5. Installation
5.1 Placement
Optimal placement is crucial for achieving the best sound performance from your Theva N°3-D loudspeakers, especially for Dolby Atmos effects.
- Configuration stéréo : 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.
- Distance des murs : Experiment with the distance from the rear and side walls. Placing speakers too close to walls can overemphasize bass, while too far can reduce bass impact. A good starting point is 1-2 feet (30-60 cm) from the rear wall.

- Type de terminal: The Theva N°3-D features binding posts that accept bare wire, spade connectors, or banana plugs.
- AmpChaînes lifier : Connect the main speaker terminals to the front left and right channels of your amplifier.
