Desert Sunset Theater Build - Page 2

Starting the second layer on the sub manifolds. Piled on some weight for clamping.



Here is my mistake with the biscuit jointer - made the joints on the wrong side - These will be covered by the second layer so I filled them in with bondo.

This is what is keeping me from making more progress on the theater - trying to get the other part of the basement finished so I can focus on the theater - Now it is primed and ready to paint. Just need paint, subfloor, trim and carpet and it will be done.

I put drylock on all the exterior walls - I'm not convinced that it will stop water, but I figured I'd be mad at myself later if I do have water issues and I didn't put this on. I guess its worth the peace of mind.

I also started on some of the framing - I'm framing in the subwoofer chamber right now. I can complete that without tearing out any of the HVAC. I figured I'd leave the vents connected to the room above for as long as I can.

Finished up framing the outside walls of the IB chamber. Also put in the insulation.

Also put up the OSB shell for the IB Chamber. Just have to finish up the baffle wall and ceiling.

Anyone have any ideas how to handle this cleanout? I need access but want to keep it soundproof.

I'd like to build a box around it and have it sealed off, but there's not much clearance behind the box. - I have 2 of these I have to deal with in that room. At least they do not stick out several inches like some I have seen here.

I took the advice given here and used 2x4's for the ceiling instead of just plywood - I ran them flat side to give me more clearance - I figured with only a 3 1/2 foot span they should be fine.

Made a bit more progress on the chamber

I framed in the AC condenser lines - This is one thing I did not want to remove.

Also cut out the holes for the drivers in the manifold.

Yes I'm working on the fun stuff first. . The IB chamber has been a fair amount of work - Its like building an extra room. I'll use 12 sheets of OSB and 24sheets of drywall, That's more than I used in the other room 12x24 room I just finished drywalling.

I did make a bit of progress yesterday until I managed to shoot a 16 gauge nail into my thumb - it curved in the 2x4 I was holding and popped out right into my thumb. It hurt enough that I called it a night.

I built the platforms that the IB subs will sit on so I can get the rest of the wall framed.



I also filled the platforms with sand. I didn't have any thick plastic around but I did have a roll of tyvek. I thought it would work fine. The sand is a little damp so I'm leaving it open for a while to dry out. Hoping it doesn't take ages to dry like some I have seen here. These little 2 feet square platforms took 300lbs of sand - Not looking forward to filling the stage.

GoCaboNow - I just checked out your room - I had not seen that one before - looks great - I cant believe you finished the construction in 7 months. I hope I can finish mine that fast - I'm planning on it taking longer though - with everything I want to do and only working evenings and weekends I expect it to take longer.

Between family and job I'm lucky to find a few hours in the evenings to work on it. I see some of these builds taking 3 years + and it scares me.

Moggie - When the boxes are placed in the proper position I'll have 36 inches between the boxes. I should have pictures up soon with the manifolds in position. I plan on putting an access panel door made of MDF between the two manifolds - Even if I do I mount the drivers with the baskets in the chamber I should have 18 inches between the drivers - That should give me enough room to get in there.

I haven't tried climbing through the driver holes - I'm pretty sure I wouldn't make it and would end up stuck - I have some weight I need to lose before I could manage that.

My concern is trying to get all the drywall up in that small place - I think I have a way worked out to get in in there before it is sealed up but it is going to be fun to try and move sheets around in a small space like that.

By the way Moggie, your build is one of my favorites. Amazing work you have done. I would love to try and replicate what you have done with your screen but I'm pretty sure I lack the skills to do that - I know someone that can get the Somfy motors from for cost so I may give it a try. Long ways until I get to that point though.

I would have done it the way you did - it certainly makes the most sense but with the joists running the other way over the chamber there was not a good way to tie that section of ceiling into the floating joists I'll be doing for the rest of the ceiling. For a while I debated using clips and channel - it would have made it easy but I thought the floating joists would perform better - and should be less expensive also. Also to do the whole room I have to remove the HVAC that you see in the pictures. With it still a bit cold here, I thought It made sense to just do that section so I could still have heat in my family room above. By the time the chamber is done it should be warm enough that I can remove the HVAC and finish the rest of the room. It does cause me a bit of extra pain this way and I have to double drywall both sides of the baffle wall.

The front wall is taking shape a bit - The center panel and the sub manifolds are not attached yet - I'll remove those so I can get in there to drywall.

I caulked the osb inside the chamber - I used OSI - SC175 sound sealant.

I also taped up the screen dimensions to see how it fits the space - This is a 130" diagonal 2.40:1 scope screen.

I hope that is not the case - The screenwall will be a couple feet in front of the baffle wall - It will also be a acoustically transparent screen. I'm worried that it will move the screen but checking with others that have done similar builds there has been no screen movement. I also made the box quite a bit bigger than needed so that there is a bigger throat to handle the large volume of air.

Another benefit of the bigger box - FI is supposedly developing some 22 inch infinite baffle subs - I wanted to make sure that the box could accommodate the larger drivers .

By the way xzener - I just tried clicking on your signature link to your theater and the link appears to be broken. Just thought you'd like to know. I was able to find your thread fine through the search. Looks like you have been making big progress lately.
