>>My porblem is I lve my Axioms, but my room as of now and for the forseeable futre ( 7 years) is only 13 x 18 x 7.5 and as I was re-arranging speaker and stuff last night to see how I am going to construct the room and speaker placements I do not have much room for one EP500 let alone two or a SVS.

This is important information. For this room size you don't need to worry so much about getting up into EP600 or Ultra/2 territory. A single EP500 is one of the smallest "killer subs" you can get.
