Diamond Audio MP84 8" PRO Full-Range Co-Ax Horn Speakers (Pair)

The Diamond Audio MP84 is an 8" full-range co-ax horn loudspeaker with a rear-mounted, full-sized compression driver — seriously loud pro-audio sound from a single speaker, built for baggers, boats, slingshots, and powersports.

Why we recommend them

The MP84 goes big. A full-sized compression driver mounted behind the 8" cone delivers horn-loaded highs with real authority, and the neodymium ring magnet assembly keeps it efficient at a strong 103dB sensitivity. With a 1.75" voice coil and a wide 80Hz–18kHz range, it plays low and loud enough to carry a front stage on its own — no separate tweeter needed.

Fitment & install notes

Sold as a pair. 12dB crossover protects the compression driver. Pair with a pro-audio amp to feed the big motor. Confirm you have the depth for an 8" pro speaker before mounting.
