I don't think that they are upselling you. That is a gigantic room, and if you look around you will find posts where SVS has suggestd a smaller sub than the poster thought they needed. One of the owners actually posts to this site as well, (Ron) and he has always been a very well spoken person that seems willing and to answer questions he receives, even if he is saying that another sub will perform well for someone. Another plus of SVS is that they seem to have outstanding customer service. The same can be said of arch rival HSU. Great products, great word of mouth, great service. YOu won't go wrong with either company IMO.
