Room Acoustics With Vaulted Ceiling

Hey Goners--I did a search and did not see a thread sufficiently similar to my situation. About to move in a few weeks. Right now my system http://https//systems.audiogon.com/systems/3224 is in a small, rectangular room (11.7 W X 17.3 L X 7.5 H). Speakers are on the short wall spaced nearly 8 feet apart and I am sitting around 10 feet away. The sound is surprisingly good for such a tight space. The new room is larger (13.6 W X 23.5 L X 8 H) with a vaulted ceiling that rises to at least 14 feet at the center of the room. I'm going to set up on the short wall again (no choice on this one) and am wondering what I can expect in terms of room acoustics. For those who have experience with a similar room, what blessings and curses would you anticipate? I'll circle back after the move with an update but any suggestions for room treatments etc. are welcome.
