I have a Samsung 60 inch led lcd and the Onkyo s9400thx. I need two things. First a recommendation for towers for the 4 surround speakers and the I'd like to know what to do with my center speaker. Is there any stand that will attach to the TV and hold the center speaker there? If I put it on the TV Stand, the height of the speaker covers the TV. I can't make holes in the wall since I'm renting. Any other suggestions will be greatly appreciated.
