Features
The 8MR400-NDY-4 offers slim design for narrow and shallow profile installation without sacrificing performance. This professional Midrange Neodymium magnet loudspeaker delivers smooth clear vocals that will impress any listener and the efficiency makes it easy to power; all thanks to a specially designed light weight cone which delivers very smooth Midrange and Midbass response through the upper Midrange area of an amazing 8.5 kHz.
With only 2.95” of depth, car audio enthusiasts gravitate towards this driver for use in their systems when looking for a lightweight and shallow Midrange that can sustain long hours of extreme operation on a sealed enclosure and is a perfect option for Midrange driver replacements in three way cabinets. It also has become a popular choice for home audio Hi-Fi speakers.
The Neodymium magnet assembly attached to a sturdy reinforced steel frame completes the 8MR400-NDY-4 to ensure a solid support structure, for long lasting play in most any environment and its light weight of only 1.6lbs helps keep your enclosures and car audio installs light.

Customer Reviews
These 8 in speakers are amazing sound clear and super loud still working in seting up th DSP
I added a subwoofer enclosure in the trunk of an 07' Mustang GT and replaced the stock 8" subwoofers on the 2 front doors with a pair PRV's. The door panels just happen to have a factory 8" subwoofer enclosure that these speakers fit right into perfectly. They sound fantastic!
