Default Where is this mythical subwoofer?

It is not uncommon to see the pyramid, or triangle. of things you can have in a sub woofer. but physics will only allow you to have two. never three.
Small size
Deep bass
Cheap.

So where is this mythical cheap deep bass in a large enclosure. Is this where tapped horns fit in? something like the kraken 2X12?

Check Parts Express for buyout speakers and dumpsters for free wood, create your own myth :^).

My tapped horn "Tub Sub" uses two $5 buyout 10" speakers, is 99 dB one watt one meter in half space at 60 Hz (open field) but located against the wall behind the outdoor hot tub, 24 Hz is only -3 dB from 60 Hz, with a "loudness contour" peak at 40 Hz.

The third leg is "efficient," not "cheap."

Five or so years ago there was a liquidation company selling off a TON of Bazooka returned merchandise, much of it with nothing wrong. $10 or so as I recall per 12" driver and several people put a couple dozen into a wall to good effect.

Are we referring to Hoffman's Iron Law?

Well. I thought I was referring to that. Apparently where ever I had copied it from was incorrect. This was not intended to be a which sub is better thread. Or anything like that. I was just wondering if I was missing something that was right in front of my eyes, but it was so obvious I was overlooking it.

Hoffman's iron law: loud, low, or small-pick two.
If you don't mind spending a lot of money, you can have all three, but the box won't be efficient.

In general, modern sub drivers are being designed with more Xmax, allowing more output with less efficiency.

Not sure I would say "general", cheap high powered digital amps fuel the small box high excursion varieties. Most likely due to the highest profit, easiest sell to the ignorant masses who may never realize that while it does play loud and will play low, it won't do loud and low at the same time.

I'd say most common sub continues to be a moderate sized ported box (or functionally same passive driver instead of a port).

High end are big boxes, some are horns, some are just big.

efficient, low, small, is the way that doesn't need qualifiers.

There are some solid inexpensive sub drivers out there. Zalytron's clearance 1201PL is a solid woofer for $20 per, less if you buy 8. They might need a little TLC to get the suspension back to "flat" but not much.
