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 Buchardt Audio E50 ranks #16, rated 4.5/5, and costs $4,600, so there is not much of a tradeoff to weigh.
The case for the KEF Q Concerto Meta: A neutral three way bookshelf speaker that sounds consistent from seat to seat, with smooth treble that many rivals at its price lack. The tradeoff: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment.
The Buchardt Audio E50 is the deeper-bass option. A bookshelf speaker with remarkably deep bass for its size, a very neutral midrange, and low distortion, with no need to sit near a wall. Its bass reaches about 40Hz before falling 3dB, against 53Hz for the KEF Q Concerto Meta. Watch for: A roughly 3dB dip in the upper midrange/lower treble softens attack and dialogue clarity: the reviewer’s main complaint, and it’s baked into the crossover rather than a directivity artifact, so it’s audible both on and off axis.
Buy the KEF Q Concerto Meta. It is rated higher for sound quality than the Buchardt Audio E50 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
