Thats a 'line level mixer' circuit for mixing line level signals. If your
speaker is a powered unit (IE It uses a line input and applys it to a power
amp inside the speaker unit) not just a speaker with directly connected
voice coil then that should do it as far as I can see. Also assuming you are
using the line outputs on the computers.

Where theres a will, I want to be in it.

Thank you for reply, Rheilly.
Yes it is an active 2.1 speaker and I'm connecting it to output of
-PC AC'97 soundcard and to
-Amiga sound output.

(both work fine alone with speakers)

I would like to just use that simple circuit with only two 10KOhms
resistors, hope it will do. (don't need mixing stuff)

The circuit on the website you have given, will mix the audio output
from both computers and output them to the same set of speakers.

If this is what you want to do or you will only be outputting audi
from one computer at a time, this should be fine.

Otherwise, you could just use a standard SPDT switch if the signal i
mono (i.e to 1 speaker only) or a DPDT switch if using two speaker
(Stereo).

You could also tie the output of one system to the line-in of the other.

[First system] --out--> in to [second system] --out--> [speaker]
