Short answer: the KEF R3 on measured sound quality, the Revel Performa M22 on price. The KEF R3 ranks #15 of 130 bookshelf speakers at $2200. The Revel Performa M22 ranks #94 at $600, $1600 cheaper.
What the KEF R3 offers: True three-way stand-mount with a 6.5-inch woofer below KEF’s 5-inch Uni-Q midrange/1-inch tweeter. Erin measured approximately 86-87dB/2.83V/1m sensitivity, exceptionally low sub-1% distortion at 86dB and orderly directivity in both planes. The coaxial geometry maintains image stability across seats, while Flexible Port Technology avoids the strong midrange port resonance common to rear-vented competitors. A 110W Parasound drove it successfully in Erin’s listening. Watch for: The low-frequency alignment rolls gradually rather than delivering high-output sub-bass; KEF specifies 58Hz +/-3dB and Erin’s high-level data supports using an 80Hz subwoofer crossover. Narrow high-frequency features and natural Uni-Q narrowing toward the top octave make toe angle audible, although off-axis tracking remains smooth. Sensitivity is moderate, the cabinet weighs almost 30 lb, and this original R3 lacks the Meta successor’s MAT absorber.
What the Revel Performa M22 offers: 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. Watch for: 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.
Buy the KEF R3 if sound quality is the priority over the price, or the Revel Performa M22 if the price is the priority over sound quality.
