Actually, irregular ceiling heights help to keep standing waves from forming. The beams won't have much effect (unless you hit your head on them) but I'd recommend you center the speakers under the 3 foot wide duct facing the longer side. You also should deaden the sheet metal duct using that rubberized material along with more stiffening to keep it from sounding like you have a kettle drum in the room!
Ceiling acoustics
Can anyone tell me how uneven ceilings affect acoustics? My (recently-expanded) listening room is in the basement, and the ceiling is crossed by two beams and ductwork. The room is about 13' X 27'. The ceiling is about 8' at the tallest and 7' at the lowest (i.e., at the location of the beams and ductwork). The first beam (about one foot wide) is at about the 12' mark (crossing the longest dimension), ductwork is at about 15' mark (and it's about 3 feet wide) and the final beam is at the 20'-21' mark. So, the ceiling goes up and down. How will this affect the sonics and what can I do to remedy any problems? (We move in on 3 Feb, so I can't listen and see what it sounds like.) Thanking you in advance for your responses!
