Diamond Audio 6"x 9" MP Series 2-Way Full-Range Coaxial Speakers w/1" Horn Tweeter (4Ω) - MP694

Diamond Audio MP694 — 6"x9" 2-Way Full-Range Coaxial Speaker with 1" Horn Tweeter (4Ω)

The Diamond Audio MP694 is a 6"x9" 2-way coaxial speaker engineered for riders, boaters, and adventurers who need high-output, full-range audio in demanding environments. Part of the MP Series lineup, the MP694's larger oval format extends low-end response down to 80Hz while maintaining the same proven NEO magnet motor, 1" horn-style tweeter with replaceable diaphragm, and heavy-duty steel basket found across the MP Series — delivering 150W RMS with 101dB sensitivity (1W/1M).

Designed for Harley Davidson motorcycles, boats, and recreational vehicles, the MP694's 3.99" mounting depth and standard 6x9 cutout dimensions make it a direct upgrade for existing 6x9 locations in fairings, saddlebags, and marine enclosures. Water-resistant construction ensures durability in high-vibration, high-exposure environments.
