Hertz Mille Legend ML 1800.3 - 6.5 Inch Midwoofer for Precise Mid-Bass
The Hertz Mille Legend ML 1800.3 is a 6.5-inch midwoofer for ambitious front systems. It combines the known precision of the ML 1650.3 with more depth and higher control. The 50mm dual voice coil provides high thermal reserves, and the "Boundary Free Surround" increases the effective cone area for more sound pressure. Ideal if you are looking for a tight, controlled kick bass in the door with a clean transition to the mid-range. Available at Carhifi.shop.
