Xmax since Xsus and Xmech isn't published. Then there's the rapid rise in distortion to consider.

At a glance it would be ~92dB in half space to keep it within Xmax....

So you expect that at 92db at 50Hz at 2m is all I can expect fom the JX92. This is not bad. few drivers this size can do this.
I expect to have "some" boundry reinforcement; not that the speaker will be close to the walls but it might get within 1m of the rear wall and that might bring the low freqs. up about 3db.
thanks though for all this info.
