Short answer: the Perlisten S4b if sound quality matters most, the ELAC Debut 2.0 B6.2 if price matters most. The Perlisten S4b ranks #2 of 222 bookshelf speakers, rated 4.8/5, at $8,000. The ELAC Debut 2.0 B6.2 ranks #149, rated 3.5/5, at $329, $7,671 cheaper.
The ELAC Debut 2.0 B6.2 is the deeper-bass option. Large bookshelf speakers that play very loud with low distortion and decent bass, a solid budget choice. Its bass reaches about 64Hz before falling 3dB, against 78Hz for the Perlisten S4b. The tradeoff: A good size resonant peak around 700Hz stands out from an otherwise smooth response and lingers in cumulative spectral decay (waterfall) measurements: in one reviewer’s sighted A/B test, reducing it by about 5dB via EQ made a noticeable but not dramatic difference.
The Perlisten S4b is the more accurate choice. 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 4.75 for the ELAC Debut 2.0 B6.2. 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 ELAC Debut 2.0 B6.2 if the price is the priority over sound quality, or the Perlisten S4b if sound quality is the priority over the price.
