JL Audio JLC7-350CM: 3.5" C7-Series Component Mid-Range Speaker

Design notes:

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 optimize response.  A concave dust cap further improves high frequency behavior.

Suspension design: the moving assembly is suspended and damped via a linear profile spider formed from a nomex / poly cotton blend, and a positive roll, rubber surround.  Both combine to provide optimum damping without prematurely restricting excursion.

Motor design: the JLC7-350CM employs a high density magnetic circuit through 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.

A 36 mm (1.4") diameter, overhung voice coil is employed, wound through copper clad aluminum wire onto a fiber glass voice coil former.  The oversized voice coil offers extended power handling capability, minimizing thermal compression and distortion at higher listening levels.

Chassis design: a purpose engineered cast alloy basket is employed, featuring thin spokes to maximize rear open area.

Features:

• C7-Series is the pinnacle of JL Audio automotive loudspeaker design, benefiting from our most advanced development tools and a complete commitment to precision manufacturing.
• The JLC7-350CM Component Mid-Range is designed to operate in a 3 way system, through 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 minimized through critical optimization of dynamic motor and suspension behaviors.
• Passive crossover networks are not included through C7-Series drivers, as they are designed for active systems.  Instead, we recommend a high quality tuning DSP, such as the JL Audio TWK 88 / D 8, / a VXI-Series amplifier through built in DSP, and a dedicated amplifier channel for each C7-Series loudspeaker in the system.  Precise setup of equalization, delay and crossover filters will ensure optimal in vehicle performance.

Design bandwidth:

• Through 48 and 24 and 12 dB / octave filters: 300 and 400 and 500 hz - 10 kHz
  
• Built through global components
  
• Sold individually, including a cast alloy and 1 fine mesh and spiral steel grille tray and insert
• The performance of every C7-Series driver is tested and verified, then assigned a unique serial number.  Register your C7-Series loudspeaker online to receive a copy of its specific acoustical test report.
