At the core of the JL Audio CF-275mt mid-tweeter is a proprietary, 2.75" (70 mm) composite frame and a DMA-optimised motor system. An ultralight, fiber-reinforced pulp cone with a custom "S" roll surround delivers excellent efficiency and extended high-frequency response.
A flat, progressive-roll spider ensures linear compliance, while the neodymium motor packs astonishing energy from an ultracompact and lightweight package. Each speaker's glass-filled, high-temperature polymer frame is outfitted with insert-molded terminals and a low-profile perforated metal grille to easily fit behind factory trim while providing excellent UV protection in exposed dashboard locations.

For passive applications as midtreble speakers, in-line second order high-pass filters are included to enhance smoothness and improve power handling. CF-350mt speakers can also be used actively as true midrange or mid-tweeter drivers to create outstanding two-way or three-way systems.
For active applications, JL Audio recommend a high-quality digital signal processor (DSP), such as the JL Audio TwK® DSP or a VXi amplifier with built-in DSP, and the recommended bandwidths below.
