Doorway in to my HT

When you say "solid white door", I assume you mean solid as in no glass/windows. Is it a solid wood exterior door or a standard hollow core interior door? Have you done any other sound isolation in the room?

If you haven't done any other sound isolation in the room (insulation, double drywall, etc.), the doors probably aren't going to make sound isolation much worse. Someone else will have to comment on the glass with the sub. I would guess that if the sub is that close, you will probably have issues with the glass rattling. I also don't know what issues the glass would cause with sound reflections. I'm sure someone will chime in soon.

As far as light, it depends what is outside the door. If it is a hallway with no windows and the lights can be turned off, it may not be as much of an issue. Some light will make it through the glass, so you would have to come up with a way to control it (which may defeat the purpose of wanting the glass doors). Maybe you could hang some curtains in the room that could be open/closed.

I personally would avoid this type of door in a theater, but that's just my opinion.

Tell your wife that if she can find any commercial theater with an all glass door to the theater proper you will get behind her 100%. If the door leads to a hallway that has a couple of turns you have a glimmer of a chance of controlling the light.

If you could install black-out curtains on one side of the door you could probably manage the light transmission fairly well.

As for vibrations, if it is a well-built door with fully glazed panes it likely wouldn't rattle any more than a regular 6 panel door. If it is just an interior door with panes that are pinned in place or just contained by rabbits, it would probably become rattle-city over a period of time.

Maybe a glass panel over a solid door, would give the look outside the theater, but not the negatives?

Sorry Raj, that particular design will not keep the rumble of the sub woofers in the theater. You got some bad advice somewhere in the contracting process.

Sound board and insulation is not an effective strategy at low frequencies, ask to see their data.

An excellent place to learn about soundproofing is to read the library of articles at soundproofingcompany.com. What I'm trying to point out is that insulation and hanging soundboard is a solution suitable for reducing the sound of people talking between two rooms. It is not a soundproofing strategy to keep the sound of a home theater from reaching adjacent rooms. If you were told it is you were misled.
