Abstract
A loudspeaker system is described that includes a loudspeaker and an extender. The loudspeaker can be positioned on the ground and the extender can be optionally connected thereto. When the extender is connected to the loudspeaker, the loudspeaker is capable of selectively sending high-frequency components of an input audio signal to the extender and the extender is capable of playing back such high-frequency components to produce high-frequency audio. Due to the fact that an audio-producing apparatus of the extender can be positioned at a higher elevation than the loudspeaker, the high-frequency audio (which is more directional than lower-frequency audio) can be produced at a height that is likely to match that of the ear height of a user as opposed to producing the audio at floor height.
