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.

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.

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.

Note:   

• Nominal power handling is defined as the maximum RMS power that the speaker can handle in a 2-hour test with a pink noise with 6dB of crest factor and a bandpass filter with 12db/oct tuned in its usable frequency range.
• Continuous Program Power (RMS) is the maximum power that the speaker can handle considering a regular musical program using our recommended filters, this power can be used to define the optimum amplifier power to avoid a clean signal without clipping or saturation.
• Max Peak Power is the maximum power operation for the speaker, this power is allowed just for a few fractions of a second, usually found just on the peaks of the music. Keeping this power for a little longer timer will damage the speaker.
