Mark: Since no two projectors are the same size, and many will evacuate air in different ways, building a hushbox is pretty much always a custom job.
I know a lot of people around here that have hushbox's for their ceiling mounted PJ's, and they're all custom DIY builds. Those with enough money for custom installations don't buy them pre-made either - they're all custom builds as well.
