I want to get some nicer speakers, which I could use for my laptop. As with most laptops, I do not have a 7.1 channel sound card, like I do on my main PC. It only sports one sound plug and one for mic. So my question is, what is the "highest" level of a speaker system that I could get? I used to have a 2.1 system but I already forgot... do 2.1 speakers have only 1 plug? Or 2, with a separate one for the subwoofer? Or does it vary?? I used to own a 2.1 but I don't remember for sure anymore lol. Anything higher than 2.1 will definitely not work, right? 5.1 definitely has like 4 plugs.
