Hertz Mille Pro MPX 165.3 is a 6.5-inch Mille Pro coaxial speaker pair built for high-performance car audio upgrades where a coaxial speaker needs strong output and refined sound quality.
The MPX 165.3 uses a concentric tweeter layout to create a more coherent emission point than many standard coaxials, making it a strong option for premium door, rear, or custom speaker locations.
