Rechner für Stereo-Lautsprecherplatzierung

How to use it: enter the room and front speaker offset. Adjust the listening position from the rear wall; 38% is a starting point, not a rule.

Method. The calculator targets a 60-degree stereo angle, then limits separation where the room is too narrow.

Example. With a 4.2 by 5.5 m room and a seat 38% from the rear, the listener is 3.41 m from the front wall.

The result above uses these exact values. This snapshot is included when the page is printed so the output can be checked against the original measurements.

Room width

4.2 m

Room length

5.5 m

Listener from rear wall

38 %

Speakers from front wall

0.5 m

Primary result: Speaker separation: 3.36 m.

• Measure from the datum or reference edge described by this tool, and do not mix inside, outside and centerline dimensions.
• Keep inputs in the displayed units and preserve more precision than the final cutting or purchasing tolerance requires.
• When the result is close to a limit, verify it with a test piece, field measurement, manufacturer drawing or qualified project professional.

This is geometric placement, not acoustic optimisation. Furniture, doors, speaker directivity, boundary gain and measured bass response may justify asymmetric or non-equilateral positions.
