A two-way monitor with biamplification

The Neumann KH 120 loudspeaker system is a two-way monitor system 5.25-inch composite sandwich cone . This sound precision is also due to the titanium fabric dome tweeter 1 inch magnetic shielding

The Neumann KH 120 subwoofers do not have an integrated amplifier, but 80 Watt AB power with thermal shielding . This characteristic limits the risk of overheating and provides stability to the Bass speakers.

You are probably thinking that a subwoofer powered with only two amplifiers must produce sounds poorly? You are on the wrong track. With its two amplifiers, the Neumann KH 120 produces a clear and truly precise sound that you will struggle to differentiate with a subwoofer with three amplifiers.

Thanks to a robust aluminum design, the speaker housing is resonance-free. In addition to this, both the subwoofer and the tweeter are protected by a high-strength metal grille.

By the way, you can also discover our test guide and review of the Genelec 8040 BPM . This guide presents the sound quality of this monitoring speaker, its technical characteristics, its positive and negative points, as well as its mode of use, and our opinion on the 8040 BPM from Genelec.

Mathematically Modeled Dispersion or MDD

The Neumann KH 120 loudspeaker is equipped with a waveguide with mathematically modeled dispersion ( MDD ). This allows the speakers to distribute sound more clearly and directly horizontally and vertically , in rooms with different acoustic variations.

This dispersion guide also gives a very regular response and even off-axis. A character that allows it to adapt to all conditions and acoustic environments.

Yet another great advantage of this subwoofer is that you can use it in any room in the house, regardless of its size. The horizontally distributed sound range is wider. It is therefore easier to place it in a more or less narrow place without risking destroying the sound.

On the other hand, vertical sound disperses more narrowly. This reduces the amount of distortion caused by a table, musical instrument or any object that can degrade sound quality. It is also for this vertical range of sound that the Neumann KH 120 loudspeakers must be placed at height.

Of course, the sound pressure in each room also has a big impact on sound quality. Therefore, you must always take acoustic treatment into account during your listening sessions. Especially since the acoustics of the studio are also important if you are doing a recording session.

The acoustic conditions and vibration of the room create the conditions for perfect sound recording. It is therefore essential to accompany the Neumann KH 120 with deep sound-absorbing membranes and diffuser front panels . Also, if your studio contains several glass surfaces, you must place thick and dense acoustic curtains in front of these surfaces.

A wide frequency range

The Neumann KH 120 monitor has a wide frequency range that can even reach very low levels, down to 52 Hz . You will no longer need a specific power amplifier for low frequencies.

But as with every subwoofer and monitoring speaker, the size of the room is essential for the sound system, and the place of the speaker. Generally, when you have a large studio, you will probably need a line amplifier like the Chandler Limited Redd 47 or a subwoofer for your Neumann KH 120.

Zoom on the sound quality Neumann KH 120

The Neumann KH 120 monitor is one of those speaker monitors with very clear sound for a very affordable price. The sound of this monitor is very clean thanks to flat frequency transmission . It responds very well to low frequencies, but also to high frequencies.

The size of the Neumann KH 120 monitor makes you hesitant about its volume? Don't worry, its volume can reach 114 dB whether your studio is small, medium or very large. On the other hand, large studios may request an additional subwoofer. But it also depends on the number of speakers.

The bass sound of the Neumann KH 120 is very intense and excellent . With a very honest sound, it produces both bass and treble sounds. Because of this very clear sound, there may be errors in your mixing or mastering work. However, you can very well correct them with your PC speaker.

Technical characteristics of Neumann KH 120

If the Neumann brand is better known for the design of microphones (only citing the famous Neumann TLM 102 and the Neumann U67) for sound recordings , it has now launched into the creation of loudspeakers which have an output of its very precise.

The Neumann KH 120 speaker monitor features German sound technology. Which gives it this great sound precision . Every little detail and characteristic of the hi-fi speaker is carefully studied so that the product is of quality and functional. It is therefore a very well designed monitoring speaker.

Despite the fact that it is compact, the Neumann KH 120 monitor is one of those microphones that produce excellent sound, like picture (with its Focal Shape 65 speaker ) or Dolby. The Neumann KH 120 hi-fi speaker can also be used as an amplifier or rear speaker with the multiroom system . For this, you must use a TNT HDMI tuner since the Neumann KH 120 is not a Bluetooth speaker.

Our opinion on the Neumann KH 120 microphone

The Neumann KH 120 speaker is one of the preferred monitors for home studios. It produces very clear, precise and honest sound for faithful and active reproduction on stage.

Users have expressed a little doubt about its size, but it still performs well in the depths of the spectrum. It has no difficulty reproducing low or high frequency sounds, even at very high volumes.

If for a large studio it is better to use an additional subwoofer, you can still get low frequency sound. Indeed, the Neumann KH 120 already has an integrated amplifier.

Thus, the Neumann KH 120 active studio monitor is a recommended microphone for reproducing good sounds during mixing and mastering.
