My ears at my listening position are 100" from the tweeter so if I've done the trig correctly, seven degrees down would be just over 12" or 27" off the floor. So maybe slouching with my ears at 30" isn't a big deal? But I swore it sounded better when my ears were higher at the level between the mid and tweeter at 37". Clearer highs and better soundstage. Maybe it was my imagination.
I know MTMs don't sound good if your ears are up or down too much from the level of the tweeter. Does the mid-range of the Ottavo interfere with the sound from the tweeter when my ears are below the tweeter? Do the little two foam pieces on the front of the tweeter have any impact on the sound above or below the tweeter?
