I have an awesome computer with awesome sound card and a big 4k tv as a second monitor on which I watch a lot of movies. I want the best speakers I can buy for up to $400. Thanks for your input!
The Rokit5 (and previous) speakers have been one of the most popular catch-all anwers to this for several years now. Doing a quick search popped up the review I've linked below suggesting that the Yamaha HS5 speakers have an even better sound though.
