I just had ceiling speakers installed in my Master Bedroom (Proficient Audio C870's), which, by design, have the woofers ANGLED at 15 degrees. Unfortunately, only my wife was home when they were installed, and the installer positioned them with the woofers aiming inward, towards the center, rather than outward. They sound pretty good as is, but it seems to me the soundstage would be even wider if the woofers were angled outward. Of note, the owners manual/installation guide does not specifically recommend angling them one way, or the other. It would be a royal pain to rotate them 180 degrees to hear if there is substantial improvement. Should I bother?
