Diamond Audio 6.5" Midrange Speakers Motorsport High Output 4 Ohm MSPRO65
Diamond Audio products are designed, developed, and engineered using the latest innovative materials and components to provide the finest sound reproduction possible. These speakers use a pro audio design that gives you great levels of output. The MSPRO65 speakers have a very distinct low-frequency response. Pumping out at 400 watts max and an advanced voice coil heat sink design for better heat dissipation, you'll achieve crystal clear, concert-quality music you can hear at any speeds. These speakers were designed to work just as great in the saddlebags of motorcycles at top speeds.
