A friend and Me got bored and Built a box that can be Sealed or Ported at the flip of a switch.
We designed and installed a motor drive that can close or open the port from inside the box. The only thing needed is to hook-up power the motor drive system "Signal Wire and Ground"
We tested it to make sure it did not leak air or vibrate when closed. It seems to work fine. We will test it over the next few months as well.
Question is, What else should we look for other then freq test?
