Product Description

Features & Specifications



JL Audio C7-650cw 6.5″ Component Midwoofer Car Speaker – #99757

The C7-650cw component woofer is capable of operating in a 3-way system, with a midrange and tweeter, or with only a tweeter in a 2-way configuration. Engineered from the ground up, it has exceptional linear excursion capability and outstanding linearity, resulting in solid mid-bass and pure, precise, mid-range performance. Distortion and non-linearities have been minimized through critical optimization of dynamic motor and suspension behaviors.

Passive crossover networks are not included with C7-650cw 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, or a VXi amplifier with built-in DSP, with a dedicated amplifier channel for each C7-650cw loudspeaker in the system. Precise setup of equalization, delay and crossover filters will ensure optimal in-vehicle performance.

JL Audio’s flagship car speaker series

Whoa... That’s about all I could muster after demoing JL Audio’s C7-650cw component system at their headquarters. I was floored. Track to track, moment to moment, I was astounded by the clarity and presence reproduced by these speakers. Impactful loudness, rich detail, imaging that seemed almost magical — all of it facilitated an emotional connection that rivaled live performance.

Note: The C7 Series 6-1/2″ woofer, 3-1/2″ midrange, and 1″ tweeter are all sold singly.

Dream woofer

This C7-650cw 6-1/2″ woofer will bring satisfying midbass to your dream system. It’ll endure heavy use and extreme temperatures thanks, in part, to its mineral-filled polypropylene cone and a durable rubber surround. Its advanced dust cap sets this speaker apart from others in its class by extending its frequency response and allowing the driver to work gracefully in a 2- or 3-way system — and always sound phenomenal. A one-of-a-kind machined motor and oversized voice coil ensure minimal distortion under any appropriate power scenario. JL Audio also includes a handsome grille for a totally unique custom installation.

Make it part of an active system

The ultra-premium C7 Series has been years in the making, but its unveiling was contingent on JL Audio providing the ultimate tuning solution for optimal speaker performance — and that’s TüN, their latest audio-tuning software. Each C7-650cw speaker is sold à la carte to give you the freedom to design whatever system your ears desire. You’ll need an active crossover to use C7 speakers —  JL Audio’ recommends using their TwK™ 88 digital signal processor, which gives you access to the awesome sound-shaping power that TüN offers. The JL Audio engineers designed the C7-650cw to be neutral, without coloration, so that you can use TüN to craft exactly the right sound for you and your vehicle.

C7-650cw 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 specially shaped dust cap attaches to the cone body and the voice coil former to improve high frequency behavior.
  • Suspension design: The moving assembly is suspended and damped via a large-diameter, 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 C7-650cw’s outstanding excursion capability.
  • Motor Design: The C7-650cw employs a high-density magnetic circuit with a high-grade Y35 Strontium-ferrite magnet, and a specially machined, T-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 32 mm (1.27 inch) diameter, overhung voice coil is employed, wound with copper 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: A purpose-engineered cast alloy basket is employed, featuring thin spokes to maximize rear open area, and our Patented Elevated Frame Cooling technology.
