The receiver has been chosen. Marantz sr6005. Now, I would like to know the best in wall speakers for a cost conscious budget. Dual sub or just one. Room is 18'x15' and open to the second story. Wife has agreed to make this purchase for Christmas. I see the Atlantic Tech. speakers on the blowout list and like the price but were they really sold for $600 each. Any help for the newbie would be appreciative.
