You don’t specify your price range, which will factor in your choices.
Back in 2004 (?!!), I bought a Logitech® Z-5500 system, which has 5 fairly small speakers and a subwoofer, connects to my Mac(s) via optical digital, and importantly for me, has a physical knob that sits on my desk to control sound and settings (it also has a remote, fwiw). I paid a couple hundred dollars, money well spent. It looks like there is a newer version of this setup, per Amazon, " Logitech Z906 5.1 Surround Sound Speaker System - THX, Dolby Digital and DTS Digital Certified” for $300. This could be overkill for you though. The system is almost overkill for me, I rarely turn the volume up lest my neighbors complain, but the sound is great.
Since my ears are not “concert quality”, I simply have a speaker on either side of my desk, two more on the top shelf of my desk, and one sitting over by my office couch, plus the subwoofer next to my MacPro…
