Neumann KH 750 AES67

Neumann KH 750 AES67 – compact DSP-controlled subwoofer with redundant Audio-over-IP (AoIP) integration, 10” ELFF™ driver, 256 W power, and full network control.

The Neumann KH 750 AES67 is a high-performance compact subwoofer designed for seamless integration into AES67-compliant IP-based studio networks. Featuring a 10” long-throw driver with ELFF™ technology and a powerful 256 W amplifier, it offers extended bass response, tight transient reproduction, and DSP-based alignment capabilities for all connected KH line monitors. With redundant AES67 ST2110 support and analog/digital inputs, the KH 750 AES67 is perfect for use in professional music, broadcast, and post-production environments. It supports Neumann’s MA 1 room calibration system and provides network control via Neumann.Control software.
