If you can provide a link to the driver data it makes the job easier.

My understanding is that most PRO drivers make relatively poor sub-woofers for home use

That's bass guitar speaker. I wouldn't think it would make much of a subwoofer even if you are planning to use it in a car.

It may indeed work out OK....Heres' the Thiele Smalls.
fs=35Hz
Qes=.47
Qms=5.36
Qts=.43
Xmax=6.2mm
EBP=75
Sens. 92Db
...40-2K Hz.

Low Xmax, high Fs and 33 gram cone. Not your average subwoofer.

50 litre vented will give good response down to ~40Hz but not much power handling.

The amount of power from the amp it takes to drive the speaker to it's linear limits (Xmax). In this case, about 80 watts.
