone and Dust Cap:
1
Vacuum-formed, mineral-filled polypropylene
material offers excellent damping and low mass.
The cone body features a gentle curvilinear
profile to optimize response.
2
A concave dust cap further improves high
frequency behavior.
Suspension Design:
3
The moving assembly is suspended and
damped via a linear profile spider formed from
a Nomex®/polycotton blend, and a positive-roll,
rubber surround. The two combine to provide
optimum damping without prematurely
restricting the C7-350cm’s excursion capability.
Motor Design:
4
The C7-350cm employs a high-density magnetic
circuit with a high-grade, neodymium magnet,
and a specially machined, U-Yoke motor
topology. Motor magnetics have been precisely
optimized utilizing advanced FEA tools to
reduce distortion and provide linear motor force
throughout the driver’s performance range.
5
A 36 mm (1.42 inch) diameter, overhung
voice coil is employed, wound with copper-
clad aluminum wire onto a fiberglass voice
coil former. The oversized voice coil offers
extended power handling capability,
minimizing thermal compression and
distortion at higher listening levels.
Chassis Design:
6
A purpose-engineered cast alloy basket is
employed, featuring thin spokes to maximize
rear open area, and our Patented Elevated
Frame Cooling technology.

INTRODUCTION
Thank you for choosing JL Audio C7 loudspeakers
for your automotive sound system. C7 is the
pinnacle of JL Audio loudspeaker design, benefitting
from patented technologies and our most advanced
development tools.
The C7-350cm is a component midrange
designed to operate in a 3-way system, with a
woofer and tweeter. It offers exceptional transient
response and outstanding linearity, resulting
in unsurpassed clarity and natural mid-range
reproduction. Distortion and non-linearities have
been minimized through critical optimization of
dynamic motor and suspension behaviors.
We do not recommend the use of passive
crossover networks with C7 loudspeakers. Instead,
we recommend a high-quality tuning DSP and a
dedicated amplifier channel for each C7 loudspeaker
in the system. Precise setup of equalization, delay
and crossover filters will ensure optimal in-vehicle
performance.
Should you have any questions regarding the
instructions in this manual, please contact your
authorized JL Audio dealer for assistance, or contact
the JL Audio Technical Support Department.
