  • C7 3.5" (90mm) High End Midrange Driver

Test result:

  • Test in Car & Hifi 4/2018 - Absolute top class - Score: 1.1 - Purchase value: very good - BEST PRODUCT.
Features:
  • 90 mm (3.5 inch) component midrange driver, with grille.
  • C7 is the pinnacle of JL Audio's car speaker design, benefiting from JL's most advanced engineering tools and full commitment to precision manufacturing.
  • The C7-350cm component midrange driver is designed to operate in a 3-way system with a woofer and tweeter. It has been designed and engineered from the ground up to provide exceptional transient response and outstanding linearity, resulting in unsurpassed midrange clarity and natural reproduction.
  • Distortion and non-linearity have been minimised by optimising the dynamic motor and suspension response.
  • Passive crossovers are not included with the C7 drivers as they are designed for active systems. Instead, JL recommends a high-quality tuning DSP, such as the JL Audio TwK™ 88 or D8, or a VXi amplifier with built-in DSP, with a dedicated amplifier channel for each C7 speaker in the system. Precise adjustment of equalization, delay and crossover filters ensures optimum in-car performance.
  • C7-350cm Construction Notes:
  • Cone and Dust Cap: Vacuum-formed, mineral-filled polypropylene material provides excellent damping and low mass. The cone body features a gently curved profile to optimize response. A concave dust cap further improves high frequency response.
  • Suspension Design: The moving assembly is suspended and damped via a linear profile spider formed from a Nomex®/poly-cotton blend and a positive roller rubber surround. Both combine to provide optimum damping without prematurely restricting deflection.
  • Motor Construction: The C7-350cm uses a high density magnetic circuit with a high quality neodymium magnet and a specially machined U-Yoke motor topology. The motor magnets have been precisely optimized using advanced FEA tools to reduce distortion and ensure linear motor force throughout the driver's power range.
  • A 1.42-inch (36 mm) diameter voice coil is used, wound with copper-clad aluminum wire on a fiberglass voice coil former. The oversized voice coil provides extended power handling and minimizes thermal compression and distortion at higher listening levels.
  • Chassis Construction: A specially designed cast alloy basket is used, featuring thin spokes to maximize rear open area.

Design Bandwidth:

  • With 48 dB/octave filters: 300 Hz - 10 kHz.
  • With 24 dB/octave filter: 400 Hz - 10 kHz
  • With 12 dB/octave filter: 500 Hz - 10 kHz
  • Built in the USA with global components
  • Available individually with a cast alloy grille insert, a fine mesh steel grille insert, and a spiral steel grille insert.
  • The performance of each C7 driver is tested and verified, then assigned a unique serial number. Register your C7 speaker online to receive a copy of its specific acoustic test report.
