In a listening room, the placement of the speaker and listening position is essential.
In an ideal closed listening room, an A=B=C ratio is chosen. This means that you create an equilateral triangle with the speakers and the listening position.
Place your speakers at a distance of 50-100 cm from the wall.
Due to resonances, the output (strong or weak) of low frequency varies in a room. This has to do with the wavelength and size of a listening room. In short, in an ideal situation, we use as a general rule that your listening position is at 38% in the length of the room. In practice, this can sometimes be from the rear wall.
Of course, you can deviate slightly from the 38% rule. You must avoid a position on 25% or 50% of the space.
In listening rooms, absorption often alternates with diffusion elements. More diffusion of sound, with the help of diffusers, ensures better distribution of sound energy. Diffusers will give you more spaciousness in your room.
Diffusers are placed on the sidewall in our example. In practice, the rear wall or ceiling may also be suitable. Especially with a ceiling that is low, or when you are seated near the rear wall.
