Short answer: the ELAC Debut 3.0 DF63. Both are rated 4.2/5 for sound quality (#84 and #85 of 228 floorstanding speakers), and the ELAC Debut 3.0 DF63 costs $1,298 against $1,398 for the Polk Reserve R500, so with nothing between them on sound quality, price settles it.
Why pick the ELAC Debut 3.0 DF63: Affordable three way floorstanding speakers with a dedicated midrange, low distortion when played loud and good dispersion for the money. Watch for: A genuine measured resonance around 200-300Hz (visible in frequency response, impedance, and group delay) causes an audible “droning” coloration on female vocals.
The Polk Reserve R500 is the deeper-bass choice. Affordable floorstanding speakers with fairly neutral sound for a small to medium room, easy to improve further with simple EQ. Its bass reaches about 51Hz before falling 3dB, against 71Hz for the ELAC Debut 3.0 DF63. The catch: A bump around 4-6kHz gives a “shouty,” mildly sibilant quality in the lower treble.
Buy the ELAC Debut 3.0 DF63. Both are rated the same for sound quality, and it costs $100 less than the Polk Reserve R500.
