Short answer: the Audio First Cadentia 3 for better sound quality, the Polk R200 for the lower price. The Audio First Cadentia 3 ranks #7 of 222 bookshelf speakers, rated 4.7/5, at $7,199. The Polk R200 ranks #178, rated 3.2/5, at $799, $6,400 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. Watch for: 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 Audio First Cadentia 3 is the more accurate, deeper-bass option. A large three way bookshelf speaker with near textbook accuracy, a big enveloping soundstage, and deep, punchy bass that stays clean when loud. Its measured preference score, a predictor of how neutral it sounds, is 7.55 against 5.09 for the Polk R200. Its bass reaches about 43Hz before falling 3dB, against 74Hz for the Polk R200. The catch: A mild scoop through the upper midrange/lower treble slightly softens the attack of snares, hand claps, and sibilants: fixable with a single-band EQ (2.5kHz, +1dB, Q~1).
Buy the Polk R200 if the price is the priority over sound quality, or the Audio First Cadentia 3 if sound quality is the priority over the price.
