Speaker Placement Calculator

Speaker placement has a dramatic effect on sound quality — often more than upgrading equipment. Proper positioning creates a wide, focused stereo image with balanced frequency response.

The stereo triangle: The two speakers and the listening position should form an equilateral triangle. Each side of the triangle should be the same length. The speakers should be angled inward (toed-in) to face the listening position.

Toe-in angle: Typically 15-30 degrees inward. Start with both speakers pointing at a spot about 1-2 feet behind your head and adjust by ear.

Distance from walls:

• Side walls: At least 2 feet (60 cm). The further from side walls, the less comb filtering and reflections.
• Back wall (behind speakers): At least 2-3 feet (60-90 cm). This reduces bass boom and improves midrange clarity.
• Rule of thirds: Place speakers 1/3 of the room length from the front wall for a good starting point.

Listening position:

• Sit at approximately 38% of the room length from the front wall (where speakers are).
• Avoid sitting against the back wall — this exaggerates bass.
• Ears should be at tweeter height.

Room modes (bass peaks and nulls): Bass frequencies create standing waves in rectangular rooms. Sitting at room center or at 50% points along any dimension puts you in a bass null. Sitting at 25% or 75% points along room dimensions often gives more even bass.

Speaker height: Tweeters should be at ear height when seated. If on stands, typical height is 36-40 inches (91-102 cm) to the tweeter. If on a bookshelf or desk, tilt them to aim the tweeter at ear level.

Subwoofer placement: The “subwoofer crawl” method works well: place the sub at your listening position, then crawl around the room perimeter to find where the bass sounds best. Place the sub there.
