Axiom Home Page Forums General Discussion Technical Questions French doors or theater type doors to fix FR.

Below is an old and not 100% "to spec" drawing of my room. As many of you know I've spent countless hours graphing my room manually, using an SMS-1, REW, and now a new free FR Plotter I found. For the most part I'm getting a pretty good response across all seats, now that I have 3 subwoofers.

I still have some problems that I think are caused by my huge cavern of a room, that opens into the other end of our basement, which is also about 1100 sq ft.

In the pick below, the entrance to the room on the right side near the bar is about 7ft wide and 9ft tall. It leads into 2 hallways, one to the basement extra bedroom and bathroom, and the other to some storage areas, and stairway upstairs.

I'm considering installing a large wood french door, or if I can find some theater type doors, to close off the room from the rest of the basement.

This would give me more of a square room, and hopefully help with some FR issues. The reason I think this is true, is because if I open some of the close doors in this room, and down the other part of our basement, I'm amazed at how that changes certain frequencies on the graph, creating nulls and peaks.

Can you just put up a temporary partition to try it (both graphing and with media)?

I've thought about that, not sure what I would use. I'm thinking a thicker door would be different than a sheet or piece of cardboard when holding low frequencies in a room.

I think even some 3/4" plywood would at least give you an idea of whether or not there will be benefits??

Duct tape.

good thoughts guys, I think I'll go watch the Red Green show.

You could hang a temporary curtain there too, if you wanted to try it out before buying some doors.

...or buy about 9 M80s and build a wall there...

Or you can hang thick, theater-style curtains in place of a door. Might even be better than a door.

That's an idea. I have a friend whos dad owns 3 theaters in smaller towns, may run that by him to see if he has any connections.

I was going to ask about this very thing when I start seriously looking at what to do in my basement. I'll be watching this thread to see what works out for you.
