Short answer: the KEF Q Concerto Meta. It ranks #11 of 222 bookshelf speakers by sound quality, rated 4.6/5, at $999.99; the Perlisten R4b ranks #21, rated 4.5/5, and costs $5,390, so there is not much of a tradeoff to weigh.
The KEF Q Concerto Meta is the deeper-bass pick. A neutral three way bookshelf speaker that sounds consistent from seat to seat, with smooth treble that many rivals at its price lack. Its bass reaches about 35Hz before falling 10dB, against 45Hz for the Perlisten R4b. 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: 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 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.
