Diamond Audio HXM57F2BK 5"x7" HXMF Black Series 2-Way High-Output Marine Speakers w/ Carbon Cone (2Ω) (Pair)

The Diamond Audio HXM57F2BK is a 5x7" HXMF Black Series high-output speaker — a carbon-fiber cone and 1.25" titanium tweeter on a neodymium motor, and a true Harley direct-replacement fitment. Sold as a matched pair, fully waterproof and ready for baggers, boats, side-by-sides, ATVs, and slingshots.

Why we recommend them

The 5x7 Black Series drops straight into Harley 5x7 speaker locations — no adapters, no cutting — while delivering Diamond's highest-output marine sound. A stiff carbon-fiber cone stays composed at volume, a 1.25" titanium tweeter throws cutting highs over wind and engine noise, and a neodymium motor keeps it efficient. Fully waterproof and salt- and UV-resistant, with a fiber-reinforced composite basket. The 2-ohm build lets you pull more power from your amp.

Fitment & install notes
