So you comparing 1 sub that is located how many feet away(6',8',10'?) vs one that you had 5" from your back?
If that is the case I would say that is why they are not even close. I know from trying just 1 Um18" sealed nearfield behind my seat I have never had that kind of effect from multiple 15" and 18" spread throughout my room.
Put your new sub behind your seat like you had your SVS and it should be a better comparison.
