A:Answer George, I was going to give you a smart a-- answer to read the manual, until I read mine. I don't know why manufacturers don't show pictures of the ports, front and back but for some reason they don't seem to.
The answer to your question is:
Key Audio/Peripheral Details:
Rear Ports: 3x 3.5 mm audio jacks (input, output, microphone).
Front Ports: 1x headphone/microphone combo.
I have my speakers (mid-level computer speakers with a sub-woofer) connected through these rear ports and it works fine.
I found that you can also connect USB speakers to any of the 3 USB A 2.0 ports on the back of the computer as well.
Sorry you had to ask.
