MP Speakers - Frequently Asked Questions

Q1: What are Diamond Audio MP Series speakers designed for?
A: They are designed for high-output audio on Harley Davidson® motorcycles, boats, UTVs, and recreational vehicles — applications where efficiency and loudness matter most.

Q2: What makes the MP Series so loud and efficient?
A: Each model is a 2-way full-range coaxial design with a 1" horn style tweeter. The horn projects sound farther and delivers high-decibel output while drawing minimal power from your amplifier.

Q3: Which size and impedance should I choose?
A: The series covers 6.5" (MP654 4Ω, MP652 2Ω), 6"x9" (MP694 4Ω, MP692 2Ω), and 8" (MP84 4Ω). Match the impedance to your amplifier — 2Ω models pull more power from the same amp, while 4Ω models suit standard multi-channel setups.

Q4: Are they waterproof?
A: They are water resistant, not waterproof. They handle rain and spray on the road or the water, but large amounts of water can damage them.

Q5: What happens if the tweeter wears out?
A: Every MP Series speaker uses a replaceable tweeter diaphragm. The MPRD replacement diaphragm fits MP652, MP654, MP692, MP694, MP82, MP84, and MP525, so you can restore high-frequency performance without replacing the entire speaker.

Q6: Why choose MP Series speakers?
A: They combine horn-loaded efficiency, a high-end cast basket, serviceable tweeter diaphragms, and Diamond Audio sound quality built to survive marine, motorcycle, and powersports environments.
