I would go with the ED unless you are willing to spend a lot of effort on the seal between the cabin and the trunk. If you are willing to do that work, I would absolutely go with the IB. If nothing else, it is different and performance can be as good as anything.
The Dayton IB is used by a former CEGer in his house. Actually, Roof of Boom uses two of them and a 1000w amp. The entire house rattles.
