PRV Audio 8MR500-NDY-4 v2 (Single Unit)

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.

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.
