About: JL Audio C6-275cm 2.75-inch Component Midrange Speaker (Each)

Sharing key technologies used in our flagship C7 series, the C6-275cm midrange speaker is engineered to deliver crisp, clear performance and high-frequency extension in a variety of existing OEM interior configurations.



Benefiting from JL Audio expertise in motor, suspension and cone modeling systems, the C6 series speakers are designed to play loudly while maintaining smooth, dynamic low-distortion sounds. At the core of C6-275cm is a proprietary DMA-optimized motor system. A flat, linear profile spider promotes linear compliance, while a robust voice coil assembly supports extended power-handling capability and serves to limit thermal compression and distortion at higher volume levels. Each speaker’s frame is outfitted with a screw-on, interchangeable mounting system, including adapter rings to easily fit behind OEM factory trim in dashboard locations.

C6-275cm Component Midrange Features:

• Forged and machined motor plates with DMA-optimized geometries create linear motor force under power, leading to outstanding midrange reproduction, linearity and low distortion
• A flat, linear profile spider promotes linear compliance and outstanding excursion capability
• Robust voice coil construction, forced cooling and optimized moving assembly components maintain low power compression at higher listening levels
• Includes fine mesh grille and adapter rings to fit a variety of OEM dash locations, including GM, Toyota, Ram and many Euro vehicles
