The Lanzar OPTI6MI is a single 6.5-inch car midbass/midrange driver rated 250W RMS and 500W peak, built around a die-cast aluminum frame, a 30 oz magnet and a 1.5-inch high-temperature voice coil. Its 94 dB sensitivity means it plays loud on modest amplifier power, and the 105 Hz–12 kHz response covers midbass and vocals but not deep bass. Mounting depth is 3.03 inches, so check door or kick-panel clearance before buying. At $42.99 at Walmart as of November 4, 2026, it sits at the low end of its recent range among the 7 stores listing it new.
