Built to offer precise audio dispersion, the Neumann KH 420 G is an excellent active studio monitor with a great power reserve. Characterised by its sleek form, ability to fit in small spaces, and neutral performance in diverse acoustical environments, this audio speaker reproduces every sound element with high clarity while eliminating the negative effects of reflection and resonance.

Neumann KH 420 G Key Features:

  • Offers clear and neutral audio output for every sound element
  • Protected Class AB amplifiers with 330 W constant power output
  • Vertical driver placement for narrow dispersion and reducing resonance
  • Ideal for use in post-production, recording, mixing, and mastering
  • High sound pressure endurance capability if up to 122.4 dB
  • Outstanding bass quality that lowers down to 26 Hz
  • Prevents audible resonance at lower frequencies for clean results
  • Prevents audible resonance at lower frequencies for clean results
  • LRIM materials manufactured chassis eliminates intermodulation distortion
  • Neodymium magnets ensure better transient response and less disturbance
  • Alloy fabric dome manages high-frequency reproduction
  • MMD waveguide technology for a smooth off-axis response
  • Great midrange frequency reproduction for vocal and speech
  • Magnetic shielding reduces air noise and enhances rocking modes
  • Equipped with linear pistonic motor for low harmonic distortion

Expanded Neumann KH 420 G Key Features:

Advanced Hardware

Housing an advanced hardware technology, the Neumann KH 420 has a composite sandwich cone bass driver combined with versatile ELFF (Extremely Linear Force Factor) to damp the break-up modes, maintaining low distortion even at high sound levels. You can monitor every single element of sounds right down to the subtlest of details. At the same time, this intuitive speaker has magnetic shielding that controls harmonic distortions. Adding to its versatility is the flow-optimised die-cast basket that helps to reduce air noise and promotes rocking modes.

Low Resonance Build

The KH 420 boasts construction from LRIM (Low Resonance Integral Materials), which helps to reduce the standing wave resonance inside the cabinet. In addition, this three-way cabinet features mechanically modelled components that prevent intermodulation distortion in the midrange for clean sound, meaning the speaker does not offer humming and rumbling noises. The robust and tight construction of this cabinet further reduces the overall resonance of sound as well as the cabinet itself.

Parametric Equaliser

There is another great feature equipped by this professional monitor and that is its built-in parametric equaliser technology. This intuitive technology ensures complete control in diverse acoustical environments for a precise sound output no matter the type of sound element. Introducing three frequency ranges, this feature provides precise control over the equalisation of any type of sound. Best of all, this automatic feature can be bypassed or customised as per the requirement.

Bass Reflex Ports

Featuring large and high-capacity bass reflex ports, this studio monitor has a fast bass transient response. Included pipe resonance damping further reduces bass compression at higher output levels, promoting better sound quality. Also, there is absolutely no colouration from the organ pipe, meaning the speaker does not offer any kind of resonance or disturb your music monitoring sessions. Additionally, the monitor can be flush-mounted, thanks to these reflex ports.

Increased Reliability

For providing constant 330 W power output, this monitor uses an AHT (Accelerated Heat Tunnelling) system with a dedicated heat sink to increase the reliability during longer run times. In addition, there are fast-acting thermo limiters that increase reliability and overall performance of the woofer, midrange, tweeter, voice coil, and power amplifier. With large headroom and overheating limit, this speaker performs with assured reliability and safety.

What's in the box?

  • 1 x Neumann KH 420 G
  • 3 x AC Power Cables
  • Limited 1-Year Warranty


Is there a protective grille on the monitor or do I have to buy one separately?

There is a protective grille on the monitor. However, you can purchase the Neumann GKH 420 B metal grille to protect this monitor from minor to moderate mechanical damage.

What is MMD technology? How does it help?

The Mathematically Modelled Dispersion (MMD) technology waveguide is designed to disperse the sound output in a wide horizontal way or a narrow vertical way for accurate sound performance from all types of positioning perspectives.

Does this monitor overheat due to prolonged use?

This monitor features large class AB amplifiers that have a large headroom and overheat limiting. In addition, this speaker houses an electronic panel with dimension integrated Accelerated Heat Tunnelling heat sink that prevents overheating of the complete system, even during prolonged use.

What is a parametric equaliser?

The parametric call Azhar is designed to automatically refine sound elements as per the acoustical environment. It offers you the freedom to manually set the sound output of bass, treble, and midrange with extreme ease.

Can you pair this monitor with other monitors of the same model?

You can easily pair this monitor with multiple speakers of the same model, allowing you to monitor stereo and mono sounds.

The Buy Now Pay Later option comprises a 36 month loan following a six month deferral period.

During the six-month deferral period, it is possible to pay off the loan, either by way of a lump sum or in smaller amounts. If the loan is partially repaid within six months, the remaining interest will be adjusted to reflect the new balance. If the loan is fully repaid within the six-month deferral period, then no interest is payable, however, a £29 early settlement fee is payable in respect of repayments within these six months.

Following the six-month deferral period, Novuna Personal Finance will initiate a monthly direct debit payment for the remaining duration of the loan. Interest will be charged at a rate of 18.9% APR on outstanding balances (backdated to the first date of the loan). Novuna Personal Finance will send a reminder letter approximately one month before the six-month deferral period is due to elapse.
