I literally never heard a single set of computer speakers in the 90s that impressed me.
I also haven't heard any since, including Klipsch Promedia THX which other people loved (for some reason) say 10-15 years ago, and some still do.
I don't say these things to troll the thread or anything but I guess my point is that it really depends on your expectations. It's a difficult question to ask if a pair of inexpensive speakers sound good. In any measurable way (frequency response, harmonic distortion, cumulative spectral decay, etc.) they will be awful and I can guarantee that 100%. But I cannot guarantee even 1% that YOU will think they're awful, especially if you're feeling nostalgia for the sound that speakers like that make.
If you want vintage speakers, Altec Lansing is a good way to go. If you want good speakers, use real passive non-PC-specific speakers and either a small Tripath-based amp or an actual stereo or multichannel receiver. If you want good, vintage speakers, use vintage real, passive, non-PC-specific speakers with an old Pioneer or Technics or Yamaha stereo receiver (aka integrated amp)... in my opinion.
I pretty much always had my computers hooked up to a real receiver with tower speakers (through the 90s this setup for me was all Technics). It might not be the retro audio gear that retro gamers think of but you can get genuine retro audio gear and still appreciate it. Again, depends on your expectations.
Heck, I'd sooner design my own custom speakers in those cases with different drivers (in this context a "driver" is like saying "an individual speaker that is part of a speaker system"), but I'm pretty crazy (not necessarily in a good way, either) about audio quality. I don't expect you to be similarly crazy or you probably wouldn't ask about these speakers at all, but I like talking about multiple options.
I have edited this like 5 times to ramble more. Geez.
Yes, I always ramble this much.
