Depending on your budget and on the physical size of a speaker that would be suitable for your room you may want to consider the Daedalus Argos. Click on the "specifications" box on the left side of the page for detailed specs.
As an owner of their Ulysses model, which differs from the Argos mainly in that the Argos is designed to provide a much wider sweet spot, I suspect it could very well meet your requirements. I don't know what current pricing is, but as a very rough guess I wouldn't be surprised if it is in the vicinity of $20K.
Good luck. Regards,
