Features
The 6MR400CF-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 strong magnet motor, this speaker produces natural sound with remarkably low distortion midbass.

- Water Resistant with true PRO audio midrange performance
- Damped carbon fiber cone lowers moving mass and minimizes unwanted resonances
- Handles 400 Watts – Endurance at Loudest Volumes
- 4 Ohm Impedance
- Also available in 8″ – 8MR450CF-4

The tailored response of the 6MR400CF-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 6.5″ Carbon Fiber Speaker 6MR400CF-4 Midrange 400 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 400 Watts RMS musical power
- 145 Hz at 12 dB per octave filter Crossover / BT12
- 135 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.

Q & A
6MR400CF-4










Speaker sound great, can’t wait to get them on an amplifier.
I’m very impressed with the sound and quality of these speakers, I’m glad I waited until they had them in stock. Waited for them but it was worth it!! Thanks
Didn’t expect much from a midrange speaker, but this one punches above its weight. Carbon fiber cone really makes a difference and keeps it water resistant for my outside speakers, now my music sounds good inside and outside.
Super good speakers
💪🏽
Great speakers 👍🏻
21 Street Glide screaming at hwy speeds. They sound awesome. I’m very pleased at this point.
Simply amazing !!
These speakers are great. Sound loud and crisp And look awesome in carbon fiber. They hit all the notes just right. Couldn’t be any happy with my purchase. Would recommend these. I got them in a Chuchero box.
I received my speakers very fast and everything was A1
