2.1 sound out of G4 Mini

2.1 systems are baiscally stereo anyway. They just use a subwoofer (mono) and stereo left and right. The subwoofer channel is derived from the stereo mix. So a set of Harman Kardon Sound Sticks for example would work perfectly fine with a mini or any other stereo device (iPod etc) for that matter.

 

mine works fine as 2.1

in fact for more complete coverage of my living space, i use a splitter and 2 inexpensive but good 2.1 systems--works great

 

should b fine

 

Any regular stereo-out will do 2.1, your Mac mini is no different. It's only 5.1 and upwards that needs special equipment to split the signal into the appropriate areas around the room. 2.1 is just regular stereo with the sub using a mix of the low registers from both right and left signals.

Summary - it's gonna work just fine.
