Short answer: the KEF Q Concerto Meta. It ranks #11 of 222 bookshelf speakers by sound quality, rated 4.6/5, at $999.99; the JTR Speakers Noesis 210HT ranks #43, rated 4.3/5, and costs $3,998, which makes this an easy call rather than a real tradeoff.
The KEF Q Concerto Meta is the more accurate, deeper-bass 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 2.66 for the JTR Speakers Noesis 210HT. Its bass reaches about 53Hz before falling 3dB, against 76Hz for the JTR Speakers Noesis 210HT. The catch: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment.
What the JTR Speakers Noesis 210HT does well: A very high output home theater speaker with dual 10 inch woofers and a coaxial horn, easy to drive and built for reference level movies. The catch: Erin measured F3 at 76Hz and F10 at 43Hz, so the 210HT is designed to hand bass duties to subwoofers rather than operate full-range.
Buy the KEF Q Concerto Meta. It is rated higher for sound quality than the JTR Speakers Noesis 210HT and costs less, which makes it the one to get unless you need something the other one does better.
