>> I guess the solution is to buy a surround sound system and hope it's good enough.
This made a huge difference for me. I went from TV > Sonos Beam > Sonos Beam + two surrounds. I've tested going back to just the Beam (I wanted to use the surrounds as stereo music speakers) but the huge decrease in my ability to understand dialog made me keep the surrounds. It's particularly problematic on TV shows where background music is used a lot. Having that come out of the surrounds and dialogue from the Beam made things so much better.
