Home theater includes a whole complex of equipment, which consists of an acoustic system, a multichannel amplifier, a
receiver and a video / audio signal source. Usually the kit does not include a playback device, so the TV or
projector must be purchased separately. Particular attention should be paid to the speaker system, because it is the sound format that can give the desired depth and liveliness to the sound.

  5. The sensitivity parameter is responsible for the volume of the speakers, which is equal to the amperage exiting the amplifier. Simply put, the higher the sensitivity, the louder the final sound.
  6. Arrangement of the speaker system . Some home theaters require non-standard placement of playback devices, this is due to the peculiarities of specific models. This factor should be taken into account, otherwise an unpleasant situation may arise, for example, there is not enough space in the room, therefore it will not be possible to fully unleash the potential of a home theater.
