Short answer: the KEF R3. Both are rated 4.5/5 for sound quality (#15 and #21 of 131 bookshelf speakers), and the KEF R3 costs $2,200 against $5,390 for the Perlisten R4b, and with sound quality even, the cheaper one is the better buy.
What the KEF R3 does well: True three-way stand-mount with a 6.5-inch woofer below KEF’s 5-inch Uni-Q midrange/1-inch tweeter. The tradeoff: 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.
The case for the Perlisten R4b: The Ear’s dedicated review called it excellent value that punches well above its weight, and the measurements back it up: a 0.209dB on-axis deviation and 0.676 listening-window smoothness that are strong for a sealed standmount this size, with a fairly neutral on-axis tonal balance (a mild -0.16dB per octave tilt) and a predicted in-room smoothness of 0.66. Watch for: Sealed acoustic-suspension loading trades reach for control: the measured -3dB point is 80.3Hz, shallow bass extension for a standmount this size.
Buy the KEF R3. Both are rated the same for sound quality, and it costs $3,190 less than the Perlisten R4b.

The Two Speakers In Full
KEF R3: $2,200 per pair Amazon eBay
Pros: 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. Measured bass extension of 35.2Hz (-10dB), with a measured sensitivity of 87dB.
Cons: 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.

Perlisten R4b: $5,390 per pair Audio Advice eBay
Pros: The Ear’s dedicated review called it excellent value that punches well above its weight, and the measurements back it up: a 0.209dB on-axis deviation and 0.676 listening-window smoothness that are strong for a sealed standmount this size, with a fairly neutral on-axis tonal balance (a mild -0.16dB per octave tilt) and a predicted in-room smoothness of 0.66. THX Ultra certified, with a 3-way DPC-Array design (dual midrange domes flanking the tweeter) that’s unusual at this price.
Cons: Sealed acoustic-suspension loading trades reach for control: the measured -3dB point is 80.3Hz, shallow bass extension for a standmount this size. It’s sold only in Piano Black through specialty AV dealers rather than mainstream retail.
