Short answer: the KEF Q3 Meta. It ranks #89 of 131 bookshelf speakers by sound quality, rated 3.4/5, at $899.99. The Revel Performa M22 ranks #95, rated 3.3/5, at $600, $299.99 cheaper, which does not close the gap in sound quality.
What the KEF Q3 Meta does well: Coaxial two-way design (1” vented aluminum dome tweeter with Meta absorber embedded in a 6.5” aluminum cone mid/bass driver) delivering unusually wide dispersion both horizontally and vertically (about ±60° each): wider than typical KEF models, which usually run closer to ±50° horizontal and ±15-20° vertical for non-coaxial designs. The tradeoff: Not well suited to high-output use: compression and strain in the 1-2kHz region emerge above about 90dB at 10 feet, so a high-output home theater setup isn’t the best application.
Why pick the Revel Performa M22: Very flat frequency response from 200Hz to 10kHz. The tradeoff: 3dB bass boost around 100Hz.
One note: the Revel Performa M22 is no longer in production and isn’t widely stocked new anymore.
Buy the KEF Q3 Meta. It is rated higher for sound quality, and the $299.99 you would save on the Revel Performa M22 does not close the gap.

KEF Q3 Meta: $899.99 per pair Amazon Crutchfield eBay
Older model: the KEF Q350 (ranked lower, rated 3/5).
Pros: Coaxial two-way design (1” vented aluminum dome tweeter with Meta absorber embedded in a 6.5” aluminum cone mid/bass driver) delivering unusually wide dispersion both horizontally and vertically (about ±60° each): wider than typical KEF models, which usually run closer to ±50° horizontal and ±15-20° vertical for non-coaxial designs. A deliberate ~2dB bump around 120Hz gives a satisfying sense of kick-drum impact, a voicing choice the reviewer personally favors even though it’s not strictly accurate. Extended bass-shelf tuning allows placement close to a rear wall (about 1 foot) without sounding boomy. Good directivity overall means it takes well to EQ correction if desired. Cabinet resonances around 350-370Hz and 600Hz look concerning in impedance measurements, but blind ABX testing (24 trials) after adding damping material couldn’t reliably distinguish the treated cabinet from the untreated one: these particular resonances appear to fall below the threshold of audibility. Sturdier build than previous KEF Q-series models. Measured bass extension of 52Hz (-3dB), with a measured sensitivity of 84.5dB.
Cons: Not well suited to high-output use: compression and strain in the 1-2kHz region emerge above about 90dB at 10 feet, so a high-output home theater setup isn’t the best application. A slight loss of attack and clarity around 1-2kHz was noticeable both subjectively and in measurements. F3 of 52Hz with a fairly quick rolloff below 50Hz means a subwoofer is still recommended for real bass extension, even for moderate-volume home theater use. Sealed configuration (using the included port bungs) pushes the bass rolloff up into the 100Hz+ region: the reviewer recommends leaving it in ported mode instead. Sounds best pointed directly at the listener; toeing it out 30° rolls off the top end without a meaningful soundstage benefit. Compression testing shows real breakdown at 102dB/1m, with the woofer losing excursion control: confirms the practical output ceiling. An unexplained -5dB dip appears in on-axis measurements that the reviewer couldn’t attribute to a specific cause.

Revel Performa M22: $600 per pair used (about) Discontinued eBay
Pros: Very flat frequency response from 200Hz to 10kHz. Distortion is well controlled through most of the range, with only a modest crossover-region bump around 2-4kHz. Measured bass extension of 46.9Hz (-3dB).
Cons: 3dB bass boost around 100Hz. On-axis response also droops below 150Hz and peaks above 4kHz, which the reviewer thought may sound a bit bright/light. Distortion rises substantially below 100Hz when driven hard. Discontinued.
