One thing to consider is the environment a subwoofer is measured in. Most are stating a ground plane measurement. That's reasonable since it is easiest to do and is where the subs will be used. But it's 3dB louder than free space. A woofer that is capable of, say 93dB/W/M from 40Hz to 100Hz as a direct radiator in freespace would measure 96dB/W/M in a ground plane measurement. A pair of these in a sub cabinet would measure 102dB/W/M.
