You do this using multiple subs. If your main speakers are good into the 20s then you only need two to do the job.
They must be asymmetrically placed. In most rooms they must not reproduce anything above about 80Hz else they can draw attention to themselves.
Standing waves can cancel bass or reinforce it. If its being cancelled, no amount of room correction or bass traps can fix it since amplifier power is being cancelled in the standing wave.
At 80Hz the waveform is about 14 feet long. The ear needs the entire waveform to pass it so know the note is there; a few more iterations to know the frequency and nature of the note. By that time anything below 80Hz has bounced all over the room probably several times. Deep bass is thus 100% reverberant. So a mono bass signal for the subs works fine and you don't have to time-align anything.
At that point you can get smaller rooms, even ones that are square to play bass just fine.
