I read in another thread about the idea of a port plug (used by mlstrass and others) and wanted to know who uses them, and how they do it.
I use an SPL box (5 cf w/big port @ 50-53 Hz for burpin'), but I'd like the flexibility to demo on Gucci or Gorilla Zoe, and not sound like sheez.
The port plug would ideally tune the system down to 38-40 Hz, according to my sealed box response.
How do you (properly) make one?
