The operations manual for the Jupiter specifies a 4 Ohm speaker should be
used for external sound. As you know the audio output comes from a
transistor amplifier. In this type of audio amplifier it is important to
match the speaker impedance to the output impedance. If it is not
matched,inefficiency and distortion can occur especially at high volume
levels, and the amp has only 1 watt to begin with.
