I am not sure the in ceiling M3s are right for ATMOS in my setup. I'd love to download a manual. Are the tweeters aimable?

I will be looking at options with tiltable woofers and tweeters. The speakercraft aim line is of interest so far. I have to look into it further.....

I'll cut to it. $530 for a pair of in ceilings is a little higher than I was hoping to spend. Lots to choose from in that range.
