I just put my order in for the Tempest-X it should be her soon

. Anyone have any suggestions for sonosub design using tempest. I have a piece of sonotube 5'4" long 24" dia. I am hoping someone here is using this setup for this sub with good results. I would like to go big as possible and tuned as low (within reason) as possible. The gross volume of the tube now is 475L so I have that much to work with, I'm sure this is to big.
