PRV Audio 6MR500-NDY-4 6-1/2" Neodymium Midrange Woofer 4 Ohm

PRV Audio
Part #294-2706  
Model: 6MR500-NDY-4
Built for loud, clear vocal performance in tight, compact spaces, PRV Audio's 6MR500-NDY-4 neodymium-powered midrange features a sensitivity of 100 dB (2.83V/1m) and weighs about 3 pounds! 4 ohm impedance.
Key Features
  • Wide bandwidth that reaches out to 15 kHz and higher
  • Naturally damped response for reduced top-octave ringing
  • Low inductance for great transiets and inproved high frequence response
  • High EBP for horn-loaded enclosures
  • High 96 dB sensitivity means more sound per watt

Overview

PRV Audio 6MR500-NDY-4 6-1/2" Neodymium Midrange Woofer 4 Ohm

The 6MR500-NDY-4, from PRV Audio, is made to be a class-leading midrange woofer in the pro audio realm, as well as high output car and home audio, thanks to high-power neodymium radial slugs that immerse the voice coil in a strong magnetic field.

Not only does the unique motor design keep the mounting depth at less than 3" (great for car doors), it provides superior speaker control for reduced distortion. Additionally, the pole piece copper has a copper sleeve which lowers inductance thereby improving high frequency response. With a usable, extended frequency response from 104 to 12,500 Hz, this midwoofer also works great as a high output, full-range satellite speaker.

A bumped backplate, vented magnet system, vented pole piece, Kapton® former, open cast-aluminum frame, and treated-cloth surround allow for high power handling, while protecting this driver from extreme transient power peaks.
