Product Overview
6x9” High-Sensitivity Professional Midrange Loudspeaker with Neodymium Magnet
Projection Power
The 69PRO400NMR-4 is a 6x9” 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 69PRO400NMR-4 achieves 100 dB sensitivity with a 100 Hz–17 kHz frequency response. Its 6x9” cone area 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 2.9” 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 69PRO400NMR-4 delivers projection, efficiency, and reliability. Available in 6”, 8”, and 6x9” options to match your system’s needs.
