Short answer: the KEF R3 Meta. It ranks #10 of 222 bookshelf speakers by sound quality, rated 4.6/5, at $2,499.99; 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 R3 Meta is the more accurate choice. A three way bookshelf speaker with KEF’s coaxial driver, superb accuracy that holds across the room, and bass that reaches deep for its size. Its measured preference score, a predictor of how neutral it sounds, is 6.10 against 2.66 for the JTR Speakers Noesis 210HT. The tradeoff: Pointed straight on-axis, there’s a 1-2dB bump around 9kHz that stays consistent across angles thanks to the constant-directivity waveguide: only toeing the speaker out about 10° tames it.
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. Watch for: 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 R3 Meta. It is rated higher for sound quality than the JTR Speakers Noesis 210HT and costs less, so only choose the other one for a particular feature it does better.
