A lot of sound quality on tiny speakers these days comes from equalizing or otherwise processing the audio signal. I do not know how you would do this on Windows, but I’m sure there are tools to achieve things similar to this: http://community.frame.work/t/guide-framework-dsp-better-linux-audio/44645/1
The result is quite impressive for me. I thought the speakers were nice enough, but this makes them sound a good bit better and there is probably more to do if one wants to tinker.
