With the very first note, Focal’s Access Series 165AC 6-1/2″ speakers will make your old factory models a distant memory. Featuring high-quality components in the built-in crossover, these speakers ensure a seamless distribution of frequencies to the woofer and tweeter, resulting in a completely natural sound. The DFS (dual fiberglass structure) woofer cone delivers precise mid-bass and midrange reproduction, offering rich, articulate bass. Enhanced by a butyl rubber surround, the cone’s all-weather durability guarantees exceptional performance, even in the most extreme heat and humidity, without any distortion or warping.
