For a lot of reasons, I'd vote for an alternate placement. You've got that basement, so why not use it as a rear chamber? You might be able to use the volume "as is", without building a proper rear chamber. In this case, assuming stereo configuration, do you think it would be necessary to separate the basement into two volumes so the drivers do not communicate with each other via the basement?

With regard to power; In my case, in a room that appears larger than your current space, 100 watts for each driver (2 x M1.1) seems to be more than enough; driver sensitivity is nothing special; 94db. I'd expect the amps could run 4 of these drivers with no problem; it would be easy enough to connect the pair to a single amp and find out. I can do it if you want.

"...good luck to find 18” driver with sub 25Hz resonance..."

I only know of one; if we can believe the specs, the McCauley 6174 has Fs at 20Hz.
