Short answer: the Perlisten S4b on measured sound quality, the SVS Prime Bookshelf on price. The Perlisten S4b ranks #2 of 222 bookshelf speakers, rated 4.8/5, at $8,000. The SVS Prime Bookshelf ranks #150, rated 3.5/5, at $599, $7,401 cheaper.
The case for the SVS Prime Bookshelf: Affordable bookshelf speakers with a sealed woofer compartment, wide even dispersion and reasonable sensitivity. The tradeoff: A scooped mid-range paired with a boosted upper mid-range creates an audibly uneven tonal balance, and there’s an additional dip in the treble around 4-5kHz that reads as slightly tinny relative to the recessed mid-range.
The Perlisten S4b is the better-sounding choice. A compact sealed bookshelf speaker with reference grade accuracy, exceptionally smooth dispersion, and very low distortion at high volume. Watch for: 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 SVS Prime Bookshelf if the price is the priority over sound quality, or the Perlisten S4b if sound quality is the priority over the price.
