Diamond Audio 6"x9" 2-Way Coaxial Speaker w/Titanium Dome Tweeter (2Ω) - MS692CX2
Turn it up and let it roar—the Diamond Audio MS692CX2 6"x9" 2-way coaxial Coax-Sub speakers (2Ω) are built to deliver explosive output, deep bass, and crystal-clear highs in the toughest environments. Designed for marine audio, motorcycles, UTVs, and powersports systems, this 2-ohm version is engineered for maximum amplifier efficiency and louder, more aggressive performance. Simply put—this speaker bangs.
Built to IPx65 marine-grade standards, the MS692CX2 is ready for water, salt, sun, and dust. The UV-treated waterproof Kevlar cone with rubber surround delivers tight, punchy mid-bass and enhanced durability, making it perfect for open-air and high-vibration environments.
The standout feature is its Coax-Sub design, giving you extended low-frequency response without needing a dedicated subwoofer. With a frequency response of 46Hz–20kHz and 130W RMS / 500W MAX power handling, this 6x9 coaxial speaker produces rich, full-bodied sound that hits hard while staying clean and controlled.
Up top, the 1" high-output titanium dome tweeter delivers sharp, detailed highs that slice through wind and engine noise. The integrated 12dB Bessel crossover network ensures smooth transitions between frequencies, creating a balanced and dynamic listening experience.
The 2-ohm impedance allows your amplifier to push more power, resulting in higher output and improved system performance. Combined with a super high-energy ferrite motor system and milled aluminum top plate, the MS692CX2 delivers serious output with excellent control.
A T-yoke back plate design improves cooling by 35%, while the cast aluminum basket ensures long-term durability in harsh conditions.
The Diamond Audio MS692CX2 Coax-Sub speakers deliver aggressive, full-range sound with serious punch—built for riders and adventurers who want maximum volume, deep bass, and unstoppable performance on every ride.
