Usually, the enclosure shape for loudspeaker cabinets is only chosen considering the avoidance of standing waves and edge diffraction effects. Investigations of very flat enclosures, however, have shown influences on the vibration behavior of electrodynamic transducers built in such enclosures. The smaller the enclosure depth at the same volume size, the more the resonance frequency and the diaphragm excursion differ from transducers built in "normal" shaped enclosures. Based on this observations further investigations were performed to examine their consequences on the acoustical behavior. In this paper acoustical measurements are presented revealing interesting effects on the distortion behavior.
