I've looked at many drivers now and it's actually not that easy for me to find a 10" model that is rated at 8 Ohms and will work good enough in smallish enclosure. Space wise, I was hoping to get by with 30 liters or less. With 60l or so, things would be easier.
The SB SW26DAC76-8 (in a 2x 10" push-push setup with a HPF at ~1900µF looks most promising). The Peerless XLS-P830452 was also looking good but it only comes in a 4 Ohm version so I'd have to connect the pair in series which I gues I should avoid...
This is how I think it might look like. 45x45x26 cm with a separate chamber for the amp module. Vb = 28 liters...

Nice! I would suggest to seperate the woofers from each other. Thiele small Parameters are never exactly the same. With two seperate enclosures for the woofers, these small TSP diferrences will not effect the sound quality. Tolerances of 1 to 5% are quite normal between pairs.
SB Acoustics has a nice range of 8 ohm 10 inch woofers with big x-max in the 9 mm range. Alu and even some with ceramic cones,

When I put the drivers in separate enclosures, I'd be loosing the push-push effect of "impulse compensation", wouldn't I?
If they are opposed-mounted on either side of the enclosure, operating with same electrical phase but opposed motionally, then an internal partition matters not in terms of opposed forces being cancelled. It would only serve to isolate the drivers and brace the cabinet.

First thing that comes to mind when I hear high quality and compact sub is a ripole.
Yes, it's inefficient but other than that the best bass for the size IMHO.
Maybe some drivers in too small an enclosure plus linkwitz transform are able to rival it.

I agree about the ripole subs, but is a bit of an acquired taste, I would not recommend a ripole to someone who has not heard dipole / ripole bass. And that in it itself is a big problem, it is nearly impossible to hear a ripole sub anywhere, Plus the minor inconvienence that it needs to be placed well away from any walls. Zackplonk has 3 x 4 meter room.
Wolf_teeth is right about the seperate enclosures, No downside of two slightly different drivers, only the plus of the cabinet vibration cancellation.
It's a pity all the small AB class plate amps are going the way of the Dodo, Would be nice to have a range of 80, 150, 250 Watt alternatives to class D available. With 0-180 phase option and highpass in. I have fond memories of a cheap 100,- euro Conrad 250 Watt AB plate amp. Not longer made. The Monacor SAM 2 comes close at 300 euro.
How is the relation x-max / max power with the SAM 2?

If you're still considering driver options, the seas l26roy is a 10" sub that goes in a small enclosure (40 litres) with an f3 in the 20s

Not heard it but I wanted to purchase in the past so read a lot about it. Seas also have an application note on that page which gives some nice information about their goals with the woofer, enclosure sizes and a bit about the PR too

Thanks for the pointer.
It seems these only come in a 4-Ohms version. For connecting them in parallel in a push-push configuration, that would yield too low of an impedance so I‘d have to wire them in series which is not ideal unfortunately…
