Overview

PRV Audio 8MR500CF-NDY-4 8" Midrange Neodymium Speaker Pair 4 Ohm

8MR500CF-NDY-4 8" Midrange Neodymium Speaker Pair 4 Ohm

The MR500CF-NDY series was engineered for powersports applications, featuring a water-resistant design that delivers reliable performance while withstanding the challenges of outdoor environments.

Perfect for enhancing your audio system on boats, UTVs, ATVs, or motorcycles, this midrange speaker sets a new benchmark for vocal clarity in outdoor use. Built with premium components including a carbon fiber cone, high-temperature voice coil, and a powerful neodymium magnet, it delivers natural sound with impressively low distortion.

  • Water resistant with authentic pro audio midrange performance 
  • Damped carbon fiber cone reduces moving mass and controls unwanted resonance 
  • Low inductance design with extended frequency response 
  • High-strength neodymium motor includes distortion-reducing components 
  • Quick transient response with minimal coloration and impactful midbass 
  • Sold in matched pairs with grille and mounting screws included

This midrange features a suspension system with a single-layer spider and premium stitched lead wires connected to a copper-clad aluminum voice coil, ensuring high efficiency and strong power handling. The voice coil is immersed in a powerful magnetic field generated by high-power neodymium radial slugs, optimizing performance. 

You can count on excellent off-axis dispersion and fast transient response, delivering a wide sound stage and realistic, detailed sound from this water-resistant driver.

Built for loud, clear vocal performance in tight and compact installations, PRV Audio’s 8MR500CF-NDY-4 neodymium midrange delivers 96 dB sensitivity (2.83V/1m) while weighing just 4.16 pounds. With a 4-ohm impedance, it's engineered specifically for high-output motorsports audio systems. 

Its bumped back plate, vented magnet structure, and vented pole piece work together with the high-temperature voice coil to enable strong power handling and durability. These features help the driver withstand intense transient power spikes, ensuring reliable performance in demanding conditions.
