Ya, I knew about the iris, and many other issues with this projector....but I found many issues with "every" projector I read about at the AVS forum.
I doubt the iris noise will bother anyone here with the projector mounted well above, and a little behind the listening area, and if it does, I'll turn it off.
At the price I paid (around what I paid for my old Infocus X-1) many years ago......I expect I will be "more" than happy!
We don't use our projector much anyway.....less than 3,000 hours on the Infocus bulb even after all these years (-:
