Short answer: the Polk Audio PSW10. It ranks #3 of 42 subwoofers at $249; the ELAC IW-S10EQ in-wall ranks #25 and costs $299, so there is not much of a tradeoff to weigh.
The case for the ELAC IW-S10EQ in-wall: 10-inch in-wall driver delivers 103.9dB CEA-2010-A average with EQ-adjustable response for flush installation where a floor-standing. The tradeoff: Requires in-wall installation, limited output vs standalone cabinets, and space constraints for placement.
What the Polk Audio PSW10 gets right: 10-inch Dynamic Balance polymer composite driver with 100W Peak Class D amp. The tradeoff: Budget-tier construction, ported room dependency, lower 110.3 dB output, and $250 entry-level positioning.
One note: the Polk Audio PSW10 is discontinued, but it still ranks #3 of 42 subwoofers, ahead of most of what is still sold new, so it is worth considering used.
Buy the ELAC IW-S10EQ in-wall if the price matters more than the ranking. Buy the Polk Audio PSW10 if the ranking matters more than the price.
