Does any one use one of these ? I picked up a cabinet with speaker ibnstalled when Castle went to the wall. I have a plate amp for it, but there is no port tube attached.
Castle say it used a "double trumpet port tube". If anyone has one of these subs I woould like to know the length of the port and what "double trumpet" means.
