JL Audio C7-650CW 6.5 inch Woofer with Grille

The C7-650W woofer is capable of operating in a 3-way system, with midrange and tweeter, or with the tweeter alone in a 2-way configuration. Engineered from the ground up, it features exceptional linear excursion capability and outstanding linearity, which translates to solid bass and pure, precise midrange performance. Distortion and non-linearities have been minimized through optimization of the dynamic behaviors of the motors and suspensions.

Passive crossover networks are not included with C7 speakers, as they are designed for active systems. Instead, a high-quality tuning DSP is recommended, such as the JL Audio TwK 88 or D8, or a VXi amplifier with integrated DSP, with a dedicated amplification channel for each C7 system speaker. Precise adjustment of equalization, delay and crossover filters will ensure optimal performance within the vehicle.

Built in the USA. Sold individually, with an alloy grille tray, a fine mesh steel grille insert and a spiral steel grille insert. The performance of each C7 speaker is tested and verified, so a unique serial number is assigned. Register your C7 speaker online to receive a copy of the specific acoustic test report.

C7-650cw Features

  • Cone and Dust Cap: The polypropylene material, vacuum formed and mineral filled, offers excellent damping and reduced mass. The cone body features a gently curved profile to optimize response. A specially shaped dust cap connects to the cone body and the first voice coil to improve high frequency behavior.
  • Suspension Design: The moving assembly is suspended and damped by a large diameter spider, linear profile, formed from a blend of Nomex® and polycotton, and a positive rolling rubber surround. The two elements combine to provide optimal damping without prematurely limiting the exceptional excursion capability of the C7-650cw.
  • Motor Design: The C7-650CW employs a high density magnetic circuit with a high quality Y35 strontium ferrite magnet and a specially worked motor topology with T-yoke. Motor magnets have been precisely optimized using advanced FEA tools to reduce distortion and provide linear motor force across the driver's performance range.
  • An oversized 32 mm diameter voice coil is employed, wound with copper wire on a fiberglass former. The oversized voice coil provides greater power handling capability, minimizing thermal compression and distortion at higher listening levels. Frame Design: A specially designed cast alloy basket is used, with thin spokes to maximize rear open area and our patented Elevated Frame cooling technology.
