Checking out the C&S remix as I type.

Someone post the correct HR inputs for that TC 18 sub.
TC Sounds Pro 5100 18 1K rms 4K peak 19.1 X 38.1Xmech 94.5db 2x2 ohm
So 19.1 is Xmax and 38.1 is Xlim - not Xmax ?
I used a general SD of 1680 and went from there. Put it into my TH 221 clone sim and get 137 DB at 20 Hz 2 Pi 133 v ! Though 24-28 Hz cause some issues. You could just build a single one of these and have it vertical with permanent caster like the Th 812 from Danley.
I think that would dismantle a house!
150 Db at .5 pi @ 20 Hz. Bajeebus ! Would make me nut my pants at full tilt.

And tx klank for the posting about that remix.
I do like the rap over it. Will use it to flip the script on the original.

Quick update:

After looking at ported, front loaded horn, and tapped horn, the tapped horn is looking the best for efficiency and output. The first graph is 1vs2, the second graph is 2vs4 half space, and the third graph is the excursion plot at 976w.

Compression ratio is way too high for an 18" driver, but other than that, you're getting there...

Not speaking for Wi directly, but knowing the others involved with this, I'm pretty sure things will be shared once the course is decided.
