Most screens mount with a French cleat system and gravity. If you need to access the speakers you pick it up and set it aside.

In my case the fabric panel below the screen is also removable most of what I need to get to is accessible via that as a service hatch.

What Big said is what I do as well, but I have also seen people use piano hinges and lift the screen up. Then they place a prop bar or something to hold it up.

Another vote for french cleat. I changed mine from store bought cleat/hangers to a french cleat I made myself from 1x6. DIY was much better and cheaper and very easy to do

Google Z clips, they come from various vendors and in various lengths, Home Depot has them. IKEA has used them to hang kitchen cabinets. You can make one from pieces of wood cutting an angle on both pieces.

Cool,
Remember your room is a concrete bunker and requires lots of absorbent material for that very reason. If you recall when I turned you on to JapanDaves build thread a bunker room.
Japandaves is a Denise Erskine design, and as I'm sure you noticed there is no mention of diffusers, just something to consider. I myself use diffusers in my room along with acoustical treatment such as ultra touch, roxul and common insulation at various locations. You also may want to ask JapanDave about this subject with regard to his plan. My room is more like
dlbecks room. My profile has photos.

dlbecks your build thread is fantastic! I am a big fan of your setup and design.

Coolgeek,
I posted this at the savoy thread where you got into the subject of diffusers/treatment. Wanted you to see it.

Hi peter. Thanks for the heads up and info. I did look at japandaves build but he wasn't sure if it's a good idea to show me erskines design so I don't know what he did with the acoustics.

I was going to place 2 inches of roxul on all 3 walls from 3 feet up then saw dlbecks room and now not sure if its a good idea. It might turn my room into a dead zone.

Still confused

Odd that JapanDave's build thread fell silent after a promise to post update picks. Wish he would get to it.

My mind is foggy, but I think the rule of thumb is no more than 30% of your room wall surface covered in absorption.

Something I read in a post from BIG I believe. (Why oh why don't I book mark these little gems of wisdom.)

I read that too... like 15-30%... but then it's hard to guess how much in a room... like carpets.. how do you count them? If you count them, then that's like used up all the 30% already... and if you put absorbers in the front wall (around the speakers), that's another 20% or so... and people say the back wall should be dead too.. so that's another 20% or so... what about ceiling?

It's all quite confusing..

And add to it, the Imax i go to seem to have absorbers on all walls.. i felt them all around behind the fabric...

If you get some 705 FRK, it'll do a good job of being a lower range absorber while giving some high range reflections. I would definitely put your planned budget into bass trapping and maybe just handle first order reflections with the standard stuff. Invest in some membrane type absorbers and place in every corner.

I keep hearing these 'membrane' type thing you use for bass traps... what exactly are they? are they sheets of plastic, plywood, rubber?? i intend to use my riser as a bass trap and have a opening at the bottom and then fill that out with roxul... the riser is 6 feet deep so it'll make a good bass trap.. but should i put that 'membrane' thing to cover that opening or let the carpet close it?

What about these?




Place these on the side walls and then put the roxul behind. They have small gaps for sound to get thru and most will be reflected back...

From what i gather here, i wouldn't attempt a Riser Bass Trap unless someone specifically designs it for you, as they can definitely cause much more harm if done wrong.

There's a bit more to a membrane trap, but read up. http://audioundone.com/do-it-yourself-bass-traps

I simply don't want to have things lost in translation, so it's best you read up on it yourself. searching the topic on here will generate lots of results. I can't stress enough the ample time it takes to research everything is much more valuable then trying to do it yourself, and find out after the work is done you did it all for nothing.

Also, some people (Like Ethan, who wrote the article above) offer various levels of paid consultation, and for me personally, this has been worth it's price 10 fold.

Frankly, I think basic sound treatment that will get you 90% of perfection isn't really all that complicated.
Getting that last 10% is likely going to require a professional with some heavy duty measuring equipment and calibration tools.
Good luck on which ever path you choose.

Cool,
My point is to convey you have a unique room in that it is a concrete bunker, and because of such it will cause problems that other rooms may not with regard to acoustics.
Concrete is not the best material for sound , sound will bounce around like a pinball if you don't addressed this. The reason I mention this is because once you seal things up
It can cost you money to correct the issue. There is a reason for having different materials in a room, one room may be to lively in sound and another to dead sounding.
Balance in materials is very important. In your case the room may be to live and need more absorption.smile.gif. Just for thought!

Actually the theater is not ready yet.

I don't own the S2. I own the orbit shifter and it's phenomenal.

I would actually prefer the S2 if I can afford 2 of them as that will equal the output of a single os above 20hz.

It's not all bad. It's well sealed and a perfect foundation for the low bass to kick off from. But yes, there's plenty of job to do in the other side to make sure as little as possible comes back again. But for everyone wanting to dig into the low infrasonics, a concrete bunker is a great place to start.

I am just starting to build the frame around my basement... i haven't treated anything yet.

And yes, i am going to put bass traps wherever i have space... and i'll be treating all walls, including the ceiling...

Here are some photos I took today..

This is the Riser.. I left the entire front open, and will have the back opened up as well so air can freely flow thru.. basically putting glasswool (pinky stuff) inside.. thus, making it a bass trap of 6 feet length...




This is where the footing of my building intrudes into my basement... I did not know what to do with it.. so i am going to actually use it as a shelf to place my receivers, blu ray players, and other stuff....

You can see i have already wrapped some of my black rubber underlay on part of the wall... i'll be wrapping my entire basement, all 6 surfaces with the black rubber... (before adding rockwool)..




This is the left side of the wall.. it'll be about 5 inch of treatment...



And this is my Center Stage XD frame... held up by the 2 guys working on the construction of my basement theater... It's literally going to be wall to wall.. 10 feet wide 16:9 screen..
