Short answer: the XTZ Spirit 4. It ranks #159 of 222 bookshelf speakers by sound quality, rated 3.4/5, at $477; the Polk R200 ranks #178, rated 3.2/5, and costs $799, so there is not much of a tradeoff to weigh.
The Polk R200 is the more accurate option. A Polk bookshelf speaker with a 6.5 inch woofer and a ring radiator tweeter, sized for a medium room. Its measured preference score, a predictor of how neutral it sounds, is 5.09 against 4.18 for the XTZ Spirit 4. 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 XTZ Spirit 4 is the deeper-bass choice. Stand-mount speakers with a waveguide tweeter, adjustable treble and port tuning, wide coverage and fairly deep bass. Its bass reaches about 40Hz before falling 10dB, against 50Hz for the Polk R200. Watch for: The third-party measurement is low confidence.
Buy the XTZ Spirit 4. It is rated higher for sound quality than the Polk R200 and costs less, so only choose the other one for a particular feature it does better.
