Short answer: the MoFi SourcePoint 10 on measured sound quality, the Polk R200 on price. The MoFi SourcePoint 10 ranks #27 of 222 bookshelf speakers, rated 4.4/5, at $3,795. The Polk R200 ranks #178, rated 3.2/5, at $799, $2,996 cheaper.
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 4.16 for the MoFi SourcePoint 10. 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.
The MoFi SourcePoint 10 is the better-sounding, deeper-bass option. A large bookshelf speaker with a 10 inch concentric driver that acts like a point source, with a huge soundstage and strong, clean dynamics. Its bass reaches about 56Hz before falling 3dB, against 74Hz for the Polk R200. The catch: Like virtually all coincident designs, sounds notably bright pointed directly on-axis due to a deliberate treble lift (meant to compensate for the 28mm tweeter’s earlier beaming versus a typical 25mm/1” tweeter) combined with a diffraction dip/peak from the waveguide edge; needs about 15° of toe-out to sound neutral, and even then benefits from an extra 1-2dB of treble EQ.
Buy the Polk R200 when the price outweighs sound quality for you, and the MoFi SourcePoint 10 when sound quality outweighs the price instead.
