Short answer: the Polk Signature Elite ES20. It ranks #119 of 222 bookshelf speakers by sound quality, rated 3.7/5, at $398.98; the Triangle Borea BR03 ranks #198, rated 2.8/5, and costs $399, which makes this an easy call rather than a real tradeoff.
Why pick the Triangle Borea BR03: A budget French bookshelf speaker with dual front ports, decent bass for the price and solid, well braced build quality. The catch: A noticeable mid-range suckout, most pronounced in the upper mid-range/lower treble, that the reviewer attributes to cabinet resonances and driver breakup rather than a deliberate voicing choice: it makes vocals and instruments sound recessed and thin rather than warm.
The Polk Signature Elite ES20 is the better-sounding pick. Large, efficient bookshelf speakers with unusually deep bass for the price and wide horizontal coverage. The tradeoff: Predicted in-room smoothness of 0.238 and directivity-index consistency of 3.81 are average rather than class-leading.
Buy the Polk Signature Elite ES20. It is rated higher for sound quality than the Triangle Borea BR03 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
