Diamond Audio HXM65FBK 6.5" High-Output Horn Coaxial Speakers — 2Ω or 4Ω
The Diamond Audio HXM65FBK Black Series 6.5-inch horn-loaded coaxial speakers are built for high-output motorcycle, marine, and powersports audio systems where strong projection, clean midrange, and crisp high-frequency output are required.
Available in both 2-ohm and 4-ohm versions, the HXM65FBK combines a rigid carbon-fiber cone, oversized 1.5-inch titanium tweeter, lightweight neodymium motor structure, and fiberglass-reinforced composite basket for serious open-air performance.
6.5" High Output Built for Open-Air Audio
Designed for motorcycles, marine systems, and powersports applications where output, projection, durability, and efficient amplifier use matter.

High-Output 6.5" Horn Coaxial Design
The HXM65FBK combines a 6.5-inch carbon-fiber midrange cone with an oversized titanium high-frequency driver in a horn-loaded coaxial configuration. This architecture is designed to produce the projection and efficiency needed in motorcycle and other open-air audio environments.
Rather than relying on a conventional automotive coaxial design, the HXM Black Series is engineered around higher acoustic output and far-field performance where wind, road, engine, and exhaust noise compete with the audio system.
Carbon-Fiber Cone for Stronger Output
Diamond Audio uses a rigid carbon-fiber cone to combine low moving mass with high structural stiffness. The result is a cone designed to maintain control at elevated playback levels while improving impact and projection from a compact 6.5-inch platform.
Oversized 1.5-Inch Titanium Tweeter
The HXM65FBK uses Diamond Audio's larger 1.5-inch titanium tweeter to increase high-frequency output and improve projection in open-air installations.
The combination of the horn-loaded architecture and titanium diaphragm helps the speaker maintain high-frequency presence at speed instead of allowing the top end to disappear beneath road and wind noise.
150W RMS Power Handling
Diamond Audio rates the current HXM65FBK Black Series at 150 watts RMS and 450 watts maximum power per speaker. Both 2-ohm and 4-ohm versions are available so the speaker impedance can be matched correctly to the amplifier and complete system design.
2Ω — HXM65F2BK
The 2-ohm model allows compatible amplifiers to produce increased channel output and can be useful in systems designed around lower-impedance speaker loads.
4Ω — HXM65F4BK
The 4-ohm version offers additional flexibility for multi-speaker wiring, amplifier channel loading, and systems designed around higher-impedance configurations.
Neodymium Motor and High-Excursion Suspension
A lightweight neodymium motor structure helps reduce physical size and weight while maintaining the magnetic strength required for high-output operation.
Diamond Audio lists 2.75 mm of Xmax for the current HXM65FBK platform, supporting controlled cone movement and improved midbass capability from the 6.5-inch driver.
Built for Motorcycle, Marine and Powersports Use
The HXM Black Series is designed around marine and motorsports applications where the speaker may be exposed to moisture, heat, vibration, and UV.
- Carbon-fiber cone construction.
- Fiberglass-reinforced polymer composite basket.
- Rubber surround.
- Lightweight neodymium motor structure.
- Titanium high-frequency diaphragm.
- Designed for marine, motorcycle, motorsports, and powersports applications.
Motorcycle Audio Applications
The HXM65FBK is well suited to custom Harley-Davidson, Indian, Slingshot, powersports, and marine systems that require a high-output 6.5-inch coaxial speaker.
Applications may include fairings, lower pods, tour packs, custom saddlebag locations, fabricated speaker panels, marine installations, and other positions designed to accept a 6.5-inch speaker.
Installation and Tuning Notes
- Select the 2Ω or 4Ω version based on the amplifier and complete system layout.
- Verify amplifier RMS output at the selected impedance.
- Confirm the 5.44-inch mounting cutout before modifying factory or aftermarket panels.
- Verify the full 2.52-inch mounting depth and rear motor clearance.
- Confirm grille and fairing clearance before final assembly.
- Use appropriate high-pass crossover protection for the installed power level and application.
- Secure mounting hardware appropriately for motorcycle vibration.
- Protect wiring and terminals from moisture, abrasion, heat, and moving components.
- Complete final EQ and crossover tuning after the complete audio system is installed.

Need Help Choosing 2Ω or 4Ω?
The correct impedance depends on amplifier output, channel configuration, number of speakers, wiring method, and the complete system design. Garage Bagger Stereo can help determine the correct version before you order.
