Overview

PRV Audio MT6MR400CF-NDY-4 SLIM Moto Series 6.5" Carbon Fiber Neodymium Midrange Loudspeaker 4 Ohm

PRV Audio proudly introduces the MOTO Series (MT), a high-performance PRO audio line developed specifically for motorsports installations. This series incorporates advanced materials and components designed to withstand harsh weather while delivering top-tier sound reproduction. 

This midrange loudspeaker sets a new benchmark for vocal clarity in outdoor use, making it a top choice for upgrading the audio system in boats, UTVs, 4-wheelers, Slingshots, or motorcycles. 

With premium components like a carbon fiber cone, high-temperature voice coil, and robust neodymium magnet motor, it delivers natural sound with impressively low distortion.

  • Water-resistant speaker delivering an authentic pro audio midrange performance
  • Carbon fiber cone with coated suspension designed for outdoor durability
  • Full-range sound with low inductance technology, extending frequency response up to 12,000 Hz
  • High-output speaker ideal for ATVs, Slingshots, and motorcycles, fitting most stock mounting locations
  • Engineered for compact spaces with a slim 2.22" mounting depth, without compromising quality or performance
  • Grille and screws are included

In addition to its sleek appearance, this carbon fiber cone is remarkably lightweight, highly rigid, and offers excellent damping to manage narrow peaks.

Despite its compact design, PRV's technical team achieved precise vocal reproduction, delivering the renowned PRV Audio pro sound.

A specially treated surround and flat spider support the cone, maintaining linear movement through its full excursion with minimal restriction, enhancing dynamics and transients.

This midrange includes several premium components, such as stitched lead wires that connect the voice coil to the terminals through a single-layer spider suspension. It’s powered by a copper-clad aluminum voice coil for high efficiency and outstanding power handling, combined with a robust neodymium motor that immerses the voice coil in a powerful magnetic field.

This water-resistant speaker delivers excellent off-axis and transient response, ensuring controlled sound and a smooth transition to a super tweeter.

Designed for loud and clear vocal performance in tight spaces, PRV Audio’s MT6MR400CF-NDY-4 SLIM midrange boasts a sensitivity of 95 dB (2.00V/1m) and weighs just 1.63 pounds, with a 4-ohm impedance.

The MOTO Series is crafted to provide exceptional pro audio performance for motorsports applications.

This speaker is engineered for reliable, consistent high output across a broad frequency range of 120 to 12,000 Hz, potentially eliminating the need for a super tweeter in your system.

    •  *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.
