Volume Displacement For SPL Chart
shows the inch units (imperial) for displacement for 50Hz and 110dB to be about 15 to 20 cub inches.
the next post shows the centimetre units (SI).
I would expect a single 12" driver to get pretty close to your SPL target.
I told you not to guess.
I can't make heads or tales from that chart, but if you say one 12 inch unit is enough, than using 2 per will give me 6 db headroom. Thanks !!
