The REL's all work basically the same way. That is a big room. So get the biggest you can afford.
Or.... if your budget can fit it, actually get two subwoofers; one for each stereo channel. If the subs are of very good quality, stereo subs are better than one, especially in a large room.
Setup is just as easy. You just run one stereo channel to each sub. For HT, you will need a splitter on the HT decoder if it only has one output.
