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!

Duke "Regarding adding a sense of depth or sense of envelopment/immersion, if you have two subs, you can place one at either side of the listening position and dial in 90 degrees of phase difference. "

Probably a dumb question, but I have my two subs phase set to 0.  To achieve the above should I leave one at 0 and turn the second to 90?  Does it make a difference if I put one at 90 and the other at 180?  Is one better or even different than the other?
 Thanks
