Overview

PRV Audio MT6CX580-NDY-4 Moto Series 6.5" Coaxial Loudspeaker

PRV Audio proudly presents the MT6CX580-NDY-4 Coaxial Speaker, part of our MOTO Series (MT), a high-performance PRO audio line built for motorsports installations.

This coaxial speaker installs easily and requires no additional tweeter. Built from premium materials and components, it withstands weather conditions and allows for a straightforward bolt-on upgrade that significantly improves sound quality over factory speakers. 

This 2-way coaxial loudspeaker sets a new standard for vocal reproduction in outdoor settings, making it an excellent choice for upgrading the audio system in boats, UTVs, 4-wheelers, Slingshots, or motorcycles.

  • Waterproof treated paper cone and surround ensure durability in harsh environments while delivering true PRO audio performance
  • Full-range sound with a 2-way coaxial design, combining a low-frequency speaker with a 1″ titanium driver, capable of responding from 100 Hz to 20,000 Hz
  • High-output speaker for ATVs, Slingshots, and motorcycles, easily fitting into most stock mounting locations
  • Shared neodymium motor design for both low and high frequencies, minimizing phase issues and offering a compact profile without compromising performance
  • 6.5″ high-performance coaxial speaker engineered for high output, featuring separate midbass and horn drivers for dual amplifier setups.

This coaxial speaker includes a built-in horn driver with a D280Ti titanium diaphragm, mounted on a 70° conical wide-coverage horn waveguide.

The horn's screw-on design allows for easy servicing, and it's constructed from durable PM-4 polycarbonate, a high wear-resistant material for long-lasting thread durability.

Capable of reproducing high frequencies with ease, it perfectly complements the low-frequency speaker for seamless phasing across a broad range.

This low-frequency speaker keeps pace with its high-frequency drivers due to its large voice coil, extreme 95dB sensitivity, and powerful neodymium magnets for efficient heat dissipation.

With an output of up to 130 dB, it pairs effortlessly with its high-efficiency horn tweeter for a balanced performance.

The specially designed spider prevents distortion at high excursion, while the silver tinsel lead wire handles high current, ensuring exceptional reliability and dynamic sound quality.


This 6.5″ coaxial horn speaker delivers exceptional high-output performance with a separate midbass driver and horn tweeter, allowing use with two amplifiers for optimal sound distribution. 

The midbass speaker is tuned for rich, deep low-frequency reproduction, while the horn driver handles crisp highs, ensuring each frequency band performs efficiently and without distortion. This separation produces a dynamic, balanced sound ideal for demanding setups. 

With its remarkable output levels, this coaxial stands out as one of the loudest speakers in its class—built to impress in compact installations that demand full-range power.

How to Install them: 

This Coaxial speaker will need 500 Watts RMS per speaker for its low frequency and 80 Watts RMS per driver for its high frequency with recommended HPF using PRV Digital Signal Processor DSP

  • 95 Hz at 18 dB per octave filter Crossover / BT18 for low frequency component 
  • 1400 Hz at 18 dB per octave filter Crossover / BT18 for high frequency component 

Recommended LPF for speaker is 6,000 Hz at 18 dB per octave filter Crossover / BT18 or you may set it lower to 2000hz depending on the other components in your system.

One Amplifier
2 Speakers Setup – 1x MDX2000.2 at 2 Ohm, 2 speakers in parallel into CH1 and 2 Drivers in parallel into CH2

One Amplifier
4 Speakers Setup – 1x MDX2000.4 2 Ohm, 2 speakers in parallel per CH1 and CH2 / 2 Drivers in parallel per CH3 and CH4

Reach the highest output level by following these installation recommendations for your coaxial with two amplifiers application!

Two Amplifiers 4 Speakers Setup
Speaker Amp 1x MDX2000.2 2 Ohm 2 speakers in parallel on each channel, giving each speaker up to 500 Watts each 
Driver Amp 1x QS400.4 2 Ohm 2 drivers in parallel per bridged channel, giving each driver up to 100 Watts each

*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.
