The sound system further comprises a low-frequency loudspeaker and a hermetically sealed enclosure with two openings, through one of which the loudspeaker is acoustically coupled to the enclosure and through the other the enclosure is acoustically coupled to the opening of the tube-like cavity; where the hole in the wall has a size and a position such that a resonance of the sound system deteriorating its sound quality is reduced.
