I'm not sure you need two subs. Scheme with two subs is often used when you need to equalize bass in large listening area (home theater with many rows of seats). For fixed listening position one sub properly placed should be ok especially one that can equalize (with microphone) itself like JL Audio Fathom F113.
Do you still like your HPS-938? There is some "ease" and something very relaxing in their presentation but they are also very snappy and dynamic at the same time.
