Behind. It is recommended to install subwoofers with a rear bass reflex so that the back of the case, where the bass reflex is located, is away from the wall. If you put such a subwoofer right next to the wall, then the sound quality will be noticeably reduced. Bass reflex subwoofers on the back of the cabinet are usually placed in the centre of the room. If it is not possible to put acoustics in the centre, then they try to place this type of subwoofers away from the wall that the bass reflex is looking at.

Front. Front-facing bass reflex subwoofers are good if the acoustics need to deeply reveal the image of low-frequency sound. Acoustics of this type are recommended for music in which there is a lot of bass. The front location of the phase inverter allows you to put the subwoofer almost close to the wall.

From below. Bass reflex subwoofers are designed to be hung at a height. In this case, there will be no interference in the path of low-frequency sound, that is, the bass will be revealed as fully as possible. If it is not possible to hang such a subwoofer, then it is permissible to put the acoustics on a high stand. But the stand should not overlap the phase inverter.

Sideways. Subwoofers with a side bass reflex can be placed close to the wall and in the corner, but if the corn
...er wall does not block the bass reflex. The lateral location of the phase inverter allows acoustics to focus on mid-frequency and high-frequency sound. The low frequency sound will become moderate. This is the optimal acoustic scheme for watching movies.
