Has anyone used the SVSound subs with variable tuning? I'm interesting in the port plugs. I know they're foam, and that's about it. If anyone has one, do you think you could maybe take pictures and/or measure them?
I've emailed svs about them but I don't know if they'll respond, as it's been a while. Hopefully I can come up with something on my own. Aren't pool noodles closed cell foam?
