Imo the Bose are $10 speakers with a $90 nameplate. Their purpose is to get people to hand over lots of money based on a well-marketed brand name.
Imo 4.1 and 5.1 sets with tiny little 2 or 3 inch speaker cones are very range limited, audio-wise. Their purpose is for surround-sound gaming at a limited budget.
Even in my very small city, the local scrap shops have no shortage of old small-bookshelf speakers (15 to 25cm high) from fair quality Japanese brands like Sony, Panasonic, Akai, Sanyo et al which are perfectly retro (from the same eras as our computers) and are sonically far superior to 99% of the "specifically PC oriented speakers" market segment.
I got Made-in-Japan mag-shielded Sony's (made of wood, + 5" cones, + tweeters) for $10. Add "some form of amplification". That's about all it takes to exceed Mr Lucky LGR's Rare Rolands (which, once the glamour is all stripped away, are basically 4" cones inside plastic boxes) in sheer quality of audio experience, in a still-desktop-friendly format. But nowhere near as trendy.
So, PC speaker choice depends upon balancing out what's important to you personally in this. Brand name? Surround channels? Audio range? Cool factor? Convenience of purchase? Physical size?
That's how I do it. It looks plain but, for a old PC, sounds f'ing amazing.
