Used Canton GL 260. Recap them with good caps. Still way better than most of the new bookshelf/desktop speakers.
Best Desktop Speakers under $500
Will be used mostly for listening to music/podcasts while I work. I will not be getting a sub right now since I'm in an apartment so that is something to keep in mind.
I enjoy nice aesthetics so if they look nice or come in a color other than black, that is a plus for me.
