I don't see the problem with a big room. In fact, the big room minimizes of a lot of potential problems that are the bane of smaller rooms such as early reflections, standing waves, inability to get the speakers away from room boundaries, etc.
If the intent is to fill the entire room with live sound levels, then not only are the speakers named not going to do the job, as has been pointed out, the amp isn't going to do the job either. To really pump out the SPLs without spending a small fortune on one or two super-amps, horns are about the only solution. That's just physics.
I've lived with a set of Edgarhorns for almost ten years, and while there is a lot to like about their efficiency, their uncanny dynamic jump, and their ability to play really loudly with just fractions of a watt, they are not the speaker for everyone. And, they can be hard to find used (and I don't know if they are available new anymore, though I just retired mine and would consider sending them to a good home. . .).
If however, you can live with sitting 10-15 feet from the speakers in the sweet spot for serious listening, and will be satisfied with less than live levels elsewhere in the room while other activities are going on, then just about any reasonably efficient speakers will do the job.
I'm currently using KEF 207/2s and with their 91db/w/m efficiency they do a very good job playing at levels as loud as I would ever listen within 10-15 feet. Even new they come in right around $20K.
If sufficient bass becomes a problem, there are any number of good self-powered subwoofers on the market. A stereo pair, positioned to make some use of boundary reinforcement would likely solve that problem, if it actually is a problem.
As far as room treatments -- go slow and do your homework first. Check out some of the websites (RealTraps, GIK Acoustics, ATS Acoustics), get some tools such as StudioSixDigital's AudioTools for iPhone or Android, and take some measurments. You might just find that your problems with the room are really minor.
Good luck!
