DSpeaker Antimode 2.0 or 2 more Subs?

Help me decide what to do next.  A buddy came over and we ran Sonarworks reference 4 on my system. Well I really liked what I heard but I don’t want my system to habe to be entirely ran off a laptop so I was thinking that the DSpeaker Antimode 2.0 would be a better option for me.  What I don’t like is the idea of an extra ada converdion.  I also don’t like the idea of just increasing bass where I have a 6 db dip between 40hz and 120hz.  
So that brings me to a different option for smoothing out the bass and that would be to add a pair of sealed, wireless, dsp 8” subs.

I currently have 1 Rel T5i centered between my speakers.  2 more subs in random places in my room might be a betrer option than the DSpeaker... 

What do you guys think?  Either option will cost the same.  The deal on the subs is limited, the deal on the dspeaker could probably be had anytime..
