Optimal placement is crucial for achieving the best sound performance from your Theva N°3-D loudspeakers, especially for Dolby Atmos effects.
- Sazkirina Stereo: For a traditional stereo setup, place the loudspeakers equidistant from your primary listening position, forming an equilateral triangle.
- Home Cinema Setup: In a home cinema configuration, the Theva N°3-D speakers should be positioned as your front left and right channels. Ensure they are placed symmetrically relative to your screen and listening area.
- Dolby Atmos: The integrated upward-firing driver requires a reflective ceiling. Position the speakers so that the sound from the top driver can reflect off the ceiling and reach your listening position. Avoid placing them under sound-absorbing materials or very high ceilings that might diminish the effect.
