Diamond Audio MP525 — 5.25" 2-Way Full-Range Coaxial Speaker with 1" Horn Tweeter (4Ω)

The Diamond Audio MP525 is a 5.25" 2-way coaxial speaker engineered for riders, boaters, and adventurers who need high-output, high-clarity audio in demanding environments.

Designed for Harley Davidson motorcycles, boats, and recreational vehicles, the MP525's compact 2.99" mounting depth and 4.68" mounting diameter make it easy to fit in tight spaces including motorcycle fairings and marine enclosures. Water-resistant construction ensures durability in high-vibration, high-exposure environments.
