A speaker system comprises a main cabinet and two auxiliary speakers. The main cabinet encloses a bass speaker and includes a slot for slot-loading of the bass speaker. The auxiliary speakers have a frequency range higher than that of the bass speaker, and are in enclosures which fit within slots in the main cabinet. The system provides a high-quality speaker system which is easily transported by placing of the auxiliary speaker in a slot.
