In my bedroom system I don't have a lot of room and some recordings have bass that my tiny speakers simply don't even hint at.
So I added a sub (Golden Ear Subx). I really had to fiddle with placement so I could hear the bass from my bed. A standing wave prevented it going in the spot I felt was the most convenient. That's the thing about one or two subs- you have to fiddle to get it right. I kept the sub output below 70Hz so it would not attract attention to itself, and then just worked with the level so I really was getting the bass notes. The main speakers roll off at about 60Hz (KLH model Nineteens) so this worked out pretty well.
A Distributed Bass Array would have worked better (I could have heard the bass throughout the room rather than just near the bed) but since the goal was listening from my bed that was not important.
