Short answer: the Polk Audio PSW10. It ranks #17 of 48 subwoofers by sound quality at $209; the Klipsch HD Theater 600 ranks #25 and costs $399, so there is not much of a tradeoff to weigh.
What the Polk Audio PSW10 offers: 10-inch Dynamic Balance polymer composite driver with 100W Peak Class D amp. Deep bass capabilities are impressive with exceptional definition/control per CNet. Reduces distortion (uncommon at this price). Good hard clean bass performs well at higher volumes. Easy setup and affordable price consistently highlighted by thousands of buyers. Polk Power Port channels airflow cleanly for tighter bass without port noise. Best for average/small rooms and apartments. Watch for: Budget-tier construction, ported room dependency, lower 110.3 dB output, and $250 entry-level positioning.
What the Klipsch HD Theater 600 offers: Independent CEA-2010 testing records 108.2 dB (avg of 3/4 bands) through 40-80 Hz. The ported, rear enclosure with 8” (203mm) driver is a compact way to add useful midbass support to a modest system. Watch for: Without a published 20 Hz result, deep-bass capability is less certain than the midbass figure. The 353.1H x 317.5W x 317.5D mm cabinet and 7.7 kg mass still need careful placement and calibration.
Buy the Polk Audio PSW10. It ranks higher for sound quality than the Klipsch HD Theater 600 and costs less, so there is no real case for the other one.
