The 8MR500-NDY v2 series was designed from the ground-up to become the new standard in vocal reproduction in compact enclosures. The new and improved version 2 meets the demand for an extreme lightweight and powerful midrange loudspeaker. Great addition to the MR Series! Built for loud and clear vocal performance in tight, compact spaces. The new Version 2 has improved its motor and basket design. Now featuring a new copper-clad aluminum voice coil for low moving mass to increase efficiency.
