JL Audio C7-350cm 3.5" Component Midrange with Grille - Single

The C7-350cm component midrange is designed to operate in a 3-way system, with a woofer and tweeter. Conceived and purpose-built from the ground up, it offers exceptional transient response and outstanding linearity, resulting in unsurpassed clarity and natural mid-range reproduction. Distortion and non-linearities have been minimised through critical optimisation of dynamic motor and suspension behaviours.

Passive crossover networks are not included with C7 drivers, as they are designed for active systems. Instead, we recommend a high-quality tuning DSP, such as the JL Audio TwK™ 88 or D8, and a dedicated amplifier channel for each C7 loudspeaker in the system. Precise setup of equalisation, delay and crossover filters will ensure optimal in-vehicle performance.

Cone and Dust Cap

Vacuum-formed, mineral-filled polypropylene material offers excellent damping and low mass. The cone body features a gentle curvilinear profile to optimise response. A concave dust cap further improves high frequency behaviour.

Suspension design

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 excursion.

Motor Design

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 optimised utilising advanced FEA tools to reduce distortion and provide linear motor force throughout the driver's performance range.

A 36 mm (1.42 inch) diameter, overhung voice coil is employed, wound with copper-clad aluminium wire onto a fibre glass voice coil former. The oversized voice coil offers extended power handling capability, minimising thermal compression and distortion at higher listening levels.

Chassis Design

A purpose-engineered cast alloy basket is employed, featuring thin spokes to maximise rear open area.
