Yeah, I've got those plans, but thanks. Those plans are for a different driver, not the one I have already.

OK, I'll give it a try. Thanks!

You could make a conical horn 65cm long that would hit 100Hz in 1/2 space with your driver.

I can't seem to duplicate that in Hornresp. The conical horn is still 1 meter long. How did you do it?

I would not do that you will be fooling your self you because it will not make a perfect fit with the corner. Calculate 1phi and hope you get that as result in the corner half-space.
