Short answer: the KEF R3 Meta, if you are buying new. The Revel M106 measures as well as it (#9 vs #10 of 134 bookshelf speakers, 4.6/5 vs 4.6/5) but is discontinued, so only consider it used; the KEF R3 Meta is still sold new at $2,499.99.
Buy the KEF R3 Meta new; the Revel M106 is no longer sold new, so it only makes sense as a used find.

Newer model: the Revel M126Be, ranked lower, rated 4.3/5.
Pros: CEA2034 spinorama shows a fairly even on-axis response with no obvious resonances, and a listening window that sits comfortably above the on-axis curve. Predicted in-room response is called “near ideal” by the reviewer, with a smooth downward slope from bass to treble. Distortion at 96dB SPL/1m stays well controlled through the midrange and treble. Measured bass extension of 60Hz (-3dB), with a measured sensitivity of 86dB.
Cons: Some directivity error and response variation shows up in the crossover region. Horizontal beamwidth of about ±50 degrees is on the narrower side. Vertical directivity requires staying within about ±20 degrees of the reference axis for accurate tonal balance. Minimum impedance dips to 4.6 ohms with several peaks, a moderately demanding load for a compact bookshelf speaker. Discontinued.

KEF R3 Meta: $2,499.99 per pair Amazon Crutchfield eBay
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.
