For around 100l, the best pro woofer size is usually 15". Maybe some 12" or two 10".
I don't say that only a pro woofer can have real punch, but have you ever heard a pro sound system with lack of punch? And this is not only at high SPL, even at lower levels the sound is clearly more punchy.
Of course midrange and treble with good integration is important but for good bass the woofer is the main factor IME.
I don't know if you ask me, but i replaced the SS 26W for an Eminence Kappalite 3012LF, i placed it in a 70L vented box and never looked back.

In my opinion this woofer is too delicate for having well defined bass, motor is too weak and its linear displacement is too low. You're asking too much out of it. What is more, the box is tuned too low and port radiation peak falls over borders of hearing frequency so it is just useless, inefficient and it is just a waste of already tiny resources of this woofer. You can make the port shorter in order to bring tuning frequency a bit higher but this will be only marginal help. Graphs from sims software are only the hints, true problem lies in the woofer itself.
If the OP's measurements are correct, the crossover is following acoustical LR2 topology.
At xo point the sum is exactly 6dB more than the individual driver responses. If you flip the polarity on woofer in this situation you get a big null in the lower midrange.
But maybe it worth a try.

I did not heard this driver, but on paper it looks much better.
The 110l vented box tuned around 30Hz is near ideal for this woofer.
The linear xmax is not so much but this is a 12 inch woofer and it needs to move far less than a 10 incher.
Looks really good indeed.
It looks like you did not accounted for any baffle step loss in you crossover. What is the baffle dimensions?
Lojzek's simulation looks realistic if you have the usual rectangular box speaker.
But then below 100Hz there is usually some room gain. An inroom response would be great from the listening position.
