Polk TSx220B vs Polk Es20

Options
Hi everyone!
I'm using the Polk TSx220B combined with a Klipsch Sub10 for many years and generally I like the sound. But I think the mids and heights could be a bit more refined, especially when it comes to movies.
Since I've found a good deal for a pair of Polk Es20 speakers here in Germany I'm wondering if those could be a good upgrade over the TSx220B.
What do you guys think?
