Diamond Audio HXM65F4BK 6.5" HXMF Black Series 2-Way High-Output Marine Speakers w/ Carbon Cone (4Ω) (Pair)

The Diamond Audio HXM65F4BK is a 6.5" HXMF Black Series high-output marine speaker — a rigid carbon-fiber cone and oversized titanium dome tweeter on a neodymium motor, sold as a matched pair. The top of Diamond's marine line, fully waterproof and built for boats, baggers, side-by-sides, ATVs, and slingshots.

Why we recommend them

The Black Series is Diamond's highest-output marine speaker. A stiff carbon-fiber cone stays composed at high volume for clean, distortion-free output, an oversized titanium dome tweeter throws cutting highs over wind and engine noise, and a neodymium motor keeps it efficient. Unlike water-resistant speakers, the Black Series is fully waterproof and salt- and UV-resistant, so it lives outdoors without worry. The fiber-reinforced composite basket adds strength and corrosion resistance. The 4-ohm build is easy to drive from most amplifiers.
