Hi I currently have a hs10 but it is proving too noisy. I am thinking of replacing it with a vw12ht but need a bit of info first. Do both projectors have the same throw distance, so i dont need to change my projector mounts position. Also do both projector have the ceiling mounting holes in the same place. Finally i have the CC40R filter for the hs10, do i still need this filter for the vw12ht. Thanks for any help you can give.
