4. Setup
4.1. Placement
Proper placement of your JBL 305PMkII monitors is crucial for accurate sound reproduction. Position the monitors to form an equilateral triangle with your listening position, with the tweeters at ear level. The Image Control Waveguide ensures a wide sweet spot, but optimal positioning enhances detail and stereo imaging.
- Place monitors on a stable surface, ideally on isolation pads (included) to minimize vibrations.
- Maintain a distance from walls and corners to reduce bass buildup. If placement near boundaries is unavoidable, use the Boundary EQ switch on the rear panel.
