The product is a pair of JL Audio CF-350MT Custom Fit 3.5" Mid-Tweeters Coaxial speakers, which are brand new and sealed. These speakers are designed to provide high-quality audio performance, particularly in the mid and high-frequency ranges. They are custom fit, indicating a specific design for a certain make and model of vehicle or audio system. The use of the term "Coaxial" suggests that these speakers have both a mid-range driver and a tweeter housed within the same unit, allowing for a more compact design while still delivering clear and detailed sound reproduction.
