Product Overview
6.5” High-Sensitivity Professional Midrange Loudspeaker with Neodymium Magnet
Powerful Projection
The 6PRO400NMR-4 is a 6.5” high-sensitivity professional mid-range built for aggressive output. With 200W RMS and 400W MAX power handling at 4 ohms, this speaker delivers strong, forward mids that cut through loud, high-output systems.
High Sensitivity
Powered by a neodymium motor, the 6PRO400NMR-4 achieves 100 dB sensitivity with a 120Hz–17kHz frequency response. Its paper cone increases surface coverage, giving vocals and instruments more presence and projection.
Durable Construction
The steel basket provides solid structural support for daily or high-output builds. The cloth surround ensures durability under heavy demand. With a 2.6” mounting depth, this speaker offers versatile installation across a wide range of applications.
Built for Clean Output
A 1.5” Kapton voice coil with CCAW winding improves efficiency and heat management. The integrated copper demodulating ring reduces distortion, keeping your mids tight, controlled, and competition-ready.
Designed to Be Heard
Engineered for serious sound enthusiasts, the 6PRO400NMR-4 delivers projection, efficiency, and reliability. Available in 6”, 8”, and 6x9” options to match your system’s needs.
