A system for controlling speaker apparatus comprising:

• a main speaker apparatus having a plurality of communication circuits;
• a controller configured to wirelessly connect with the main speaker apparatus by a first connection method;
• and one or more secondary speaker apparatus configured to wirelessly connect with the main speaker apparatus by a second connection method, wherein the first connection method is different from the second connection method, the main speaker apparatus includes a storage unit configured to store speaker apparatus information relating to the one or more secondary speaker apparatus to which the main speaker transmits a signal by the second connection method, the controller has a display unit and an acquisition unit configured to acquire the speaker apparatus information from the main speaker apparatus by the first connection method when the controller commands the main speaker apparatus to turn on a communication circuit for the second connection method in response to a user input, the controller determines if a received speaker apparatus information includes the information representing the one or more secondary speaker apparatus, and if the speaker apparatus information includes the information representing the one or more secondary speaker apparatus, the display unit displays information representing the one or more secondary speaker apparatus based on the speaker apparatus information stored in the storage unit, if the speaker apparatus information does not include the information representing the one or more secondary speaker apparatus, the controller causes the main speaker apparatus to search for the one or more secondary speaker apparatus, and the display unit displays the information representing the one or more secondary speaker apparatus based on the search.
