I have a room that is 20x18. The hometheater is on one of the long sides. The current placement for the svs 20-39 is in the corner to the right of the tv. This wall goes for about 8 feet and then opens up to the dining room. The other alternative would be to put the svs on the left in the corner by the window. There is no opening by sub then but it is farther from the seating area. There is a opeing across the room from it. What do you guys think before I start moving this thing around? Thanks!
