That's a good setup you've got. Mesmerizing, I bet.
What you want for bass are four subs. Don't have to be big, powerful or expensive. Just have to be four. The smaller the room the more important its four. Because multiple subs creates much more smooth even bass than any one can ever do. I know, I tried.
Which speakers you have doesn't really matter either. As long as they have good useable bass down to below 80, which yours definitely do. Because below 80 the bass is no longer localized and so the subs can go anywhere.
If your amp has a low bass roll off crossover you can use that and it will take a lot of load off your amp. Even without it though you will probably be fine. Just adjust the subs to fill in.
Just to give you some idea, here's mine. https://systems.audiogon.com/systems/8367 Five subs, three different types, placed asymmetrically around the room. Don't have any sub recommendations, don't think it matters all that much. What does matter is how many and where. Four, different distances from corners, done.
