Apparently it falls to me to help add confusion for you.
That's usually Jack's job, but he is napping. I concur with Tom - future proof if you know you are going to larger digs; at the very least, plan on the 2 EP175s. (little known fact - 2 subs gets you extra credit on your Man Card).
However, I must take umbrage to your comment about not much going on under 25hz. It is a secret and active place, especially in some DVDs that have been mentioned on the board. the 20-25 space is WHY you get a sub. Embrace the dogma that one cannot have too much LFE. It is good to bleed your ears once in awhile.
