MartinLogan Dynamo IW-O
Best in-wall subwoofer for home theater enthusiasts seeking space-saving bass.
This in-wall subwoofer delivers massive, room-filling bass without sacrificing a single inch of floor space. By opting for an open-back design, you gain significantly deeper output than standard sealed alternatives, though you will need to manage sound leakage into adjacent rooms to keep the performance contained.
