Will a subwoofer add depth and clarity to my system, or just bass?


hi folks,
I just purchased a set of Focal Aria 906 speakers with stand, powered by a Bluestream PowerNode (not my ideal system but I had a limited budget).  I think it sounds really good, but am wondering if an upgrade to a subwoofer is worth it, and if so, what would pair well with this system -- my audio guy recommended the JL Audio D110 10" Dominion Subwoofer, but that's out of my price range.  Perhaps a SVSPB1000, for $499?  My room isn't very big, and I don't use the system for movies, just listening to mostly jazz and rock (and classical).
Thank you!

@hornguys I was really surprised to see your post - from the author himself! I mention this because I ordered your book (& DVDs) just 2 days ago after having read many good things about it on several sites/forums including AG.

I must admit I was a bit concerned when I read @noble100 's comments that seemed to indicate the book was perhaps outdated. However, I do feel better now after seeing your response :-) 

I'm looking forward to the book for advice and help on improving my setup at home, any further tips are most welcome!
