Short answer: the ELAC IW-S10EQ in-wall for better sound quality, the Yamaha HS8S for the lower price. The ELAC IW-S10EQ in-wall ranks #21 of 48 subwoofers at $2199. The Yamaha HS8S ranks #36 at $775, $1424 cheaper.
What the ELAC IW-S10EQ in-wall offers: 10-inch in-wall driver delivers 103.9dB CEA-2010-A average with EQ-adjustable response for flush installation where a floor-standing cabinet isn’t an option. Watch for: Requires in-wall installation, limited output vs standalone cabinets, and space constraints for placement.
What the Yamaha HS8S offers: Independent CEA-2010 testing records 104.8 dB through 40-80 Hz. The ported, front enclosure with 8” (203mm) driver is intended to add useful bass support without a full-size cabinet. Watch for: Without a published 20 Hz output result, deep-bass capability is less certain than its midbass figure. The 349.2H x 300.0W x 388.9D mm cabinet and 10.2 kg mass still need careful placement and calibration.
Buy the ELAC IW-S10EQ in-wall when sound quality outweighs the price for you, and the Yamaha HS8S when the price outweighs sound quality instead.
If sound quality matters at all to you, skip the Yamaha HS8S. It ranks near the bottom of the 48 subwoofers, so look higher up the list instead.
