A couple of things: No room treatment will be able to cure a bass peak as you describe. So that’s out.
I looked up your speakers and Dynaudio lists them as near field monitors. You say you’re sitting 10 feet away. Wrong tool for the job?
Is this a new house or room? If not, did the room ever sound satisfactory? Unfortunately bad rooms will remain bad rooms. You can put lipstick on the pig but it’s still a pig.
So, let’s say it is simply a bad room. Your best chance at improvement would be a sealed box alignment perhaps with a smaller woofer that would be less likely to energize the rooms 70hz bass mode.
