Diamond Audio 6.5" 2-Way High Output Marine Speaker (2Ω) - HXM65F2BK

Diamond Audio HXM65F2BK — 6.5" HXMFB Series 2-Way High Output Marine Coaxial Speaker (2Ω)

The Diamond Audio HXM65F2BK is the latest evolution of the legendary HXM and HXMF coaxial platforms, now reimagined as the HXMFB Black Series. Built for marine and motorsports applications that demand higher output, deeper bass response, and more extended high-frequency performance, the HXM65F2BK combines a carbon fiber cone, a neodymium motor structure, and an oversized 1.5" titanium dome tweeter into a waterproof, fiber-reinforced composite basket — delivering 150W RMS with 95dB sensitivity in a compact 2.52" mounting depth.

Available in both 2Ω and 4Ω configurations to optimize system design, the HXMFB series is engineered for Harley Davidson motorcycles, boats, UTVs, and custom marine builds where class-leading output and durability are non-negotiable.
