PRV Audio's 5MR450-NDY neodymium-powered midrange speaker features a sensitivity of 95 dB (2.83V/1m), weighs less than 3 pounds, and its 140 to 16,000 Hz frequency response allows it to be used for full range, single driver applications!
Key Features
  • Full copper sleeve on the pole-piece for low distortion and inductance
  • Low inductance for great transients and extended high frequency response
  • High EBP for horn-loaded enclosures
  • Naturally damped response for reduced top-octave ringing
  • Wide bandwidth that reaches out to 16 kHz and higher

Overview

PRV Audio 5MR450-NDY 5" Midrange Neodymium Woofer 8 Ohm

The 5MR450-NDY, from PRV Audio, is built from the ground up to be a class-leading 5" midrange for pro audio, high output car audio, and high fidelity home audio applications. Its high-powered neodymium radial slugs immerse the voice coil in a strong magnetic field, providing extreme control and high senstivity. Additionally, the pole piece copper has a copper sleeve which lowers inductance thereby improving high frequency response.

Not only does the unique motor design keep the mounting depth at less than 3" (great for car doors), it also reduces distortion. With a usable, extended frequency response from 160 to 16,000 Hz, this midwoofer also works great as a high output, full range satellite speaker.

A bumped backplate, vented magnet assembly, 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.
