MTX or Subthump?
I believe that MTX unit is self powered -- the subthump box will need a separate amp to power them and will cost you more money.
Do not associate subthump with Elemental Designs -- wherever/whoever you are purchasing this from just decided to pair that sub in that box.
Between the 2 options, I would go with the ED/subthump setup.
Thumps loud and clean it's awesome.

I would go with Subthump so you can pick the brand name sub you want.
I have their amp rack they do good work.
MTX subs suck ballz, period.
