From Neumann USA
The KH 310 II introduces the next era of precision to Neumann’s iconic three‑way monitor line. While maintaining the sonic character that made the original KH 310 a reference in countless studios, nearly every internal component has been redesigned to further improve real‑world performance. A new amplifier platform increases total power to 525 W. This enables cleaner output with even lower THD and 5 dB higher max SPL. Tighter component integration and production tolerances achieve ±0.6 dB linearity from 100 Hz to 10 kHz for razor sharp imaging.
At the heart of the KH 310 II is an DSP architecture that supports MA 1 Automatic Monitor Alignment, ensuring precise frequency and phase correction for consistent translation in any room. Analog and digital AES3id inputs (BNC) enable seamless integration with modern workflows, including Neumann’s new generation of KH subwoofers and monitor control solutions.
The closed-box design continues to deliver the tight, time‑accurate bass response that engineers rely on for trustworthy low‑end decisions. The legendary 3" soft‑dome midrange driver remains the benchmark for vocal definition and mid band intelligibility. Combined with lower distortion and more headroom, the KH 310 II allows for longer fatigue‑free sessions and faster decision‑making thanks to its increased transparency.
Fully compatible with previous KH 310 installations, the KH 310 II offers a future‑ready foundation for stereo and immersive setups, preserving Neumann’s tonal signature while delivering meaningful improvements in every key parameter.
Features:
- Re‑engineered 3‑way design with lower THD and higher SPL
- Razor-sharp imaging due to extremely low tolerances (±0.6 dB)
- DSP platform with MA 1 alignment and digital input
- Closed‑box design for time‑accurate, low‑delay tight bass
- ELFF woofer for low distortion at high excursion
- Backward‑compatible form factor for KH 310 installations
