Positioning the monitors

In order to get the best performance from your Dynaudio monitors, care must be taken when positioning them in the listening environment. The room greatly affects the sound so the position and angle of the monitors relative to the walls, ceiling and floor is critical in any listening environment.

Acoustic axis

The acoustic axis is an imaginary line passing through the centre point on the monitor. As shown in Figure 2 , use this method for measuring the distance and angle to your listening position. The point is positioned half the distance between the boundary of the tweeter and the boundary of the woofer or midrange driver.

Figure 2: The acoustic axis (1)

The Core 7 is designed to be positioned vertically and pointed directly at the listener.

The Core 47 has two versions with the woofer on either side of the tweeter and midrange drivers for either horizontal left or right side placement.

The Core 59 is designed to be used in either vertical or horizontal position by rotating the Orbit Baffle.

The Core Sub is a side-firing subwoofer where the front baffle has the logo and LED indicator.

Room boundaries

Each surface in the room constitutes a boundary for sound; floor, walls, and ceiling. Room boundaries will reflect sound to one degree or another depending on the surface material; hardwood, drywall, carpet etc. If possible, please avoid placing monitors very close to any boundaries. The closer a monitor is to a room boundary, the more anomalies you may experience in the low-frequency response of the system. Placing a monitor close to more than one boundary (e.g. in a corner) creates even worse problems in many cases.

Conversely, placing monitors exactly halfway between room boundaries may over-excite fundamental standing waves in the room, making the bass response less reliable. This is also the case with regard to the listening position. These room anomalies are always present, but proper placement of the monitors according to the listening position will reduce their effect.

A good rule of thumb is to place monitors somewhere between one quarter and one third of the distance between room boundaries as shown in Figure 3.

Also make sure the listening position is not right in the centre of the room if possible. In larger rooms, this is less critical than in small rooms.

Sometimes, the ideal positioning is not possible to achieve. Limitations in terms of space and other equipment or furniture in the room may influence several aspects of the monitor position. In short, the idea is to do the best you can with the limitations you have.

Listening distance and mounting

The Core 7 monitors are designed as nearfield monitors. Nearfield monitors should be placed relatively close to the listener, between 1 and 3 metres.

The Core 47 and Core 59 can be used both as a near or midfield monitor, positioned between 1.5 to 4 meters.

When used as an LF extension, the Core Sub should be placed with the front baffle at the same distance to the listener as the other monitors. If the Core Sub is used in a surround or immersive setting, follow the guidelines for that application.

Monitors on the desk or console

These monitors are designed to work well in a variety of positions, including when placed closely and on the work surface in front of you. If they are resting on a desk or a console meter bridge, they may be tilted up or down to aim at ear level with great results. The first Position switch should be set to “Desk”.

Monitor stands

Placing your monitors on stands behind your workstation or console is very common and gives you more control over the distance, angle, and position within the room. The first Position switch should be set to “Anechoic” so long as the monitors are not closer than 50 cm from any wall or ceiling.

Core Mounting bracket

The Core Mounting Bracket is designed to facilitate mounting of the Core 7, 47, and 59 either on a wall, ceiling, or even as a desk stand. This bracket is compatible with many standard K&M accessories for more mounting options.

Soffit Mounting

In a soffit mount design, the monitors are placed within cabinets built into the walls of the listening room. This will provide a more phase coherent bass response and better imaging if designed properly. If the Core monitors are soffit mounted, the first Position switch should be set to “Soffit”. This will compensate for the increase in bass output from the soffit design.

When soffit mounting Core monitors, allow 12 mm of space above and below for proper ventilation of the amplifier. The Core Sub requires an additional 50 mm or more of clearance on either side for driver excursion.

Listening angles

Usually, the monitors should be placed so that the drivers are oriented vertically, with the tweeter directly above the woofer or midrange driver. This orientation ensures correct time alignment between the high and mid frequencies as they arrive at the listener. The Core 59 incorporates the Orbit Baffle, which allows the tweeter and midrange assembly to be rotated to multiple orientations so that you are free to place the woofer below, to the side or even above this assembly.

Horizontal angle

The monitors should be placed so that they create a 60-degree angle between the monitors, as shown in Figure 4.

Figure 4: monitor angle 60 degrees

The easiest way to accomplish this without measuring the angle is to create an equilateral triangle between the monitors and the listener. In other words, the distance between each monitor should be equal to the distance from each monitor to the listener. The Core 59 can be positioned with the woofers inside (recommended) or outside, depending on how the equilateral triangle can be achieved best. Make sure to take measurements from the acoustic axis of the monitor.

An easy method to do this involves a measuring tape and some string. With the tape measure, check that the monitors are not placed further away than 3 metres for free field reference listening level.

  1. Once you have initially placed the monitors, take the string holding one end at the monitor’s acoustic axis and stretch it out to the listening position.
  2. Measure the distance to a single point behind your head where the strings from both sides would meet.
  3. Mark this point with a marker.
  4. Do this again for the other monitor to ensure that they are both the exact same distance from the listener.
  5. Use the string to measure the distance between each monitor. This should also be the same, forming and equilateral triangle between the two monitors and the listener.
  6. Make adjustments as necessary to place the listener and monitors at the same distance from each other.

Vertical angle

The vertical angle of the monitors should orient the monitor directly toward the listener’s ear level. If the monitor is placed higher than the listener, they should be angled downward. Conversely, if the monitor is below the listener’s ear level, they can be angled upward to point at the ear as shown in Figure 5.
