I have built a cabinet, as well as tested and listened to another one of my designs that someone else built.
With respect to mine - As usual, I learned more about what not to do....
I encountered problems with my build, my testing, and my design. Why not cover all the bases, that way you have no idea what is wrong. Honestly - I learned a lot - experience is a powerful teacher, bad experiences even moreso.
At least I did not kill the driver or my amp in the process. I did waste a LOT of plywood though. Oh well, at least I can cut it up into little pieces and keep the shop warm with it.
The other design? Well, we learned a bit about how not to brace a tapped horn, but I think that the results with that one were positive enough with that one to warrant further work and sharing in the future.
It is BIG. Bigger than the F-20 big. Like big enough that 2 guys can barely carry it big. If you have to move it - an appliance dolly is definitely a good idea.
We're still working on a few changes to that design, but it will be shared soon.
This one is a 16 Hz tapped horn loaded with a Kicker Comp VX 15. The cabinet is about 30 cubic feet (from memory), almost 6 feet tall, just over 2 feet high, and just under 2.5 feet deep. Approximately 92 dBs at a watt in, groundplane, and will take a kilowatt without complaining (with a steep highpass at 15).
We listened to a pair powered with an EP4000 bridged into 4 ohms (two 8 ohm cabinets in parallel). Quite an experience. Clipped my Omnimic at the seats long before we ran out of sub or amp. SPLs were in excess of 120 dB, distortion was still in the single-digits.
