When you look at drivers, when they give a sealed vs ported enclosure they all seem to have a small sealed enclosure, and a vented enclosure twice the size.. For example the 15" Ultimax im sticking in one of EricH's flat packs calls for a 3.1 cubic ft sealed enclosure and a 6.1 cubic foot vented enclosure..
I was playing around with some web program on google, types in EricH's flat pack diemesnions and stuck a 3" diameter 13" long port for a port size and It said it was tuned down to like 20HZ IIRC
but what is the reasoning behind having a bigger enclosure? if the enclosure is to small and ported does it harm the driver? or can you really just stick a 3" port in a box like that and get the output you want...
Excuse my ignorance, especially if this is something thats been answered or talked about countless times, just not finding the answer, or maybe its not in simple enough terms that I am realizing the answer is in front of me.
