Diamond Audio 6"x9" 2-Way Coaxial Speaker w/Titanium Dome Tweeter (2Ω) - MS692CX2

Diamond Audio MS692CX2 — 6"x9" 2-Way Marine Coaxial Speaker with Titanium Dome Tweeter (2Ω)

The Diamond Audio MS692CX2 is the 2Ω variant of the MS69CX Coax-Sub platform, engineered for riders, boaters, and off-road enthusiasts running low-impedance amplifier systems who demand maximum output and full-range performance in harsh environments. Built to IPx65 marine-grade specifications, the MS692CX2 combines a UV-treated waterproof Kevlar cone, a 1" titanium dome tweeter, and Diamond Audio's "Coax-Sub" design to deliver deep bass extension, clear midrange, and crisp highs — all from a single speaker.

With a frequency response of 45Hz–23kHz and 130W RMS / 520W MAX power handling, the 2Ω impedance allows your amplifier to push more power for higher output and more aggressive performance. A 12dB Bessel crossover network ensures smooth frequency transitions, while the T-yoke back plate motor design improves cooling by 35% for sustained high-power reliability.
