6.5” High-Sensitivity Professional Midrange Loudspeaker with Neodymium Magnet 

Neodymium Precision
The 6PRO500NMR-4 is a 6.5” high-sensitivity professional mid-range built for extreme output and clarity. With 250W RMS and 500W MAX power handling, this 4-ohm driver delivers aggressive, detailed mids that cut through the loudest systems.

Pure Projection
Powered by a neodymium motor, the 6PRO500NMR-4 delivers an impressive 103 dB sensitivity and a focused 120 Hz–17 kHz frequency response. Every vocal and instrument stays sharp, present, and commanding at high volume.

Lightweight, Loud, Reliable
An aluminum basket provides structural rigidity while keeping weight down. The cloth surround ensures durability, and its 2.6” mounting depth allows for versatile installation across a wide range of applications.

Pro-Level Performance
A 1.5” Kapton voice coil with CCAW winding ensures efficient heat dissipation and consistent power handling. The copper demodulating ring enhances clarity while reducing distortion, keeping your mids clean even under heavy demand.

Engineered to Be Heard
Designed for high-output applications, the 6PRO500NMR-4 is built for serious sound enthusiasts who demand projection, efficiency, and reliability. Available in 6”, 8”, and 6x9” options.
