Short answer: the Dynaudio Contour 20i on measured sound quality, the Polk Signature Elite ES20 on price. The Dynaudio Contour 20i ranks #96 of 222 bookshelf speakers, rated 3.9/5, at $5,750. The Polk Signature Elite ES20 ranks #119, rated 3.7/5, at $398.98, $5,351.02 cheaper.
What the Polk Signature Elite ES20 does well: Large, efficient bookshelf speakers with unusually deep bass for the price and wide horizontal coverage. Watch for: Predicted in-room smoothness of 0.238 and directivity-index consistency of 3.81 are average rather than class-leading.
Why pick the Dynaudio Contour 20i: Beautifully built bookshelf speakers with wide, spacious sound, clean output at high volume, and bass that blends easily near a wall. Watch for: Notably room-dependent: sounds too bright in the lower treble in smaller rooms with close sidewalls, needing sidewall absorption to sound neutral, while performing better in larger or more open rooms without that treatment.
