PRV Audio is proud to present our MT6CX580-NDY-4 Coaxial Speaker from the MOTO Series (MT), high performance PRO audio line dedicated to motorsports installations.
This coaxial speaker is an easy fit and does not require an additional tweeter. Made from the highest quality materials and components to resist weather conditions and provide an easy and simple bolt on installation that transforms your system into the best sound reproduction available by replacing your factory speaker.
This 2-way coaxial loudspeaker established the new benchmark for vocal reproduction for outdoor applications, making it ideal for improving the sound system in your boat, UTV, 4 wheeler, Slingshot or Motorcycle.

- Waterproof treated paper cone and surround stand up to the harshest conditions with true PRO audio performance
- Full Range Sound, 2-Way coaxial with low frequency speaker combined with 1″ exit Titanium driver, able to respond from 100 Hz all the way up to 20,000 Hz
- High Output Speaker for 4 Wheelers, Slingshots, and Motorcycles that mounts practically in almost every stock location
- Common Neodymium motor design for both low frequency and high frequency, reducing phase problems and providing the smallest profile without sacrificing performance
- 6.5″ High performance coaxial speaker Built to Perform! Capable of high output levels, with separated midbass speaker and horn driver for two amplifier installation.

This coaxial features a built-in horn driver with D280Ti titanium diaphragm on a 70° conical wide coverage horn waveguide.
Its horn features a screw-on design to make it easy for the speaker to be serviced. Made from the toughest PM-4 Polycarbonate high wear-resistance material to ensure long life on its treads.
It is capable of reproducing the highest frequencies at easy covering a wide range, phasing up perfect with its low frequency speaker.

This low frequency speaker can keep up with its high frequency drivers thanks to its large voice coil and extreme sensitivity of 95dB, combined with large neodymium magnets for efficient heat dissipation.
It generates an average of 130 dB of output, making it easy to match up with its high efficiency horn tweeter.
Thanks to its special spider composition, no distortion occurs at high excursion, while its silver tinsel lead wire is capable of high current, providing exceptional reliability and dynamic sound.

This 6.5″ coaxial ( horn speaker ) is capable of high output levels and comes with a separate midbass speaker and horn driver for two amplifiers.
The separate midbass speaker is designed to handle lower frequencies, providing a rich and full bass sound, while the horn driver focuses on delivering clear and precise high frequencies. This division of labor allows each component to operate more efficiently, reducing distortion and ensuring a more balanced and dynamic overall sound quality.
Its incredible output capabilities make this coaxial one of the loudest speaker on the market!

Q & A
MT6CX580-NDY-4











I’ve used the MT6CX580-NDY-4 in a Road Glide and the results were insane.
Crystal-clear highs from the compression driver and strong mids even at highway speeds. Way louder and cleaner than a regular coaxial. If you want real performance in a compact setup, this is it. Check out my YouTube video showing exactly what this speaker is and how to use it!
Best sounding speakers I ever heard
I haven’t hook them up yet still ordering parts waiting on dsp now
I’ve tried different brands, groundzero and Hertz And This PRV Coaxials are the best I’ve tried!
Love these Speakers super clean and loud
They will fit with a little modification to the speaker pods, well worth it. Just dont expect too much bass out of them if you plan on putting the rated power to it. The woofers are connected to a soundigital 1200.2 and the horns to a soundigital 400.2
These speakers really impressed me hope they come out with a 8in. version. These were game changers for me. Used them on a 21 harely street glide. Not much work required to fit in the stock pods. Also easy to tune very strong vocals.
