Calculadora de Disposición de Altavoces de Techo Dolby Atmos

Calcule las coordenadas de los altavoces cenitales de dos o cuatro canales a partir de la altura del techo, la altura del oído y el ángulo de elevación.

The plan is centred on the main listening position. Four-channel layouts place one pair forward and one pair behind; two-channel layouts place a single pair overhead.

Cómo funciona

How to use it: select two or four overheads, then enter the ear-to-ceiling geometry and preferred elevation angle.

Formula. Horizontal offset = (ceiling height - ear height) / tan(elevation angle).

Example. With a 1.65 m vertical rise and 45-degree elevation, each four-channel row is 1.65 m forward or behind the listener.

Antes de usar el resultado

  • 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.

Limitaciones

This is centre-line geometry for a two- or four-overhead starting layout, not certification. Joists, angled ceilings, multiple rows and speaker dispersion can require different positions. Check the official Dolby speaker setup guide for your exact channel layout before installation.

Preguntas frecuentes

Can two overhead speakers go directly above the seat?

This planner centres a two-channel pair over the listening position. Speaker documentation may recommend a small forward offset depending on the system and room.
