Hi. You can type there any input power to see different results on the cone displacement, SPL, port airspeed graphs. It may be RMS or peak power or half of RMS.

If you choose a speaker from the local database, primarily Pe = the speaker's RMS power. In past primarily it was peak, or max power, but there were made some changes, and now it is the RMS power. Also, you can change it - for exanple to optimize your box for a different power you need - using the same speaker, or something like that. The differences will be visible on those graphs which Alex wrote you above.
