French Doors

Theo is correct that you can have a custom size door made to fit the opening and not have to go through the extra work to reframe and drywall/ paint. You may have to do some research as to who can make this door for you. And be careful that someone doesn't try to take you to the cleaners in the price dept. I have a (somewhat) local guy with a shop who makes just about any window or door I can imagine and his costs are very reasonable. Ask around or check your yellow pages under "millwork", there's someone out there.

I would build an acoustic door to mitigate the sound transmission out of the room. There are many companies that build acoustic doors. I just did a quick search and found this company.

Depending upon your trim, that opening is about right for standard 5' double doors (either French or regular). They will only need to add drywall at the top and maybe a little on the sides. A French door could have curtains to help the reflections if required. Hire it out, it will be straight forward.

Honestly guys - THANK YOU. I should have posted this last week. I was not sure how my question would be "received" in the forums as it was not related to amps/players/cables/speakers and so I hesitated.

Lots of good ideas and things I did not think of - like thin glass on French doors. The only reason for coming up with French doors was because the size of the opening is so wide and (as Theo mentioned) has a WAF. You guys have given me great points that I can discuss with any contractor who can do this door for me. I am thinking of a 2 solid doors to minimize vibrations and from "acoustics" perspective.

Again, Thank You one and all. Great ideas!!

I did the same thing. I had one of those rooms open to everywhere. I had two sets of french doors installed. They work just fine. It was important to me to let light through and also retain the sight line through the house. The doors can be opened all the way to accomodate the open flow through design that was originally intended.

I don't find the sound leakage any greater through the room with the french doors vs the standard hollow core interior doors in other rooms. You don't state if soundproofing that room from the remainder of the house is a priority. I think the french doors are an elegant solution. Check my system for photos.
