I think people are assuming it is a dedicated listening room - I wish :-(
It's going to be one very large open plan space, with living room + dining + kitchen.
Sadly won't be able to any gear beyond the couch area, so I only have the wall that the TV will be at. This is one reason there will be no rear speakers also but I'm quite happy with just 2 or 3 speakers at the 'front' anyway.
It's going to be tricky because even if I can have the subs symmetrical, the room itself is not.
