Optimal subwoofer placement is crucial for achieving the best bass performance in your listening environment. Experiment with different locations to find the ideal spot. Generally, placing the subwoofer in a corner can enhance bass output, while placing it along a wall can provide a more balanced sound. Avoid placing it directly in the center of a room, which can sometimes lead to bass nulls.
