The MR500CF-NDY series was designed for Power sports applications, featuring a water-resistant design to ensure optimum performance taking into account the effects of the outdoor environment!

Ideal for upgrading your sound system in your boat, UTV, 4-wheeler, or motorcycle, this mid range speaker becomes the new standard in vocal reproduction for outdoor applications. Constructed of high-end materials like a carbon fiber cone, high-temperature voice coil, and huge neodymium magnet, this driver produces natural sound with remarkably low distortion.

8MR500CF-NDY-4 Highlights


  • Water Resistant with true PRO audio midrange performance
  • Damped carbon fiber cone lowers moving mass and minimizes unwanted resonances
  • Low inductance and extended frequency response
  • Powerful neodymium magnet structure features distortion-canceling fixtures
  • Fast transient response, minimal tonal coloration, and deep, dynamic midbass
  • Sold in pairs – Grill and screws are included
  • Also available on 6″ – 6MR500CF-NDY-4

8MR500CF-NDY-4 Terminal

The suspension design of this midrange features the single layer spider – which connects to the coil former with premium stitched lead wires, all being driven by a copper-clad aluminum wire voice coil providing high efficiency and excellent power handling, complemented by a high-power neodymium radial slugs that immerse the voice coil in a strong magnetic field.

You can expect excellent off-axis and transient response from this water-resistant mid range for a great sound stage and realistic sound reproduction.

8MR500CF-NDY-4 Magnet

Built for loud, clear vocal performance in tight, compact spaces, PRV Audio’s 8MR500CF-NDY-4 neodymium-powered midrange features a sensitivity of 96 dB (2.83V/1m) and weighs about 4.16 pounds! 4 ohm impedance. Pro Audio On Wheels Series is dedicated to delivering outstanding pro audio performance to your motorsports application.

A bumped back plate, vented magnet system, vented pole piece, high-temperature voice coil, allow for high power handling while protecting this driver from extreme transient power peaks.

Haven’t had the chance to ride it yet as it turned cold and snowy here now. It after some adjustments on the amp and EQ they sound great hopefully they hold up as well as I expect.

Great product

Installed on my roadking and they are what I was looking for

Tijuana Glenn-Brown

Johnny Brooks Jr

Love the speakers

Amazing sound quality

I went with these for the water resistance. After a long resurch I decided to use all PRV speakers for my harley build. I have the 8", 6.5" and the bullet horn tweeters. Paired with the dsr1 and 2 amps the sound quality is amazing. If your building a bike and want to be heard and have amazing quality these are a must buy!!
