Pinwa, in the spirit of plowing with the horses you’ve got, I like Erik’s idea of plugging the port(s) on the mains and then overlapping the mains and subs. If the Moabs have multiple ports, you might leave one open.
This might work as a plug: https://www.zoro.com/test-tite-t-cone-combination-cleanout-test-plug-4-86400/i/G3337302/
Its maximum diameter is less than 4 1/4" but you could expand it to the maximum and then wrap the perimeter with duct tape until it fits snug. To remove the installed plug, unscrew the orange piece to relieve the expansion pressure and it should come out easily.
But try Erik’s T-shirt suggestion before ordering the plugs because a rolled-up T-shirt will work just fine.
The Moabs will still be low-bass sources even after port pluggage, but not as loud. So now you can turn up the subs a bit louder. And you can use different crossover settings on each of the two subs to smoothe the blend. I’m under the impression that repositioning the subs is not practical, but I glanced at the specs and apparently they have phase controls. Use them, and they can have dissimilar settings and still work well.
