I'd go with the Rythmik - it is an exceptionally good sub and is certainly reasonably priced at $875. Start with one and see how that works. If that's not enough to load the room properly, get a 2nd one...
If 2 subs is "socially" unacceptable, consider getting something like the Rythmik E15HP which is a 15" sub. This sub should *easily* be able to provide all the bass output you'll ever need. Black matte version is currently on sale for $1024....
