It depends on the specific drivers, listening level, and what sort of low frequency peaks you get in your source material.
Maximum displacement limited output from a monopole in free space is 102.4 + 20log(one-way driver travel) + 20 log(driver area) - 20 log distance distance with travel, area, and distance all in meters (squared for area).
SPL at one meter for various example drivers around their linear limit (where the length of voice coil within the magnetic gap drops) is listed below for 80/40/20Hz.
Size Driver Sd (cm^2) x xmax (mm) 80Hz 40Hz 20Hz
5 1/4" Peerless 830873 88 x 3.5 88dB 76dB 64dB
6 1/4" Seas L16RN-SL 104 x 6 94dB 82dB 70dB
7" Seas W18EX001 126 x 5 95dB 83dB 71dB
8.5" Seas W22EX001 220 x 5 99dB 87dB 75dB
10" Peerless 830452 352 x 12.5 111dB 99dB 87dB
At your listening position you probably loose 3-5dB (it's not the 6dB/doubling you get outdoors due to the reverberant field) and there's a similar margin between xmax (around where the driver stops being linear) and xmech (where it runs into your mechanical limits) so those are close to the points where drivers stop making louder noises.
When reaching those limits some drivers will be damaged, often by their voice coil former banging on the motor back plate.
