5. Setup
5.1 Placement
Proper placement is crucial for optimal sound reproduction. Consider the following guidelines:
- Stereo Imaging: Position the monitors to form an equilateral triangle with your listening position.
- Distance from Walls: Avoid placing monitors directly against walls or in corners, as this can exaggerate bass frequencies. Utilize the Room Compensation EQ on the rear panel to adjust for room acoustics.
- Height: The tweeters should ideally be at ear level when you are in your primary listening position.
