KH 350

Name: Neumann KH 350
Brand: Neumann

Studio Monitor

From Neumann:

The KH 350 is a high performance three way monitor combining deep low frequency extension and tightly controlled dispersion with advanced DSP integration. Optimized for medium-sized rooms and immersive environments, it delivers full range accuracy, refined midrange detail, and seamless room alignment via MA 1 (optional).

The KH 350 expands Neumann’s portfolio into true midfield monitoring, delivering the power, low frequency authority and control required for listening distances ranging from 1.2 to 3 m (4 to 10 ft) and immersive production environments. As it shares Neumann’s consistent tonal DNA, the KH 350 may be combined with other KH-Line monitors in immersive setups.

The KH 350 impresses with deep and powerful low-end response, enormous headroom, and exceptional linearity across the entire musical spectrum (32 Hz – 20 kHz ±1.25 dB).
