The speaker placement calculator recommends listening position, speaker angles, and wall distances for stereo and surround sound setups based on your room dimensions.
Room & Speaker Setup
Optimal Speaker Placement Principles
Speaker placement dramatically affects the quality of your listening experience. Poor placement causes cancellations, bass buildup, and uneven soundstage. A few simple rules make a large improvement even in imperfect rooms.
The Equilateral Triangle (Stereo)
The classic stereo setup places both speakers equidistant from the listening position, with 60° between them. For a 12-foot wide room, speakers go about 6-8 feet apart and the listening position 6-8 feet back. Tow the speakers in slightly toward the listening position for a focused center image. Avoid placing speakers symmetrically with their back against a wall — pull them 2-3 feet out to reduce bass reinforcement.
5.1 Surround Setup
Front L/R follow the same equilateral triangle rule. The center channel sits on or near the display. Surround speakers go to the sides at about 90-110° from the listening position, slightly above ear height. The subwoofer is most flexible — start near the front wall between the main speakers and adjust by ear for even bass response.

What is the equilateral triangle rule for stereo speakers?
For stereo listening, place speakers at 60° apart with the listener at the apex of an equilateral triangle. This means the distance between speakers equals the distance from each speaker to the listening position. With speakers 6 feet apart, the listener should sit 6 feet back from the midpoint between them.
How far from the wall should I place speakers?
Speakers near walls experience bass reinforcement due to boundary effects. Generally, place speakers at least 2-3 feet from the front wall (behind the speakers) and 2+ feet from side walls. For bookshelf speakers with a rear port, 1-2 feet of clearance helps. Trial and error with subwoofer placement is often needed to minimize bass room modes.
Where should the subwoofer go in a 5.1 system?
Start with the subwoofer at your listening position, then play bass-heavy music and walk around the room to find where bass sounds most even. That location is where you place the sub. Common placements: along the front wall between the two main speakers, or in a corner for maximum output (but corners can cause boomy bass).
How high should surround speakers be?
For 5.1 surround, rear/side speakers should be at ear height or slightly above (2-3 feet above ear level) when seated. Atmos overhead speakers go in the ceiling or are aimed upward from atop the main speakers. The goal is to create sound that comes from the correct position in the soundfield.
