Ummm I’ll try again. Need more coffee lol.
So please forgive my archaic iPhone art. I would mount the speakers so the back of them is flush against the ceiling, so the front of the speaker is pointing straight toward the floor. Since the front of the speaker has the tweeter and the woofer at different angles(vs one flat baffle) it’s important to aim the tweeter towards the LP. In this example the tweeters are to the outside edges, therefore pointing them at the LP.
Alternately, having the speakers mounted so the tweeter is fore and aft, the tweeter would fire like this.
Does that help any? I can doodle up some more HD diagrams per request LOL!!!!!
