Short answer: the KEF Q Concerto Meta is a major engineering step up from the older Q350, with deeper bass and better-controlled in-room response. Concerto Meta uses a dedicated 6.5-inch woofer plus a 4-inch midrange and MAT-equipped tweeter, reaching 53Hz at -3dB. The Q350’s single Uni-Q driver reaches only 70Hz at -3dB. The KEF Q350 is discontinued; its replacement is the KEF Q3 Meta, rated 3.4/5.
Q350 retains the coaxial platform’s good directivity and vertical behavior, but it has measured resonances at 700Hz and 1.2kHz, an upper-bass lift, and rising distortion. Concerto Meta is narrower than some listeners may prefer and should be aimed more directly toward the seat, but its smooth, consistent directivity makes that setup worthwhile.
Buy the KEF Q Concerto Meta for more full-range bass, cleaner response, and the stronger three-way design.
Buy the KEF Q350 only when its discontinued pricing makes it a compelling inexpensive entry to KEF’s coaxial sound.

Same family: the KEF Q1 Meta (smaller bookshelf, rated 3.6/5), the KEF Q4 Meta (smaller bookshelf, estimated 3.4/5), the KEF Q3 Meta (smaller bookshelf, ranked lower, rated 3.4/5), the KEF Q7 Meta (smaller floorstanding, estimated 3.5/5), the KEF Q11 Meta (larger floorstanding, rated 4/5) and the KEF Q6 Meta (center, rated 3.9/5).
Pros: 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. Measured bass extension of 53Hz (-3dB), with a measured sensitivity of 84.2dB.
Cons: 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.

KEF Q350: $699.00 per pair Discontinued Amazon eBay
Newer model: the KEF Q3 Meta, ranked higher, rated 3.4/5.
Same family: the KEF Q150 (smaller bookshelf, rated 3.7/5), the KEF Q250c (smaller center, rated 3.9/5) and the KEF Q650c (larger center, rated 3.7/5).
Pros: 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. Measured bass extension of 70Hz (-3dB), with a measured sensitivity of 86dB.
Cons: 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. Discontinued.
