5. Kukhazikitsa
5.1 Kuyika
Optimal placement is crucial for achieving the best sound performance from your Theva N°3-D loudspeakers, especially for Dolby Atmos effects.
- Kukhazikitsa kwa 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.
- Distance from Walls: 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.

- AmpLifier Channels: Connect the main speaker terminals to the front left and right channels of your amplifier. For the Dolby Atmos effect, ensure your amplifier or AV receiver has dedicated height channels and connect the top-mounted driver terminals to these outputs. Consult your amplifier's manual for specific height channel connections.
