Harmon Kardon isub The work quite well and plug in via USB or mini plug (depending on the model) and you can find them on ebay reasonably or buy them new. The only drawback I have found is there is a limit to how loud you can get them to be. Quite adequate for a computer though and works as a stereo in a medium sized room for background music. If you want more plug into your real stereo auxilary and boost the noise as per your stereo wattage. There are many small sub and speaker sets for sale out there. jj On 6-Jun-05, at 2:35 PM, g4-request at listserver.themacintoshguy.com wrote: > Digital Audio > To: g4 at listserver.themacintoshguy.com > Message-ID: <20050606181146.75265.qmail at web32913.mail.mud.yahoo.com> > Content-Type: text/plain; charset="iso-8859-1" > > I recently bought a five slot G4 Powermac.
