Diamond Audio 6.5" MP Series 2-Way Full-Range Coaxial Speaker w/1" Horn Tweeter (2Ω) - MP652

Diamond Audio MP652 — 6.5" 2-Way Full-Range Coaxial Speaker with 1" Horn Tweeter (2Ω)

The Diamond Audio MP652 is the 2Ω variant of the MP Series 6.5" coaxial speaker, engineered for riders, boaters, and adventurers running low-impedance amplifier systems. Sharing the same proven MP Series platform as the MP654, the MP652 combines a high-temp NEO magnet motor, a 1" horn-style tweeter with a replaceable diaphragm, and a heavy-duty steel basket — delivering 250W RMS with 101dB sensitivity (1W/1M) for powerful, efficient output from motorcycle and marine amplifiers.

Designed for Harley Davidson motorcycles, boats, and recreational vehicles, the MP652's 3.33" mounting depth and 5.73" mounting diameter fit standard fairing and marine enclosure cutouts. Water-resistant construction ensures durability in high-vibration, high-exposure environments.
