Pittman Theatre Construction Thread - Page 4

As for under the stage, I've seen some use acoustikmat or other variants, and others use 30lb roofing felt and/or beads of caulking (dried) to decouple the stage from the floor. I opted for the roofing felt method (had lots left over), but I can't really say what the benefits of each option would be. I guess it comes down to how particular you want to be with 'acoustical' stuff and your budget! I went with sand for the sub platforms and can say that the sound deadening provided by that is immense - good stable platforms for the sub to push off, without coloring the sound. Mind you, I didn't have near as much cavity space to fill in as you do

Perhaps someone could jump in with some technical pros/cons for the various options?

Ryan,

They usually have vendor recommendations in the manual for what you need space wise around the PJ. I used to have a 900 and I found it didn't run very hot not sure about the newer 1000. If it runs hot you will likely have to do something for ventilation with that set up.

Cheers

I'm right with you.
Don't get how people take great extremes and thoughts on their theater, but for the projector they just buy a mount over the web, and it looks like a small car hanging from their ceiling.

I'm building soffit for this reason (and crown + rope light) and I gotta figure airflow. I have a cool unfinished area behind the projector, and I'm think of the Sanyo Z5, it's the only one I found that takes air in from the rear and blows it out the right side. The Panny blow out the front, so you gotta not only have the lens opening, but basically the entire front for warm air discharge.

That looks really cool Ryan! What software did you use for that???

I like your sofft-mount idea. I'll likely do something similar with my room. Though I'd love a chance to stop by and see your finished room in person to see how well it all came together...

How are you going to calculate the exact height and position of the projector? Did it come with instructions on how to figure that all out or is it gonna be trial and error?

Yeah that's kind of what I figured it'd end up being. There's probably a way to figure out mathematically where the optimum location would be but that hurts my brain

Awesome!!! So curious to see the SMX screen up close. I'm leaning heavily towards buying some SMX screen material and I suspect seeing yours will push me over the edge

Did you order the full meal deal (frame inc) or just material?

So you got the green light for the frame after all, congrats!!!

I'm sure you'll be extremely pleased with it, seems like a great product.

Ryan,

I see you took the easy (and smart ) way out same as I did. I'm hoping to get my SMX frame soon and complete the basement.

nice work I like the logo...I picture it animated and the I coming crashing down through the ground and the thx intro in the bbackground after it cracks the ground..

Ryan,

I've got a different set up then yours in that I'm just using in-walls behind the screen. I'll likely just hang the screen on the wall like a picture (but more securely held of course). I'm still tossing around the idea of pushing it out 2 to 6" to help minimize comb filtering but its likely that my audio guy will work out those problems how ever I set up the screen (well to my untrained ear I'm sure )

If your going to build a second decoupled wall in front of the existing wall (which is what I did) then you can just leave a "hole" for your screen to fit into when it arrives.

Just a thought.
Cheers

Hey where are the new pics?

Ryan,

The room is coming along nicely. I love the fact that you have room to hide your rear mounted projector. I really wanted to do that but it just didn't work out.
