Short answer: the Perlisten S4b on measured sound quality, the Polk R200 on price. The Perlisten S4b ranks #2 of 222 bookshelf speakers, rated 4.8/5, at $8,000. The Polk R200 ranks #178, rated 3.2/5, at $799, $7,201 cheaper.
What the Polk R200 does well: A Polk bookshelf speaker with a 6.5 inch woofer and a ring radiator tweeter, sized for a medium room. The catch: A resonance and associated distortion increase around 800Hz-1kHz creates a “tinny,” occasionally glaring quality on certain instruments and vocals, confirmed both by ear and in the frequency-response and distortion measurements.
The Perlisten S4b is the better-sounding pick. 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 Polk R200 when the price outweighs sound quality for you, and the Perlisten S4b when sound quality outweighs the price instead.
