How It Works

The 38% rule places your listening position at 38% of the room length from the front wall, which avoids the worst room mode nulls. Speakers form an equilateral triangle with the listening position at a 60° spread angle. Key rules: keep speakers at least 0.6m from side walls, keep the listening position away from the exact room center (worst bass null), and angle tweeters toward your ears. The tweeter height should match your seated ear height (~1.2m).
