I have to agree with millercarbon on this one, that is that a DBA would be the way to go.
That's a really large room for two 11" woofers!
I see that the rear of the speakers has speakers terminals labeled "Bass Input". Does that mean you can bypass the internal cross-over? IF so, then you can, go here:
https://www.marchandelec.com/xm44-electronic-crossover.html and purchase an external crossover (2 way any slopes you like and control the gain as well) requires a second amp of course.
The cross-over will run you about $1500-$1700, depending on options, like fully balanced, tubes etc.
Then borrow an amp and give it a try, seems to be a cheap experiment given the $$$$ you are willing to spend.
