Short answer: the KEF Q Concerto Meta for better sound quality, the KEF Q350 for the lower price. The KEF Q Concerto Meta ranks #11 of 125 bookshelf speakers at $1399.99. The KEF Q350 ranks #101 at $699, $700.99 cheaper.
What the KEF Q Concerto Meta offers: Really good in-room neutrality with consistent horizontal directivity from seat to seat. Directivity holds remarkably steady from lower treble into upper treble, where many similarly-priced speakers narrow sharply as frequency rises - one of the reviewer’s top 10 picks under $1,500. Watch for: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment. Needs to be pointed closer to on-axis rather than heavily toed out - combined with its rolled-off, shelved-down top end, too much toe-out makes it sound noticeably dark.
What the KEF Q350 offers: CEA2034 spinorama shows a reasonably flat on-axis response with excellent directivity, aided by the coaxial Uni-Q driver. Vertical directivity is better than most non-coaxial two-way speakers, another benefit of the concentric design. Watch for: Two resonances at 700Hz and 1.2kHz show up on-axis, alongside an upper-bass boost. Predicted in-room response looks a bit boomy as a result. Distortion climbs substantially in the 100Hz-1kHz range at 96dB SPL/1m, with a distinct resonance-driven peak around 900Hz-1kHz at both test levels.
Buy the KEF Q Concerto Meta if sound quality matters more than the price. Buy the KEF Q350 if the price matters more than sound quality.
If sound quality matters at all to you, skip the KEF Q350. It ranks near the bottom of the 125 bookshelf speakers, so look higher up the list instead.
