Bandpass systems that operate with high pressures can often produce SPL in that range inside the enclosure! So, if you put your mic in there (assuming it can handle that SPL) you would indeed see over 160 dB at that frequency. Most living rooms would really start to get stressed at over 120 dB in the lower ranges. At 145 dB SPL at 11 Hz, the room would probably even seem to list or lean! :Q
The cheapest way to (torture) get that high of a SPL within an edifice is to dig a large pit underground and partition it with a wall of 7000 psi concrete say 50 cm thick. This becomes your baffle for 128 or more 18" high excursion (60 mm xmax) transducers. An array of Crown Macro Tech 10k amplifiers producing 700 kW (480/277 three phase power line required!) would power the beast.
Sit in, strap down and play something like a close miked 16" howitzer recording within 6 dBW of the array. The purchase of life insurance would be recommended as La-Z-Boy's aren't (yet) equipped with air bags!
Cheers!
