Short answer: the Polk R200, if you are buying new. The Revel Concerta2 M16 ranks higher than it (#62 vs #178 of 222 bookshelf speakers, 4.1/5 vs 3.2/5) but is discontinued, so only consider it used; the Polk R200 is still sold new at $799.
The Revel Concerta2 M16 is the better-sounding, deeper-bass option. An affordable bookshelf speaker with essentially flat mids, a pleasing in-room balance with extra bass, and low distortion. Its bass reaches about 60.1Hz before falling 3dB, against 74Hz for the Polk R200. Watch for: Harmonic distortion shows a notable peak around 80Hz and a sharp spike around 350Hz, plus the woofer appears to get a bit unhappy right before handing off to the tweeter.
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.
Buy the Polk R200, since the Revel Concerta2 M16 is discontinued and only worth hunting down used.
