Hmm I have the a bit of paper towel in the seal as well plus the paper towel in under the pads. I'm getting excellent bass response that brings power to the bass to match the highs. This is my new favorite set up. I felt the same as you before the tape when I first put mine together. You taped the 3 open slots and not the fabric ones right?
