Features

The 8MR450CF-4 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 midrange 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.

  • Water Resistant with true PRO audio midrange performance
  • Damped carbon fiber cone lowers moving mass and minimizes unwanted resonances
  • Handles 450 Watts – Endurance at Loudest Volumes
  • 4 Ohm Impedance
  • Also available in 6.5″ – 6MR400CF-4

The tailored response of the 8MR450CF-4 comes from its exotic yet supremely engineered carbon fiber cone that delivers the signature PRV audio combination of depth and accuracy on vocal reproduction.

Beyond good looks, this cone is extremely light, surprisingly rigid, and provides excellent damping to keep narrow peaks under control, resulting in an incredibly natural yet accurate sound.

PRV 8″ Carbon Fiber Speaker 8MR450CF-4 Midrange 450 Watts / 4 Ohm Water Resistant Loudspeaker

Recommended Amplifier configurations and crossover points:

2 Speakers – 1x MDX1200.2 1 Ohm, Bridged both speakers in parallel
4 Speakers – 1x MDX1800.1 1 Ohm, 4 speakers in parallel

Recommended HPF using PRV Digital Signal Processor DSP when using up to 450 Watts RMS musical power

  • 125 Hz at 12 dB per octave filter Crossover / BT12
  • 115 Hz at 18 dB per octave filter Crossover / BT18

If you have a super tweeter on your system the recommended LPF is 8,000 at 18 dB per octave filter Crossover / LR18 but you may set it lower to blend in better depending on the other components in your system, or you may not use a LPF at low power to take advantage of its high frequency response.

Technical Details

GENERAL SPECIFICATIONS

*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 provide 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.
