"I have a 15 foot ceiling and about 20 x 30 room", Norm .... I hate you already.
This IMHO is the perfect size for an audio room, especially the ceiling height. There's a cavet here though; high rooms have an inherent eco. A coffered ceiling with tile inserts would solve the isssue (hey, it's only money, ya make it every day). But as you say you're not the owner.
Also treatments tend to be NWF, so may I suggest a draping. You can hang drapes with dowels .... what ever. One guy I knew center hung a parachute with a good result. Grant it that's not everyone's cup of tea, all I'm suggesting is that there are creative, decorative, cost effective ways you can use to mitigate your accoustical issues. Fact is you have an oustanding system there, so to take it to the next level it would appear is to tackle the room nemesis.
You may also want to audition the Logan's ;-)
