I just recently bought a pair of KEF Q7 for my room and am having some problems with placing. I have no choice but to put them in the corner to either side of my TV. I was wondering if anyone had any suggestions on how to get the most out of my speakers. My room is pretty much a rectangle and I would be listening mostly for a chair that is about 5 feet from the tv.

In the store from which I bought the speakers they had this black panels on the walls around the room and I was wondering what exactly these do and if that could be an option I should look into.

Thanks
