Short answer: the Buchardt Audio E50 for better sound quality, the KEF Q3 Meta for the lower price. The Buchardt Audio E50 ranks #16 of 222 bookshelf speakers, rated 4.5/5, at $4,600. The KEF Q3 Meta ranks #156, rated 3.4/5, at $764.97, $3,835.03 cheaper.
Why pick the KEF Q3 Meta: Coaxial bookshelf speakers with very wide dispersion, punchy kick drums and bass tuning that works close to a wall. Watch for: Not well suited to high-output use: compression and strain in the 1-2kHz region emerge above about 90dB at 10 feet, so a high-output home theater setup isn’t the best application.
The Buchardt Audio E50 is the more accurate, 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 measured preference score, a predictor of how neutral it sounds, is 5.84 against 4.66 for the KEF Q3 Meta. Its bass reaches about 40Hz before falling 3dB, against 52Hz for the KEF Q3 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 Q3 Meta if the price is the priority over sound quality, or the Buchardt Audio E50 if sound quality is the priority over the price.
