The PRV Audio Pro Audio Loudspeaker, 5MR450-NDY midrange woofer offers outstanding durability and a smooth midrange response through 16kHz. This woofer is perfect for home Hi-Fi installs, including bookshelf, satellite, surround sound speakers and even the home studio monitors. It is a great option for three way cabinets requiring additional midrange support.

The high end neodymium magnet assembly was chosen to increase sensitivity and power handling. This neodymium is attached to a sturdy reinforced cast aluminum frame to ensure a solid support structure for long lasting play in most any environment. Its light weight of only 1.21 lbs helps keep your enclosures light and is a great use for use for car doors and installers looking for high SPL midrange and upper midrange responses. For car audio applications, a 4 ohm model is also available.
