Short answer: the KEF Q Concerto Meta. It ranks #11 of 131 bookshelf speakers by sound quality, rated 4.6/5, at $1,399.99; the Perlisten R4b ranks #21, rated 4.5/5, and costs $5,390, so there is not much of a tradeoff to weigh.
Why pick the KEF Q Concerto Meta: Really good in-room neutrality with consistent horizontal directivity from seat to seat. Watch for: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment.
What the Perlisten R4b does well: 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 Q Concerto Meta. It is rated higher for sound quality than the Perlisten R4b and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

The Two Speakers In Full
KEF Q Concerto Meta: $1,399.99 per pair Amazon Crutchfield eBay
Pros: Really good in-room neutrality with consistent horizontal directivity from seat to seat. Directivity holds remarkably steady from lower treble into upper treble, where many similarly-priced speakers narrow sharply as frequency rises: one of the reviewer’s top 10 picks under $1,500. Measured bass extension of 53Hz (-3dB), with a measured sensitivity of 84.2dB.
Cons: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment. Needs to be pointed closer to on-axis rather than heavily toed out: combined with its rolled-off, shelved-down top end, too much toe-out makes it sound noticeably dark.

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.
