Short answer: the SVS SB-1000 PRO, well ahead on output. Its 12-inch sealed driver delivers a 113.9dB CEA-2010-A average, which the page calls the highest of any subwoofer in the under-30lb (13.6 kg) class, against the ELAC’s 103.9dB. The ELAC’s EQ-adjustable in-wall design is the reason to pick it, but it needs a wall cavity; the SVS still brings room-mode sensitivity and a compact ported design.
Buy the SVS SB-1000 PRO. It is rated higher for sound quality than the ELAC IW-S10EQ in-wall and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
