Max spl and spl shows the same parameters 112 db why? And 3d box is not working. Thanks
The max SPL and SPL seem to be the same on this site, the 3d box not working might be because you are using the app on a phone or maybe it was just a glitch.
If I know right, here on SBL, the only difference between the regular and the maximum SPL graph is that the Maximum SPL graph takes into account also the X-max of the speaker = at frequencies where the speaker overpasses its X-max, the maximum SPL graph drops. Similar drops are in Maximum power graph at the same frequencies at which speaker overpasses its X-max.
