Well, I've been doing a bunch of reading about low frequency sounds and how they basically go through everything that can be done easily/cheaply. Given that sub placement will become more critical to optimize the efficiency of the sub to my ears, the EP500 will be a bit easier to place in my room than the EP600 (unless I could switch between the vertical and horizontal versions effortlessly). I'll keep the buttkicker in mind if the EP500 isn't enough for me (I had a couch in college with a pair of 12" subs inside it, so know that feeling very well). Hopefully the neighbors will not be too bad (I'll try to break them in slowly) and I can crank things up from time to time.
