The 8MR500-NDY v2 series was designed from the ground-up to become the new standard in vocal reproduction in compact enclosures. The new and improved version 2 meets the demand for an extreme lightweight and powerful mid range loudspeaker. Great addition to the MR Series!

Built for loud and clear vocal performance in tight, compact spaces. The new Version 2 has improved its motor and basket design. Now featuring a new copper-clad aluminum voice coil for low moving mass to increase efficiency.


  • 2″ DUAL layer CCAW voice coil wound on Kapton former, 4 ohms
  • Strong Vocal response on vocal range from 300 to 850hz 
  • 500 watts continuous program power rating produces high acoustical output
  • Great as door speaker in car audio application
  • Number one choice for motorcycle bag lids application because of its lightweight
  • Replacement for 8MR500-NDY-4, improved vocal response and voice coil
  • Also available in 8 ohms 8MR500-NDY v2


The new 8MR500-NDY v2 series has everything you want in a mid range pro audio loudspeaker, without sacrificing performance we have designed a shallow and versatile footprint with only 3.03” of mounting depth.

Its high energy, rare-earth neodymium motor, combined with other fine materials to resolve the finest details in audio, demanded by most audiophiles in the car audio and motorcycle custom builders.


This full-featured mid range incorporates a 2” double layered copper clad aluminum wire voice coil, and a symmetrical inductance profile.

Everything about this speaker has been designed for reliable and consistent high output levels even when driven to its limit, allowing you to achieve high fidelity sound at low distortion with the best possible listening experience.


Its low-mass yet stiff cone helps provide clean, detailed, high-impact sound reproduction. Supporting the cone is a triple roll treated cloth surround designed both to ensure the speaker’s extended frequency response to 9,000Hz and strong vocal presence from 300 to 850hz.

This driver is perfect for applications where weight and space is limited, such as custom doors panels, motorcycle fairing and saddlebags, making this driver a popular speaker choice among high output car and motorsports audio enthusiasts.

    Q Noticed the non vented voice coil. Any concerns with the longer excursion and power handling vs the 8MR500-NDY-4?
    Asked by Victor Hernandez on December 2, 2019 9:20 pm

    Two main differences between this version 2 speaker and the original are the voice coil and the new compact, more powerful, neodymium motor. The original 8MR500 had a 1.5" single wound voice coil vs the 2" double wound voice coil in the V2. This combination of the more durable 2" voice coil and improved motor does not require the usage of a ventilation system as this new design can handle the power much easier than the old design with the 1.5" voice coil. The cone and surround remain unchanged from the original giving you the same sound with better reliability and power handling than before.

    yes you will gain alot of output from 250hz all the way to 1500hz about 2dB +, and the we have increased the voice coil to 2", increasing power handling and also making it more reliable

Loudest door speakers!

Buddy of mine bought the PRV speakers for his car and was really happy (search PRV Audio on Steve Meade Designs). Had to get these once they dropped.Been smiling since I installed 'em. Needless to say, my buddy is going to outdo me and get the 10" PRV mids soon.
