I'm lucky in that my wife likes all my black speakers. Currently, the sub (not an eD sub - geez, that's such an unfortunate acronym in the Age of Viagra) is back in a corner, behind a chair, and so doesn't command a lot of visual attention. It's not a very good sub, either, so the corner position helps boost its output.
If and when I ever get the money together for a real subwoofer, things may change.
