JL Audio C6-275cm C6 series 2-3/4 inch Midrange Speaker

Dial in your mids

When you're goal is fully dialed-in 3-way car sound, this 2.75" driver delivers clean, articulate performance right where you need it most. Designed for custom systems and serious sound staging, the JL Audio C6-275cm midrange driver brings surgical clarity to the critical midrange zone — think vocals, guitar riffs, and snare hits with zero fluff. A fine mesh grille and screw-on, interchangeable mounting system with adapter rings make it a clean fit in a wide range of OEM dash locations, including GM, Toyota, Ram and many Euro makes.

Engineered for precision

Built with a mineral-filled polypropylene cone and a rubber surround, the C6-275cm delivers low distortion and high detail. JL used their advanced DMA (Dynamic Motor Analysis) tech to fine-tune the motor structure, so the speaker hits clean and hard when you crank it. It's like a high-performance engine running smoothly at redline — less distortion and more control, every time you open it up. A flat spider and EFC (Elevated Frame Cooling) keep things cool while allowing excellent excursion.

Clean design

At just over 1.42" deep, this driver is made to fit where others won't. It's ideal for A-pillars, dash pods, or anywhere a tight footprint and refined sound are both non-negotiable.

Includes fine mesh grille and adapter rings to fit a variety of OEM dash locations, including GM, Toyota, Ram and many Euro vehicles
