31Hz
Yes.
25 cubic foot exterior, 708 liters.
Two cabinets use five 4x8 sheets of plywood.
Yes, it could, though 30Hz was -6dB from 40 Hz.
The excursion minima is probably closer to 35Hz than 30Hz, with 40 volts probably could expect around 123 dB at one meter reaching Xmax at 31Hz.

The builder, a Peavey dealer, had limited cabinet building experience, but he followed the directions well.
The simple cabinet design worked pretty darn good 16 years ago, considering the drivers used, and no simulation used prior to the design.

Dude, it preceded the THAM by almost three years, and the cones won't sag like the Thams 😉
Brian Steele did about 8 years after the design was made, seems to be close to the response I measured:

Sure, but at the end THAM became more famous and know by people.
The cone sag is just by positioning the cab not by it's layout
Yeah , that's because tham was rolled out when there was more activity in the DIY community plus was posted in more forums and in martinsson blog page.
Art did not care about being a star in the DIY movement as he had enough to do doing live pa gigs.
Besides tham is more complicated to build.
And only have one driver.

Is getting there, tomorrow i will post the 2D views with dimensions.

Why won't the cone sag?
I thought a cone could sag when in a horizonal position?
To me, the THAM enclosure position below prevents cone sag.
To me, these are cone sagging positions.
I noticed I had some things sagging due to the summer heat when I sat on the toilet and there was a cold splash sensation
