Short answer: the KEF R3 Meta. It ranks #10 of 203 bookshelf speakers by sound quality (rated 4.6/5) at $2,499.99 and is still sold new; the KEF Q350 ranks #171 (rated 3.0/5) and is discontinued, so it is only an option used. The KEF Q350’s replacement, the KEF Q3 Meta, is rated 3.4/5.
The case for the KEF Q350: CEA2034 spinorama shows a reasonably flat on-axis response with excellent directivity, aided by the coaxial Uni-Q driver. The tradeoff: Two resonances at 700Hz and 1.2kHz show up on-axis, alongside an upper-bass boost.
The KEF R3 Meta is the more accurate option. Three-way design with an unconventional concentric layout: the 1” tweeter is recessed into the throat of the 5.25” midrange driver, deeper integration than a standard coaxial arrangement. Its measured preference score, a predictor of how neutral it sounds, is 6.10 against 5.25 for the KEF Q350. Watch for: Pointed straight on-axis, there’s a 1-2dB bump around 9kHz that stays consistent across angles thanks to the constant-directivity waveguide: only toeing the speaker out about 10° tames it.
Buy the KEF R3 Meta. It is rated higher for sound quality and still sold new, while the KEF Q350 is discontinued.

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.

KEF R3 Meta: $2,499.99 per pair Amazon Crutchfield eBay
Older model: the KEF R3 (ranked lower, rated 4.5/5).
Same family: the KEF R5 Meta (smallest floorstanding, rated 4.6/5), the KEF R7 Meta (floorstanding, estimated 4.6/5), the KEF R11 Meta (largest floorstanding, rated 4.4/5), the KEF R2 Meta (smaller center, rated 4.3/5) and the KEF R6 Meta (larger center, rated 4.2/5).
Pros: Three-way design with an unconventional concentric layout: the 1” tweeter is recessed into the throat of the 5.25” midrange driver, deeper integration than a standard coaxial arrangement. A quasi sealed/ported bass alignment gives an extended low-end shelf tuned to match typical in-room gain, reaching about 50Hz for most content: deeper than recently-tested rivals like the Focal Aria 906, Polk R200, and an 8” Aperion design. Spinorama measurements show class-leading directivity and sound power, plus very linear on-axis response (at the recommended 10° toe-out) and early-reflections directivity, so it takes EQ exceptionally well. The vertical sweet spot extends to about ±20-30° off the reference axis with nearly identical tonality, unusually wide for a two- or three-way design. A clear upgrade over the earlier, non-Meta R3, eliminating the treble brightness the original had even when toed off-axis. Outperforms similarly-priced rivals (Revel M106, Wharfedale Linton, Philharmonic BMR V2, JBL HDI 1600) specifically on directivity and linearity in the reviewer’s measurements. At $2500/pair, called the best value in its class with near-reference-level anechoic performance. Measured bass extension of 76Hz (-3dB), with a measured sensitivity of 85.9dB.
Cons: Pointed straight on-axis, there’s a 1-2dB bump around 9kHz that stays consistent across angles thanks to the constant-directivity waveguide: only toeing the speaker out about 10° tames it. Minimum impedance dips to about 3.2 ohms nominal (EPDR as low as 1.9 ohms), so it needs a 4-ohm-stable amplifier; a standard AVR likely won’t cut it. Distortion crosses the reviewer’s 3% threshold around 80Hz at 96dB output and shows added deviation again near 50Hz, indicating it runs out of headroom at higher volumes: a subwoofer is recommended for loud listening. Horizontal radiation narrows from about ±70° at low frequency to ±40° at high frequency. Below about 100Hz, compression testing shows fairly wide deviations at both 86dB and 96dB output, though the reviewer notes this is typical for speakers in this size and price class. Current R3 owners who are already happy with that speaker have little reason to upgrade.
