Short answer: the KEF Q Concerto Meta if sound quality matters most, the Polk Signature Elite ES20 if price matters most. The KEF Q Concerto Meta ranks #11 of 222 bookshelf speakers, rated 4.6/5, at $1,399.99. The Polk Signature Elite ES20 ranks #119, rated 3.7/5, at $398.98, $1,001.01 cheaper.
The KEF Q Concerto Meta is the more accurate option. A neutral three way bookshelf speaker that sounds consistent from seat to seat, with smooth treble that many rivals at its price lack. Its measured preference score, a predictor of how neutral it sounds, is 6.01 against 4.49 for the Polk Signature Elite ES20. The tradeoff: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment.
Why pick the Polk Signature Elite ES20: Large, efficient bookshelf speakers with unusually deep bass for the price and wide horizontal coverage. The catch: Predicted in-room smoothness of 0.238 and directivity-index consistency of 3.81 are average rather than class-leading.
Buy the KEF Q Concerto Meta if sound quality is the priority over the price, or the Polk Signature Elite ES20 if the price is the priority over sound quality.
