[TenTec] Ten-Tec External Speaker

[Bill Ames]

I think that TT will provide a speaker that meets the interface requirements
for the Jupiter but I am concerned that it will not be as good as it could
be because, I believe, you get better sound from speakers that are less
efficient and require some power to get the best results. Since the J has
limited audio output power it can not drive these less efficient speakers. I
do not see them adding any electronics to the new speakers, so, I am
prepared to be somewhat disappointed...

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.
