Short answer: the AsciLab F6B. Both are rated 4.6/5 for sound quality (#12 and #11 of 222 bookshelf speakers), and the AsciLab F6B costs $980 against $999.99 for the KEF Q Concerto Meta, and with sound quality even, the cheaper one is the better buy.
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. Watch for: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment.
What the AsciLab F6B does well: A great value bookshelf speaker with accurate, well balanced sound and punchy midbass that gives kick drums extra impact. Watch for: A mild sibilance-inducing lift around 6-8kHz, most noticeable on female vocals, paired with a shallow dip in the upper midrange: correctable with a simple 3-band EQ the reviewer provided.
Buy the AsciLab F6B. Both are rated the same for sound quality, and it costs $19.99 less than the KEF Q Concerto Meta.
