Short answer: the Polk Reserve R600 on measured sound quality, the Emotiva Airmotiv XT1 on price. The Polk Reserve R600 ranks #90 of 226 floorstanding speakers, rated 4.2/5, at $1,438. The Emotiva Airmotiv XT1 ranks #136, rated 4.0/5, at $699, $739 cheaper.
What the Polk Reserve R600 does well: Slim floorstanding tower in Polk’s flagship Reserve series combining a 1-inch Pinnacle ring radiator tweeter with dual 6.5-inch molded Turbine Cone woofers. The catch: Rating estimated from measured Reserve series siblings (Polk R200, Polk Reserve R500, and Polk Audio Reserve R700).
The case for the Emotiva Airmotiv XT1: The entry Airmotiv tower below the Emotiva Airmotiv XT2, with the same folded ribbon tweeter, a 4.5” midrange and three 5.25” woofers, rated at 89dB. Watch for: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers.
Buy the Polk Reserve R600 if sound quality matters more than the price. Buy the Emotiva Airmotiv XT1 if the price matters more than sound quality.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: Polk Reserve R600 4.0 to 4.4; Emotiva Airmotiv XT1 3.7 to 4.3). Treat this verdict as provisional.

Same family: the Polk Reserve R100 (smaller bookshelf, rated 3.4/5), the Polk R200 (larger bookshelf, rated 3.2/5), the Polk Reserve R500 (smaller floorstanding, ranked higher, rated 4.2/5), the Polk Audio Reserve R700 (larger floorstanding, ranked higher, rated 4.3/5), the Polk Audio Reserve R300 (smallest center, estimated 3.6/5), the Polk Audio Reserve R350 (center, rated 3.7/5) and the Polk Audio Reserve R400 (largest center, estimated 3.8/5).
Pros: Slim floorstanding tower in Polk’s flagship Reserve series combining a 1-inch Pinnacle ring radiator tweeter with dual 6.5-inch molded Turbine Cone woofers. Leverages Polk’s patented down-firing Power Port 2.0 and Cross-Bracing cabinet tuning for smooth low-frequency extension down to 38Hz without port chuffing. Exceptional listening-window linearity and controlled high-frequency dispersion inherited from the comprehensively measured Polk R200, Polk Reserve R500, and Polk Audio Reserve R700 lineup siblings.
Cons: Rating estimated from measured Reserve series siblings (Polk R200, Polk Reserve R500, and Polk Audio Reserve R700). 4-ohm nominal impedance with dips into low-impedance territory requires an amplifier capable of supplying solid current during demanding dynamic passages.
