KH 310 II
The Neumann KH 310 II R+L is a pair of three-way, DSP-controlled active nearfield studio monitors with a sealed cabinet and 525 W of total amplification. It is aimed at engineers who need detailed midrange and accurate stereo, multichannel or immersive monitoring, with optional MA 1 room correction.
- Three-way active nearfield monitor, sealed cabinet
- 525 W total Class D amplification across three amps
- Analog XLR plus AES3id digital input and output on BNC
- DSP with MA 1 automatic room alignment support
- Free-field linearity ±0.6 dB from 100 Hz to 10 kHz
- Same form factor as the original KH 310

The KH 310 II is a redesigned version of the KH 310 three-way nearfield monitor. It uses an 8 1/4" woofer, a 3" soft-dome midrange driver and a 1" tweeter in a sealed cabinet, driven by three Class D amplifiers with 525 W of total power. Compared with the original model, the maker states a 5 dB higher maximum SPL, lower distortion and free-field linearity within ±0.6 dB between 100 Hz and 10 kHz.
An integrated DSP provides crossover, delay, equalisation and linear-phase FIR correction, and it supports MA 1 Automatic Monitor Alignment for frequency and phase correction in the room. Three acoustic controls (bass, low-mid and treble) and four output level settings allow adaptation to the listening position. Network control is available through MA 1 software.
Connections are an analog XLR input and AES3id digital input and output on BNC connectors. The cabinet keeps the dimensions of the original KH 310, so it can replace existing installations. It works with Neumann KH subwoofers for stereo, multichannel and Dolby Atmos setups. This listing covers the R+L pair; left and right monitors are also sold individually.
