2.75-inch (70 mm) Component Midrange, with Grille
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.
