"Sealed" VTF for music!

[Poo]

I have noticed that my VTF sounds better if I plug both ports when listening to music; I use a towel for the port that comes open. I can imagine how it would sound if I could have a better seal. Does HSU sell extra port covers? If not, what can i use for a tight seal?

The sub was not designed to be sealed, and plugging both ports will result in loss of performance.

Have you properly calibrated the sub and systesm, as well as played with placement?

That said, I am sure you can get another plug fro Hsu.
