DC Level 4 15" burp box

I also suggest you to flare the pvc tubes, that way, once you buy the aeroports, you don´t have to start testing port depth again, once you flare the pvc, you´ll see your peak frequency changing, this is how i did my portS:

Common sense should tell you, you cut how long at a time to change tuning the reconnect then flared part of the port to the base. When you buy the port it comes in 3 sections. 2 flares and a base. Hope this clears it up for you.

I understand all of that. I just was wondering how to change out the swappable ports. For daily and burping. Tuning isn't a problem. I'm sure I need to buy another port, but do I pull the base out of the mounted end and replace it with a different one? Or do I have to unscrew it from the inside of the box? Or Unless I just misunderstood what you were saying. By the way, fecupe, thanks for the vid and the advice, I think I may need to get a bowl and do that to the pvc.
