Thank you very much for providing. I inputed these and got a green light for integrity check. I checked, and the graphs are the same, but it's good to know that it is in properly now. The Vas in the spec sheet is 53L but WinISD calculates it as 49.6. I guess that's what it wasn't liking that I was putting in as a value. I also added the Xmax value in, and the integrity check is still fine.

My comment wasnt meant to suggest something was wrong with porting this driver. Its very common for winisd to not give the correct result in the real world by a few hz. Just use winisd to tune lower than desired and build it like that, then you should get close to your desired result. Most people dont check their tuning so you dont hear much about it.
Thank you for clarifying that.
So it seems after all of this I've pretty much come full circle back to wanting to design a vented setup. I have learned a lot in the process though!!
I am struggling now with the port design.
, I tried inputing what you suggested, with the 6" wide ports, but not sure what their height should be? I also get too much cone excursion and air velocity when I play around with these. I am not going to be playing the sub at max levels, so I don't know if 300W would be the right power to put for signal. Maybe 200?
I also have a question about the HPF I am putting into the program. What is the difference between Butterworth and User SOS?
Many thanks again to everyone for your input.
