w2olves, is there an absolute limit to the inner enclosure volume? I was wondering about a potent and yet small Tang Band unit for a woofer but these are very modest SPL so you'd rely on a more powerful amp to drive it sufficiently loud.
What about a mini Karlsonator? They give very good bass extension in a very small box. And they are ridiculously cheap to make. There is a lot of info on this forum on how to build them and a lot of posted measurements.

Yes, TC9FD is a cheap unit but it is also unsuited for the application. A lawnmower motor to be deployed in nascar racing.

I have seen the comment for Boenicke, how about a clone of those by a german distributor?

I had a few pair of the JohnBlue Audio JB3 for a short while. Amazing little speaker that sounds much, much larger than it is. It was fun to prank people by setting them on a larger speaker, no one could believe it was the JB3 playing.
Will they play loud? No. But within limits, they are amazing, and I don't know how they do it. Tiny driver in a box that looks too big for it. Just a bass reflex with minimal stuffing, no crossover or EQ. For organ or dubstep, you'd want a sub for sure. FOr most music and desktop use, they are amazing.
Never did figure out how it was done. Didn't get to measure anything, never had the time. But if you could build something like it, dad would be happy.

Just thinking aloud, why not take a pragmatic, mixed approach?
Instead of trying to make the cabinet by itself meet contradicting specs, why not start "backwards" and solve each problem when it appears?
As in:
1) determine what space you *do* have available (which seems to be the excluding factor).
2) search for projects which fit in that space.
Pick the one which best approaches your requirements.
You might find one which does so straight as-is but I´m not holding my breath, get as close as you can.
It *might* use a 6" woofer , or two 6", or a 6x9 , simply based on smallest footprint possible.
A "tower" design might increase enclosure volume while keeping footprint small.
3) add EQ as needed.
Is that "cheating" ?
Not at all, consider all high quality active speakers, specially Studio monitors, include a lot of internal EQ to compensate for small size, extend LF response and tame pesky peaks and dips every real world speaker has.
4) you will need more power than expected because it will have to make out for speaker "deficiencies" ... no big deal.
Watts are inexpensive, small and light, the real problem lies in the acoustic side.

Some good, well documented options here: Zaph|Audio
I built one of the small sealed 2 way versions and they sound nice for my office. Ported will go lower, but add a small sub and off you go.

I would suggest a 6.5" coaxial that will fit in a smallish enclosure:
Overview
Then a separate enclosure with a smallish (to me 8" or 10" sub), with this amp set up to drive it built into the sub enclosure:
PDA330I - PDA Series - Marani Pro Audio
or this for even more power
PDASP2SA2 - PDA Series - Marani Pro Audio
For the sub enclosure you can have a fairly high power speaker, and substitute some efficiency and depth of frequency response by doing a higher order box.
