Short answer: the KEF Q Concerto Meta. It ranks #11 of 222 bookshelf speakers by sound quality, rated 4.6/5, at $1,399.99. The ELAC Uni-Fi Reference UBR62 ranks #65, rated 4.1/5, at $1,299, $100.99 cheaper, not enough of a saving to outweigh the sound-quality gap.
The KEF Q Concerto Meta is the more accurate pick. 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 5.44 for the ELAC Uni-Fi Reference UBR62. The tradeoff: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment.
The case for the ELAC Uni-Fi Reference UBR62: A three way bookshelf speaker with a coaxial tweeter and midrange for stable imaging, well controlled tonality, and front ports for easy placement. The catch: Erin measured very low 83dB/2.83V/1m sensitivity; his 110W Parasound was insufficient for the high-level test and the more powerful HINT 6 was needed.
Buy the KEF Q Concerto Meta. It is rated higher for sound quality, and the $100.99 saving on the ELAC Uni-Fi Reference UBR62 is not enough to make up the difference.
