Studio monitor placement

Symmetry reduces channel differences. The 38% rule and equilateral triangle are starting points that require measurement-based fine tuning.

Key principle

Do not optimise one number at the expense of the full spectrum and room purpose.

Step-by-step process

  1. Define the room purpose.
  2. Record dimensions and hard surfaces.
  3. Run a baseline estimate.
  4. Introduce a minimal treatment variant.
  5. Measure, compare and refine.

Decision example

If mid-band RT60 is high but bass remains uneven, more thin panels may improve speech without solving boom. The next step is mode and position analysis.

Example

Example: a 4.2 × 3.4 × 2.6 m room with hard walls and partial panel coverage. Change one parameter at a time and compare saved variants.

Limitations

The result is a first-order model. Real reflections depend on geometry, furniture, gaps, mounting and the positions of the source and microphone.

FAQ

Does this replace a measurement?

No. It helps plan an initial variant and budget, but final decisions should be verified with an impulse-response measurement.

Are more panels always better?

No. One-sided absorption can leave bass problems unresolved and make the upper range too dry.
