Lounge is approx 7m x 3.5 (rough drawing below) Not wanting any floorstanding speakers or bookcase ideally due to room restrictions so ordered a bunch of Polk MC80 ceiling speakers (no AV receiver ordered yet but looking for 2 or 3 zone denon or yamaha). TV will eventually be mounted on the wall in the centre of this rectangular room but for now is on the far right of the room. My plan was to put 2 x ceiling speakers towards the front tv wall on the left and right, then 2 more left and right at the back of the room above the sofa and armchair. A polk ceiling centre speaker with the angled tweeter can go in the ceiling in the middle but up the front of room above TV. Will get a sub to put at rear of room tucked away. Will this sound any good???
