Does your small space need more bass? Soundmatter promises that you can hide this subwoofer wherever you see fit, including under your couch.
The SUBStage Stealth Subwoofer offers the power of a regular subwoofer in a tiny and flat package. (16.7"x8"x4.5" to be exact.) And if one isn't enough, you can stagger multiple ones around the room.
The SubStage200 ships in July and will cost you $399.(via Chipchick)
