I am considering adding a small sub to my home theater. My room is only 250 square feet. I have never been a big fan of a lot of bass in my audio listening experience. Are there other advantages other than creating a more pronounced "thumping" to adding a sub woofer? I am trying to find a used Wharfedale WH-S8, or WH-S10. These sub woofers were matched with the WH-2 center and surrounds but all are discontinued now and difficult to find.
