JL Audio C7650CW 6.5" 3-Way Component C7 Car Woofer (Single)

THE ULTIMATE IN AUTOMOTIVE AUDIO FIDELITY

Built from the ground up to exceed the highest standards, JL Audio C7 speakers make no compromises in delivering a pure and precise audio experience.

Part Number: 010-03126-00

Key Features

• Component drivers for active systems
• Driver-specific crossover settings provided for two- or three-way systems
• Sold individually for flexible system design
• Available in 3 sizes: 6.5-inch woofer; 3.5-inch midrange; and 1-inch tweeter

Features

• ELEVATED FRAME COOLING The patented Elevated Frame Cooling design by JL Audio delivers cool air through slots directly above the top plate to the voice coil of the speaker. This enhances power handling as well as sound quality by minimizing dynamic parameter shifts and power compression.
• GRILLE OPTIONS C7-650cw and C7-350cm speakers each include a cast-alloy grille tray, one fine mesh steel grille insert and one spiral steel grille insert.
• ALUMINUM DOME TWEETER Lightweight aluminum dome tweeters deliver sparkling high-frequency detail that extends well beyond the frequency response of typical human hearing.
• FINITE ELEMENT ANALYSIS (FEA) MOLDED DRIVERS C7 design solutions were created and refined by using powerful mechanical and FEA modeling systems from JL Audio, including their proprietary dynamic motor analysis software. These studies led to innovative motor and suspension solutions, which were key to meeting the C7 design goals for smooth off-axis response, dynamic stability and low distortion.
• DESIGNED FOR ACTIVE CROSSOVERS A high-quality DSP — such as the JL Audio TwK® 88, TwK D8 or a VXi amplifier with built-in DSP — is recommended, with individual amplifier channels for each C7. With this approach, the system designer can use delay, crossover parameters and precise equalization to adjust for speaker placement, cabin acoustics and target response.
