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 130 bookshelf speakers at $1399.99. The Polk Signature Elite ES20 ranks #69 at $359, $1040.99 cheaper.

KEF Q Concerto Meta vs Polk Signature Elite ES20

What the KEF Q Concerto Meta offers: Really good in-room neutrality with consistent horizontal directivity from seat to seat. Directivity holds remarkably steady from lower treble into upper treble, where many similarly-priced speakers narrow sharply as frequency rises - one of the reviewer’s top 10 picks under $1,500. Watch for: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment. Needs to be pointed closer to on-axis rather than heavily toed out - combined with its rolled-off, shelved-down top end, too much toe-out makes it sound noticeably dark.

What the Polk Signature Elite ES20 offers: A full-size, efficient 6.5-inch bookshelf pair with unusually deep bass for the price. ASR measured 41Hz estimated in-room extension, a well-damped Q of 0.66, broad horizontal coverage to roughly +/-60 degrees and a 5.54 preference score with a subwoofer. Watch for: Predicted in-room smoothness of 0.238 and directivity-index consistency of 3.81 are average rather than class-leading. The deep cabinet needs substantial shelf or stand space, and its Power Port still requires rear clearance.

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.
