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 catch: Requires in-wall installation, limited output vs standalone cabinets, and space constraints for placement.
What the Monoprice Premium Select 8in 200-Watt gets right: 8-inch ported driver still manages 106.4dB CEA-2010-A average at the lowest price of any subwoofer tested in this weight class. Set against that: Very compact 8.4 kg size, limited 106.4 dB output, ported room interaction, and entry-level build.
