  • 130 mm Composite Sandwich Woofer Cone
  • 25 mm Titanium Dome Tweeter
  • 160 W Peak Analogue AB Amplifier
  • Elliptical Modelled Dispersion Waveguide
  • Wide Horizontal Dispersion


The Neumann KH 120-A Studio Monitor combines a 25 mm titanium fabric dome tweeter powered by 50 W RMS (80 W peak) of analogue amplification with a 130 mm long throw composite sandwich cone bass driver powered by 50 W RMS 80 W peak) analogue amplification with dual front panel bass ports. The two speaker drivers are mounted in an elliptical mathematically modelled dispersion waveguide for smoother off-axis response and a more forgiving sound signature in different acoustical environments.

The front panel is made from one piece without discontinuities to reduce diffraction with protective metal grills and the cabinet is made of magnetically shielded aluminium to reduce resonances, improve heat dissipation, and extend the operating lifetime of the unit. The monitor is suitable for professional tracking, mixing, and mastering applications in broadcast, project, and post-production studios.

The system delivers a free field frequency response of 52 to 21,000 Hz with 4-position bass, low-mid, and treble acoustical controls for tailoring the response to different rooms and an input gain control from 0 to -15 dB. The front panel Neumann logo functions as an LED indicator for power and clip/limiting but can also be dimmed for light applications and for use when placed behind screens. A variety of wall, ceiling, truss, subwoofer, stand, and surface mounting options are available through a range of accessories (sold separately).

Australian Shipping Via DHL
DHL offers a great express shipping service to Australia from New Zealand. We are proud to be able to offer express shipping to main cities on the east coast of Australia, within the same timeframe ( If not quicker ) than local Australian courier companies. Prior to the Covid-19 outbreak, service standards for these main centers was overnight. However these services have been impacted greatly, and as such the overnight service has been suspended. Overnight shipping will likely resume once things have returned to normal.

Qualifying main centers include:

  • Brisbane
  • Sydney
  • Adelaide

Whilst this service is extremely efficient and will likely be delivered within 1-2 days 99.9% of the time, it cannot be guaranteed. In the case where something were to go wrong with your delivery and it doesn’t arrive within the specified time frame, in most cases it will be delivered by the next day.

While not all major cities are eligible for overnight delivery, they still benefit from this great service. Other centers throughout Australia will have a typical delivery ETA of 2-4 days. (Excluding rural delivery address where this ETA can be extended to an additional three or more days).

If you require urgent shipping and you don’t reside in one of the cities stated above, please contact us and we can find a solution that works best for you.

Please Note: Shipping via DHL is not available to PO boxes and/ or parcel boxes etc.
