Neumann KH 310 II L

From Klein plus Hummel to Neumann: The 3-Way Legacy, Modernized for 2026

The KH 310 II is part of a very special history: that of active 3-way monitors popularized as early as 1967 by Klein & Hummel, a legacy that Neumann has evolved without ever compromising on the essentials. With this new generation, the goal is clear: to maintain the sense of neutrality and "effortless" playback that made the KH 310 A famous, while pushing the platform further thanks to a modern DSP architecture, better unit-to-unit coherence, and improved measured performance.
As the LEFT version, this monitor is intended to serve as the left channel of a stereo pair or a multichannel system. This is an important point in immersive setups, where predictability from one speaker to another and image stability are as crucial as the frequency response curve.

Who Is the KH 310 II LEFT Designed For?

The Neumann KH 310 II LEFT targets studios that require critical monitoring in medium to large spaces, without compromise on translation. It excels in recording, music production, post-production, broadcast, and mastering, as well as in immersive audio configurations (Dolby Atmos and other formats), where tonal coherence and localization precision are decisive.
If you work on fine decisions (low-mid balance, vocal intelligibility, reverb placement, music bus density, master dynamics), the 3-way design allows for stable playback at various listening levels, with clear separation of frequency bands. The result: fewer doubts, less backtracking, and mixes that "hold up" better on a wide range of systems.

What Really Changes: DSP, ELFF, and Increased Performance

The KH 310 II is not just a cosmetic update: almost every element has been optimized. However, Neumann has retained a cornerstone, its 3-inch soft dome midrange driver, renowned for its tonal quality and precision. It is often in this range (where vocals, guitars, snares, presence reside) that a monitor reveals itself, and this is precisely where the KH 310 built its legend.

More Headroom, Less Distortion, More Confidence

Thanks to high-efficiency Class D amplification and an advanced limiter structure, the KH 310 II delivers more power than the previous generation: 300 W for the woofer (versus 210 W), 160 W for the midrange (versus 90 W), and 125 W for the tweeter (versus 90 W). In practice, this translates to extra margin on peaks and more composed performance when the session gets dense, without hardening the listening experience.
Neumann also announces a reduced total harmonic distortion across the entire frequency range, as well as a 5 dB higher SPL level (measured in half-space and free-field) compared to the current KH 310. This is exactly the kind of improvement that makes a difference in control rooms: decisions remain clear at realistic levels, without the low end becoming muddy or the highs becoming harsh.

ELFF: Cleaner Bass Even at High Excursion

The 8.25-inch woofer adopts ELFF technology, designed to achieve extremely low distortion, even when excursion increases. Add to this an increased linear excursion and reduced intermodulation distortion: the low end stays clear, kicks retain their definition, and complex basses (808s, synths, controlled subs) settle faster.

32-bit DSP and MA 1: A Monitor That Integrates With Your Room

The KH 310 II features a full 32-bit DSP signal chain: precise system alignment, advanced processing, and compatibility with MA 1 automatic alignment. The benefit is twofold: on one hand, you exploit the monitor's full potential in real environments (even treated, no room is perfect); on the other hand, you get a consistent baseline to transition from stereo to multichannel without "coloring" each speaker differently.

Analog and AES3id Inputs: Ready for Modern Workflows

With its analog and AES3id (BNC) digital inputs, the KH 310 II LEFT connects equally well to traditional chains and more broadcast- or post-production-oriented setups. This flexibility, combined with improved unit-to-unit consistency, facilitates building predictable multichannel systems and a highly precise stereo image.
Finally, good news for studios already equipped: the external dimensions remain identical to those of the KH 310 A. You keep your integration constraints (furniture, stands, placement) while upgrading to a more powerful generation.
