I have two speakers for my bed listening, they're logitechs as well, maybe even the same model.
I'll say that ultrasonics can indeed bypass noise, as long as you're not trying to sleep through a concert, it's more than fine. Shannon in fact tested this theory in a party/concert situation some time ago and it was proven to be effective EVEN in that environment. Ultrasonics seem to "fly above" all normal conscious hearing stuff. Picture a stealth bomber flying over WWII AA guns lol.
I will say you seem to have quite a drop off in decibels, that's a concern. Keep in mind angling the speaker JUST so makes a big difference in volume, it does for my speakers too. Try to angle them as good as you can, I move around a lot in my sleep and it can be a pain. I have set mine up a bit differently, I have them set so that no matter where I am in the top part of the bed, the speakers are no less than -50db, so it's a variance of -35db to -50db which is good. I may have a smaller bed than you so YMMV, but that's been a good system for me. Except I don't dream with ultrasonics and I'm making a thread to ask Shannon if this is a concern or not.
Hope that helps you!
