Hornresp calculates mass rolloff as you've described. I think it will do a pretty good job for Adrian too. Either way, mass rolloff is a description of what can be expected from the horn when the diaphragm moves as a rigid piston. When the cone begins to flex - undulating across its surface - it will modify upper frequency response from that predicted by mass rolloff.
