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 Danley SH50 ranks #54, rated 4.2/5, and costs $8,000, so there is not much of a tradeoff to weigh.
The KEF Q Concerto Meta is the more accurate, deeper-bass choice. 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 -0.29 for the Danley SH50. Its bass reaches about 53Hz before falling 3dB, against 60Hz for the Danley SH50. The catch: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment.
The case for the Danley SH50: A massive pro grade point source speaker with a single horn, extraordinary output, and tightly controlled sound for large rooms and venues. The tradeoff: This 133-pound, roughly 28-inch cube is engineered for venues and large rooms, not conventional domestic nearfield listening.
Buy the KEF Q Concerto Meta. It is rated higher for sound quality than the Danley SH50 and costs less, so only choose the other one for a particular feature it does better.
