Diamond Audio 6"x9" 2-Way Coaxial Speakers w/Titanium Dome Tweeter (4Ω) - MS69CX

6"x9" 2-Way Coaxial Speakers w/Titanium Dome Tweeter

Meet the speaker that refuses to stay in one lane. The Diamond Audio MS69CX 6"x9" 2-way coaxial Coax-Sub speakers blend midrange clarity, crisp highs, and surprising low-end authority into one rugged, marine-ready package. Designed for boats, ATVs, UTVs, motorcycles, and outdoor audio systems, these speakers deliver powerful, full-range performance in environments where ordinary speakers tap out.

Engineered to IPx65 marine-grade specifications, the MS69CX is built to withstand water, salt, UV exposure, and extreme conditions. The UV-treated waterproof Kevlar cone with rubber surround ensures durability and tight, responsive bass, while maintaining excellent midrange accuracy for vocals and instruments.

At the top end, a 1" high-output titanium dome tweeter delivers crisp, detailed highs that cut through wind and ambient noise with precision. The integrated 12dB Bessel crossover network ensures smooth frequency transition, creating a balanced and natural soundstage across the full spectrum.

What sets the MS69CX apart is its “Coax-Sub” design, combining the output of a coaxial speaker with enhanced low-frequency capability. With a frequency response of 46Hz–20kHz and 125W RMS / 500W MAX power handling, these 6x9 marine speakers provide rich bass extension without the need for a dedicated subwoofer in many applications.

The super high-energy ferrite motor system and milled aluminum top plate enhance efficiency and control, while the T-yoke back plate design improves cooling by 35%, allowing for higher power handling and long-term reliability. A cast aluminum basket adds strength and vibration resistance for demanding environments.
