1 Pair- Diamond Audio MP654 6.5" Pro Full-Range Co-Axial Horn Speakers

The new Diamond Audio MP654 speakers are a perfect solution for 2014 and later Harley baggers. These speakers are an easy fit and do not require an additional tweeter location on the fairing. They simply bolt into the factory speaker locations ( Fits '14 & up batwing fairings (Street Glide, Electra Glide, Ultra). Fits '15 & up Road Glide with slight modification to fairing speaker pods (heat gun is used to make a little more room for the magnet, or with use of adapter plates if applicable ). Fits '13 and down batwing fairings if you grind off the small plastic rib on the inside of the outer fairing. Does not fit '13 and down Road Glide, tour pack location on Ultra models, or lower fairings without custom fabrication. It is the buyers responsibility to measure for fitment prior to ordering. )

Serial Numbers Are Recorded and Photographed Per Each Customer Order. Any product returned for any reason Must be returned in its original and serial number matching box / packaging.

These speakers are louder, play lower, with more authority and sound better right out of the box than other pro audio speakers for Harley applications. With an over sized voice coil, extreme sensitivity for unreal output, high heat dissipation neodymium magnets and mounting dimensions specific to late model Harley fairings, these speakers are at the very top of the food chain. Don'tsettle for less, these are built to play loud and clear while cruising.
