How to Use the Speaker Distance Calculator
Enter how far you sit from your stereo speakers to get a recommended speaker placement using the equilateral triangle rule — a widely used starting point for stereo imaging. In this setup, the distance between the two speakers is made equal to the distance from each speaker to the listening position, forming a triangle with three equal sides so both speakers arrive at the listening spot with balanced timing and volume.
Recommended Toe-In Angle ≈ 30° inward
Example
If you sit 8 feet from where your speakers will be, place the speakers 8 feet apart from each other as well, forming an equilateral triangle with your listening position. Angle each speaker inward by roughly 30° so they both point toward the listening spot.
Common Use Cases
- Setting up a new pair of stereo speakers in a living room or home studio.
- Repositioning speakers after rearranging furniture or moving to a new room.
- Getting a solid starting point before fine-tuning placement by ear.
FAQs
- Is the equilateral triangle rule a strict requirement? No — it's a well-established starting guideline, not a strict rule. Room acoustics, furniture, wall reflections, and speaker design all affect the ideal placement, so treat this as a solid baseline to fine-tune from by ear.
- Why angle the speakers inward at all? Toe-in aims each speaker's most direct, focused sound at the listening position rather than letting it fire straight ahead past the listener, which typically sharpens stereo imaging and center-channel focus for near-field and mid-field listening distances.
- Does this work for all room sizes? The equilateral triangle scales with any listening distance, but very small rooms may need to compromise on exact spacing due to walls and furniture, and very large rooms may benefit from slightly wider spacing than a strict equilateral triangle to fill the space.
