Stereo or 2.1?
Stereo speakers are ones that only have a left and a right speaker.
2.1 speakers have two speakers as well as a subwoofer. It’s the job of the subwoofer to pick up lower-frequency sounds (bass). A high-quality subwoofer can add great value to your listening experience as it can add depth and richness to bass guitars and drums in songs, etc.
Most of the speakers that people purchase for computers come in stereo pairs. They sometimes have accompanying subwoofers but not every time.
We would recommend that you get speakers with a subwoofer if you have the space for it and if you can afford it.
Price
The price of a speaker is definitely something to think about but you don’t want to go so low that you end up buying speakers that produce low-quality sound and will break down within a few months.
Thus, you have to strike a balance between the price and the quality of the speakers.
Weight and Size
Since these speakers are going to be on your computer desk, it’s important that they don’t take up too much space. Take a good look at your desk and determine what type of speakers would be at home on it.
You want speakers that sound good (as heavier, bigger speakers quite commonly sound better than lighter, smaller ones) but are also not too big and obtrusive for your desk.
Design
This has the same logic as that when considering the weight and size of the speakers: Since they’re going to be on your desk, you want them to look presentable and appealing.
Try to go for speakers that match the aesthetic of your computer so that when you add them to your setup, it’ll look like they had always been there.
