Yes, I understand what you're saying and can understand how this can be confusing. However, remember, the transducer surface area (actually I think PG would contend the transducer surface area is increased, but remember he comments extensively that its movement is decreased) and maximum excursion capability is unchanged. This defines a physical limitation of the motor system.You're correct that a widening or changing of the baffle dimensions will change the dipole bass performance. Lengthening the front/back cancellation distance and thus lowering the roll-off point. That's a trade-off though. The maximum SPL capability of the system can't be increased. You could mount the transducers in an infinite baffle and totally isolate front and back. The limitation still remains. To realize higher SPL capability you have to move more air. This requires a larger diaphragm or increased excursion or both.
Hope that answers your question.
Dave.
