You should probably look at using a sealed box and using a huge amplifier, otherwise the size gets huge.Going from 40hz to 20hz and keeping the efficiency fixed dictates the box size increase by a factor of EIGHT.
I picked the -3dB point at 27hz for the reason that it's the lowest note on a piano.
Doubling the size and going to 15s will only gain you 3dB of efficiency.
Pick two of three, efficiency, cut-off frequency, size. Once you pick two, the other is fixed.
