Images of the Neumann KH120A Monitor
The front of the KH120A is very compact with the tweeter, the tweeter's waveguide, the on/off logo which lights red when the limiting circuit is active, the woofer, and the two ports filling the entire panel.
Concerning ports, the total surface area and depth are the main considerations as opposed to the shape and actual number. Consequently, the KH120A has two ports shaped in such a way that they can fit close to the woofer and take up the minimum amount of space at the front. Had there been just one circular port (with the same surface area and depth as the two roughly triangular ports) the size of the cabinet would have to have been larger. A nice piece of engineering from Neumann.
The distinctive speaker-shaped metal grill over the woofer offers permanent protection as it cannot be removed. The tweeter is also protected by a strong metal grill.
The back of the Neumann KH120A (pictured right) is shown in greater detail and from different angles in the pictures below.
The two holes at each side of the cabinet have bolts that secure the front panel to the rest of the housing. The two holes vertically aligned at the centre are for mounting the speaker on a bracket.
Fins in the cast aluminium cabinet near the top, below the acoustic controls, act as heat sinks. With normal usage I have found that they barely get warm.
The recessed lower part of the cabinet contains the on/off switch, the IEC mains input socket, the XLR signal input socket, and four small switches for the logo illumination settings and ground lift, all located on the upper inverted shelf, out of view here but pictured in more detail in one of the photos below.
The top of the KH120A (below) showing the acoustic controls on the left, which add flexibility to placement, and the input and output controls on the right. The output level is in the form of a switch whereas the input gain control is a regular potentiometer.
The lower part of the rear of the cabinet is recessed. The on/off switch is on the left, then the IEC socket, followed by four small white switches to control the logo illumination on the front panel and ground lift. Finally, there is the XLR socket on the right. There are no other inputs.
Looking up at the recessed section at the rear of the monitor. In use the IEC mains and XLR cables enter their sockets vertically. The reason for this I would guess would be to allow greater flexibility in positioning and mounting, since no cable protrudes horizontally.
The KH120A is undoubtedly a first-rate studio monitor, but it's not the only professional monitor in the £1000 price bracket so it's important to audition others before deciding if the KH120A is the best one for you. Buying speakers on the basis of a review only is not recommended. Whenever buying any audio equipment it's important to listen very carefully and use your own judgement.
