The right Hi-Fi gear can work very well in small rooms. The biggest challenge you face is the closeness of your seating position to the speakers. Hi-Fi speakers need more space between you and them ato develop decent soundstage. PC speakers and nearfield monitors are designed for listening at a desktop or mixing desk, but that doesn't make them particularly useful as conventional Hi-Fi speakers.
The only crossover product I'm aware of that delivers Hi-Fi performance on a desktop is the Focal XS. The issue though is that the feed is via USB and line level. That rules out using them with a traditional Hi-Fi amp.
