Diamond Audio 6.5" Horn Coaxial Speaker 300W Max MP654

The Diamond Audio MP654 is a 6.5" 2-way full-range coaxial speaker built around a horn-loaded 1" compression tweeter, engineered for motorcycles, boats, and other powersports vehicles. A neodymium-powered mid driver with a 1.5" high-temp voice coil handles the low end, while the horn tweeter throws focused highs that stay clear at speed. Sensitivity runs 92.7 dB on the midbass and 107dB on the tweeter, with a frequency response of 110Hz-18kHz. Power handling is rated at 150W RMS and 300W max at 4 ohms, tuned with a 12dB second-order crossover. The tweeter diaphragm is field replaceable.

Construction includes a heavy duty steel basket and neodymium motor for a compact mounting footprint ( 5.73" mounting diameter, 3.33" mounting depth). The MP654 is water resistant, built for open-air riding and boating, though not intended for submersion.
