Thanks Oliver, can't wait to see what you come up with.

Wish I going to be in Austin early summer for the Black Sabbath show! I had tickets to see them in 79 when they fired Ozzy and cancelled the tour.

That is a single fold! A double fold might get the port to exit the same side as the speaker.

My double fold was to short, made it about halfway to the front of the cabinet. I needed to add an extra 8 to 10 cm, which when I modeled the mod to L23 jacked up the response. Obviously I am not as good at this as Oliver!
