The company was sold after some problem after his founder death.

@ USRFobiwan

The option A and B were left in the past, due to diaphragm displacement i tunned the project to safety region, you can find it on the history or wait some more posts will i complete the build so i will repost the design again.

@ turbodawg

Yeah, i simulated all drivers from the list posted on the topic #105 and I don't recommend the B&C 15TBW100 for this spec, see below the response @2,83V. To use it you should change a lot the dimensions.

Left the frequency response comparison between Snake HPX2150 and B&C 15TBW100, and right just the B&C one.

I never build a bandpass cab, from what I read till now, it can be more efficiency then tapped horn but, people always complain about it being a kind of "one note" cab and it maybe this came from high distortion additionaly it has more restricted bandwidth frequency response. So I think for who need just SPL it's a good option, for who need SPL and HI-FI response looks like Tapped are way better.

There are many guys much more experience then me to help you in this case.
