@123toid Yeah there I have modeled a rough max SPL.
But I do separately look at cone excursion and Le changes to compare also.
But I think WinISD shows the sensitivity the best, as if I put the same power on two subs, WinISD will show which is more sensitive.
Because I won’t do much with a number like 87dB for the sub, when my tweeters are 110dB sensitive. It seems much better to compare sensitivity with their corresponding power levels when building a system.
And it makes sense that the lighter cone subs are more sensitive, so those comparisons must have some truth to them. Also different subs will react differently to the same box, which will affect SPL.
