In my setup as you will see in the DCR thread, I have a no port glass.
This is because I have a hush box connected to the back wall of the theater and it vents to the attic.
So for air circulation - air gets sucked in from the port into the hush box and up into the attic (Dennis Erskine Design also).
But I loved the way Jeff is set up - now off course he has a equipment room behind the back wall of the theater with adequate cooling (split air conditioner) and ducting etc...
So mine is a compromise because I wanted a Lobby at the entrance and no two glasses in front of projector lens..
In very quiet rooms which Dennis designs - If I sit at the back row - with the 5000 being quite noisy and the exhaust fan running (which also makes noise) - I would rather have a setup like Jeff.
Actually If I want, I can modify my hush box also in which case I could put a vent in the bottom of the box for air suction.
So either way it is a compromise - two pieces of glass in front of lens - or sound from the fans and projector - you pick your poison.
