Refined sound meets everyday versatility with the Diamond Audio DES525 5.25" 2-way coaxial speakers, designed to deliver premium audio performance, clarity, and style in a compact, easy-to-install package. As part of the acclaimed Diamond Elite DES Series, these speakers are engineered for drivers who demand high-end sound quality in OEM and aftermarket upgrades.

At the heart of the DES525 is a composite carbon fiber cone, reinforced with a specially treated paper backing to deliver smooth, controlled mid-bass and accurate midrange response. This unique cone design ensures your music sounds balanced and natural, with excellent detail across a wide range of frequencies.

Complementing the midrange is a 25mm aluminum dome tweeter with ferrofluid cooling, engineered to produce crisp, detailed highs with excellent clarity and extension. The aluminum dome tweeter enhances high-frequency performance, allowing vocals and instruments to shine with precision while maintaining smooth, distortion-free output.

With 50W RMS / 100W MAX power handling, the DES525 offers reliable performance for both factory head units and amplified systems. Its 2.1-inch mounting depth and 4.62-inch cutout diameter make installation simple in a variety of vehicles, making it an ideal upgrade for doors, rear decks, or compact speaker locations.

The composite ABS frame provides durability and vibration resistance, ensuring long-term performance while maintaining a clean, modern look. Subtle yet refined styling enhances your vehicle’s interior without overpowering its design.
