Stereo 2.1 question

Hi , when I install k lite mega there is an option to choose type of my speakers ....well , I have stereo 2.1 with subwoofer and when I choose it (2.1) there is a massage popup to tell me there are real 2.1 stereo and fake .
How could I identify the real one from fake besides both of them have 2 speakers and subwoofer .

If the speaker set is connected using just 1 cable, then choose 2.0. If each speaker has its own cable connected to your computer, then choose 2.1.

Thank you for reply ' I have one cable connected between pc and subwoofer ' from subwoofer there are two cable out to each speaker .Did that means a 2 (non 2.1). That is quastion number 1 .
Number 2 is my friend have Creative A300 speakers , What type of it 2 or 2.1 .?
I am so appreciate for answer
With thanks

A single cable to the PC, so 2.0 is correct. The speakers themselves are of course always interconnected in this case.

It is a 2.1 speaker set. However it only uses 2.0 as input. The subwoofer uses the low-frequency information from the stereo channels.

Even if you would set 2.1 in the codec pack, Windows would convert it to 2.0.

Thank you so much ....I am appreciate for that ....and you right when I choose 2.1 it's returned to 2 .
Can you mention a real 2.1 model speakers like creative , logitech, asus ....with model number .
I would be thankful

You already have a 'real' 2.1 set. It simply just takes normal stereo as input. The information that the subwoofer uses is mixed into the stereo channels. You are not missing anything.

If you want to have more bass, then there are several ways to achieve that.

Thanks so much
