Short answer: the Perlisten S4b if sound quality matters most, the Dynaudio Emit 20 if price matters most. The Perlisten S4b ranks #2 of 222 bookshelf speakers, rated 4.8/5, at $8,000. The Dynaudio Emit 20 ranks #133, rated 3.6/5, at $1,049, $6,951 cheaper.
The Dynaudio Emit 20 is the deeper-bass option. Bookshelf speakers with unusually deep, low distortion bass for a two-way design and wide, consistent dispersion. Its bass reaches about 54Hz before falling 3dB, against 78Hz for the Perlisten S4b. The catch: A resonance around 600-800Hz gives snares and similar percussion a muffled, flat quality lacking impact: confirmed as originating in the woofer itself (isolated via measurements of the raw driver out of the cabinet), and attempts at constrained-layer damping didn’t resolve it.
The Perlisten S4b is the more accurate option. A compact sealed bookshelf speaker with reference grade accuracy, exceptionally smooth dispersion, and very low distortion at high volume. Its measured preference score, a predictor of how neutral it sounds, is 5.35 against 4.22 for the Dynaudio Emit 20. The tradeoff: Erin measured only 84.5dB sensitivity and an impedance minimum just under 4 ohms, a difficult efficiency/load combination that deserves substantial clean amplification.
Buy the Dynaudio Emit 20 when the price outweighs sound quality for you, and the Perlisten S4b when sound quality outweighs the price instead.
