Default Does furniture obstruct modal resonances?

Does furniture (ie couches, tables, etc) obstruct modal resonances (ie 20-150hz) or LF sound propagation. Suppose a subwoofer is placed beneath a couch or under a table, does the furniture attenuate its output or direct its energy to different areas of the room (ie excitement of different modes)?

I think not. The furnitures are too small for the room modes. Or I guess they should be in particular proportion to make influences -- like a very large bed in a very small room, or something like that.

I've experienced many times that the tables (large flat reflective surfaces) near the speakers cause irregulations in midrange, say, 500Hz or so.

What about LF propagation? Lets say a couch was placed atop a subwoofer array, would the array still sum the same as if the couch wasn't present?
