I'm mounting a 40-inch Bravia (KDL40EX640) on our bedroom wall. I've read that the sound on these tv's are pretty bad so I would like to look for some better options. The wife won't let me mount any speakers and it would have to be pretty small/discrete. I was thinking maybe a wireless speaker of some sort, but need ideas on where to put them. Also, do they make small, wireless soundboards or center channel speakers that I could put on our table under the tv? Looking to spend no more than $200, if possible. What are my options?
