Interchangable ports

What are the pros and cons of an interchangable port? Are they worth doing? I love low bass but need the higher tuning for competitions. I was thinking 32hz for daily and 45hz for competitions. Or should I just compromise and just do like 37hz-38hz for daily/competitions!

Your Explorer peakes at 45Hz you don't want to tune your burp port to that because of rise. You need to tune it to around 42-43Hz.

So if I do an interchangable port I should tune the higher one to 42hz?

sounds about right, just got with aero's cut to different lengths. that would be easiest

If he tunes at 38, his response may actually peak at 42, he needs to

graph it.

This is correct but he would have to get someone to build diffrent ports for him to test.

Are you running your 4 12" Rd Alpha's?

What size box?

I highly recommend using external aero ports. They're extremely easy to change for different tunes and with them being external there's no change in box volume.

I wont have the room to make them external...

Then just take into consideration that when you shorten your ports for a higher tune you'll also be adding to the box volume and in effect changing the tuning.
