Ended up going with HSU STF-2 since I found a killer deal on it from a local seller, and the eD site does a build to order type of thing on their subs.
I plan on getting a 2nd HSU STF-2 as well. Great sub, can't go wrong. However, I do think that the eD is the better sub for HT. Heard both of them, eD for HT, HSU for Music.
