Help Building a Front stage and Columns

post #1 of 25
Thread Starter 
I am far from a handy man but me and my dad are going to try to build some columns on the side in my room and a front stage for my projector.. I have some questions regarding the situation if you all could help out..

First the Pillars..

1. What kind of material do you use for the colums and how do you secure it to the wall? Is there a special kind of wood or something that you need?

2. Do I need to put insulation in them?

3. Do you Drywall the colum or no?

For the stage...

Do I need to put insulation in the stage as well? carpet it or something else?

Any help would be appreciate... Not to good at this type of stuff but I want to do it myself and try to learnn..

1) the choice of material depends on the design of the column and desired finish. Find a picture of what you want yours to look like and post in this thread.
3)see #1

For the stage

insulation is OK, Sand is better, yes carpet it.

That column is from Kirk's Uptown Paradiso which was designed by Dennis Erskine, It was a great inspiration to me many years ago when I built my theater. A basic square column In it's simplest form is a 3 sided MDF box covered with GOM FR701 fabric. It is filled with insulation. The ones with speakers have a shelf for the speaker and a cutout for the speaker on the face. It is built after the room is drywalled and anchored in place with screws through the front that get hidden by the crown molding and the base board. You need to be careful of the height and to stand them up they have to be shorter than the room. That gap is hidden by the crown.

Kirk upped the ante and veneered the bottom parts and used a skeletal frame for the top. There are construction pictures here:

So basically cut 3 pieces of MDF board in a squared with a open side facing the wall.. Make sure not to cut to high because when needed to stand up cant smash into the ceiling of course so get it as close as I can... And fill it with insulation.. Any kind of insualtion in particular?

And How should I secure the MDF board to the existing wall?

Thanks Big mouth

mount a 2x4 to the floor and the ceiling right behind where the front surface of the column will end up. Then screw through the front into the 2x4s. hide screws with crown and molding.
use the cheapest fiberglass you can find, fill loosely.

Attach fabric before installing. staple on the back edge where they won't be seen.

Big mouth do you mean for the 2x4 to be on the Actual wall at the ceiling and floor ?

Or do you mean screw actually down a 2x4 into the carpet on my floor and into my actual ceiling?

Ya souns better to either paint or finish before you put it up..

Thanks man

For the stage, i used sand this time and I was very impressed how solid it feels and sounds. Definitely a difference than when I used insulation last time. But the insulation was a lot easier.

yes screwed on the floor and ceiling, didn't know the room was already carpeted. I might do something else in that case. Just think of the column as furniture that you will stand against the wall. It isn't going to take a lot to hold it in place.

I would then screw cleats into the wall at the top and bottom, parallel to the sides of the columns and screw into them through the side of the column. LIGHTLY mark the outside of the column on the wall, and then measure in the width of the MDF (most likely 3/4") and screw them into the wall. Then place the columns over the cleats and screw them in from the side. You should still be able to hide with wrap-around trim.

Ok guys going to do it in 2 weeks for sure... I will post pics on how it comes out.. Its either going to be the columns or the front stage first.. But I think the stage is going to be harder
post #12 of 25
When you're wall is DD+GG how do you attach things to it without destroying the sound isolating attributes you worked so hard to put in?
If you screw cleats into the wall are you screwing into a stud? What if no stud is there, do you use anchors?

Does the same construction technique apply to a false screen wall?
post #13 of 25
Liquid nails and a bunch of course thread drywall screws will hold your cleats just fine you need not screw to the studs.. Remember the column is actually a piece of furniture standing on the floor. You just need to snug it to the wall.

Bigmouth when you carpet the stage whats the easiest way to do it? Never did carpeting
post #15 of 25
By far the easiest way to carpet a stage is to pull out the credit card. I've never done it either. One key is that you have a lip. You wrap the carpet and staple up under the lip out of sight then cut a strip for the face. A carpet stapler will be required.

Will have pics either Saturday or Sunday I am building . What kind and type of insulation should I fill the stage with
post #19 of 25
If you are using insulation instead of sand, any pink fluffy stuff will do. Here's a pic of mine. I think I had a single layer of R19 in the step and 2 layers of R19 in the back.

Thanks spaceman looks Great. Is the insulation used for sound?
post #21 of 25
It's to keep the stage from resonating like a drum. Most people with basement builds put sand in the stage and insulation in the riser, but my build is on the 2nd floor, so sand was out for me. Plus, I don't have floor standing speakers or a sub on my stage, so insulation worked just fine for my situation. If your build is in a basement, you should really consider sand instead of insulation if you have speakers and subs on your stage.

Ahhh i see. Mine is in a basement. And I will have 2 towers and a sub on it. Hmm looks like I am going to have to buy alot of sand. I wanted to try to avoid sand just incase I has to movie it but I guess there is no other option if it's going to mess up my fonts and front sub
post #23 of 25
Lots of build threads around here can show you how they have been done with sand. 3 important things:

1. Buy DRY sand
2. Line your cavities with plastic before placing the sand
3. Invite a friend (or 2) over to help you haul the sand down to the basement

Or hire some local, uh, "guest workers" to haul it. I hauled in the first 20 and paid a couple of guys to haul in the other 30, 200 Dricore tiles and the 4 sheets of 4x8 3/4 plywood to cover the the top of the stage. Best money I ever spent. Besides paying to have the drywall done.

Well sorry I didnt post pics on Saturday or sunday but was very busy. And I know most are going to be Dissapointed but I DID NOT USE SAND IN MY STAGE frown.gif... Getting it downstairs and ruining the carpet etc etc came into play

What I ended up using was Roxul Safe and Sound insulation... I triple layered it inside. Some pics of it below... Today I will have the two sides done

Here are some pics...
