Short answer: the KEF R3 Meta. It ranks #10 of 222 bookshelf speakers by sound quality, rated 4.6/5, at $2,499.99; the Perlisten R4b ranks #21, rated 4.5/5, and costs $5,390, so there is little reason to consider the other one.
The KEF R3 Meta is the deeper-bass option. A three way bookshelf speaker with KEF’s coaxial driver, superb accuracy that holds across the room, and bass that reaches deep for its size. Its bass reaches about 37Hz before falling 10dB, against 45Hz for the Perlisten R4b. The tradeoff: 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.
Why pick the Perlisten R4b: A THX certified sealed three way bookshelf speaker with smooth, fairly neutral sound and excellent value for its class. 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 Meta. It is rated higher for sound quality than the Perlisten R4b and costs less, so only choose the other one for a particular feature it does better.
