With the generic 80hz lpf, that resonance shouldn’t be a big deal.

Sure, SI HST18 and double the amplifier. But that costs way more and now your port velocity is going to be stupid.
The UM18 is the best bang for the buck you’re going to find for a HT woofer.
Since you’re constrained to those dimensions, I’m assuming additional boxes are out. And higher performance subs need a larger box due to port velocity. So I really don’t see you finding a better option than the UM.
You can model the Dayton HO, I can’t remember off hand if its happier in a smaller enclosure.
EDIT: Check out GSG’s performance table here:
It shows quite a few of the popular and highly regarded woofer options. Remember, your box falls between a cube and a mini, closer to the cube side.
Based on that, I’d model the SAF184.03 as well. Its out of stock everywhere till the end of the year though. Its also an 8ohm driver, so may cause you amplifier issues.
