Using WinISD To Help Design A Speaker Box

I found out quickly that I'll need a program to help me design a speaker box. It turns out the program I found to use is WinISD. Here I go through what it looks like to use.

Hi. I like the videos from you so far. Got a couple of questions: 1-What is better - tune port to higher frequency or to a lower one than the fs? 2-if able to tune below the fs, how much lower, 5,10 or 15hz lower than fs? Keep up the amazing box building! Thanks.

I appreciate you checking out the channel. I can't answer your questions with certainty but some reading seems to have people typically going slightly above Fs. If you use WinISD start by what it picks for you, it defaults to the theoretical best provided you have driver specs loaded correctly.
