I would NOT add subs to those Cornwalls, with 15" woofers, ports, and high efficiency horns.
You could easily mess up what you have, it's very hard to add just the lowest ...... down to ....
You are looking at specs that say down to 34hz. that is in a test space, open air, your's are in a room, sound waves contained, reflected, your bass is maintained below 34 I suspect.
I strongly suggest you buy a decent sound meter, see what you are actually getting, and where. Look for any weak/too strong spots, standing or cancelling waves.
With that sound meter, if you add subs, (or change speaker placement) you will be able to measure/adjust the crossover/blend from your listening spot.
2 channel system: 1 pair of subs, directional, located next to the cornwalls, forward facing. Bass is stereo, and the overtones of all low frequencies also give directional cues.
