close to the listener, between 1 and 2 meters. LYD 48 can be used both as a near or mid field monitor. The ideal
listening distance is between 1.5 and 2.5 meters.
Speakers on the Desk
These loudspeakers are designed to work well in a variety of positions, even very close, placed on the work
surface in front of you. If they are resting on a desk or console, they may be tilted up to aim at ear level with great
results.
Speaker Stands
If you need to place your speakers on stands behind your work surface or computer screens at a greater
distance, it is recommended that you use a subwoofer to augment the low frequency response. This will help the
speaker system achieve a reasonable volume without overdriving the speakers.
Listening Angle
To begin with, the speakers should be placed so that the drivers are oriented vertically, with the tweeter directly
above the woofer. This orientation ensures correct time alignment between the high and low frequencies as they
arrive at the listener.
Horizontal Angle
The speakers should be placed so that they create a 60 degree angle between the speakers, as shown in Figure
5. The easiest way to accomplish this without measuring the angle, is to create an equilateral triangle between the
speakers and the listener. In other words, the distance between each speaker should equal the distance from
each speaker to the listener. The LYD 48 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 speaker.
An easy method to do this involves the tape measure and string.
1. With the tape measure, check to see that the speakers are not placed further away than 2 meters for the best response.
2. Once you have initially placed the speakers, take the string holding one end at the speaker’s acoustic axis and stretch it
out to the listening position.
3. Mark this point with a marker.
4. Do this again for the other speaker to ensure that they are both the exact same distance from the listener.
5. Use the string to measure the distance between each speaker. This should also be the same, forming and equilateral
triangle between the two speakers and the listener.
6. Make adjustments as necessary to place the listener and speakers at the same distance from each other
Vertical Angle
The vertical angle of the speakers should orient the loudspeaker directly toward the listener’s ear level. If the
speaker is placed higher than the listener, they should be angled downward. Conversely, if the speaker is below
the listener’s ear level, they can be angled upward to point at the ear as shown in Figure 6.
