Short answer: the ELAC Uni-Fi Reference UBR62. It ranks #65 of 222 bookshelf speakers by sound quality, rated 4.1/5, at $1,299. The Polk R200 ranks #178, rated 3.2/5, at $799, $500 cheaper, not enough of a saving to outweigh the sound-quality gap.
The ELAC Uni-Fi Reference UBR62 is the better-sounding, deeper-bass choice. A three way bookshelf speaker with a coaxial tweeter and midrange for stable imaging, well controlled tonality, and front ports for easy placement. Its bass reaches about 58.6Hz before falling 3dB, against 74Hz for the Polk R200. Watch for: Erin measured very low 83dB/2.83V/1m sensitivity; his 110W Parasound was insufficient for the high-level test and the more powerful HINT 6 was needed.
The case for the Polk R200: A Polk bookshelf speaker with a 6.5 inch woofer and a ring radiator tweeter, sized for a medium room. The tradeoff: 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.
Buy the ELAC Uni-Fi Reference UBR62. It is rated higher for sound quality, and the $500 saving on the Polk R200 is not enough to make up the difference.
