DynaMat installed on the ducting, this makes such a huge difference it is unbelievable. Started doing it and wasn't really sure but by the time I was half done the run I was impressed. When you hit it initially with your knuckle to test for sound resonance it makes a loud twang noise and resonates for several seconds. After treating it, it sounds like you are hitting a sheet of wood.

Here is a picture of what an Isomax clip looks like they are used every 16" vertically and every 48" horizontally they are $8 a piece and I nee 200 of them to do my room. The purpose of this is to decouple the drywall from the studs so sounds is not transferred.

Some Cables

Managed to get some more work done over the last few days, hard to stay motivated some times so I take it in spurts.

All electrical is now run.
Built the Sub enclosure for the wall. Its framed tap com'd in the floor covered with 3/4" mdf and green glue sealed with roxul safe and sound. The gap on top of the sub will be filled with insulation when the time comes.
The Middle Atlantic rack is sitting on top where it will be, but won't be fastened and leveled until drywall is done. I am also still waiting on a few back order parts for the unit.

I am mounting the Projector flush with the soffit which posed a bit of an issue when we mocked up the projector to find the ideal spot with out being cut off by the end of the soffit.
Here is what I came up with, it looks a bit rough but when cover over it will look good. The idea here was to try and conceal as much of the spider legs on the mount.
I think it will work.

I mounted up the projector to test fit to see if all the dimension work out.
Bam every thing is good, couldn't push up the projector as far as I wanted by myself. It is a 2 man job, ****ing heavy to hold and try to adjust the screws.

Looks like a good start! It's weird to look back at the studs and insulations days, on one hand you damn glad you finished that part of the build but on the other you almost miss the action and decision making aspects of the day to day process! I have the same projector you are using and I am absolutely amazed at it's picture quality completely uncalibrated in film mode. I have a 125" wide 2.07 CIA seymour screen in route to replace my $60 DIY screen, can't wait to see and hear the difference!

It works extremely well I would recommend it to anyone that has a lot of duct work in their home theater room.
Here in Canada it goes for about $80 a box, I used 2 boxes and need about 2 more sheets.

i looks like you just applied 'pieces' of dynamat to the ducting.
was that enough to reduce noise coming from the ducts?
I would have thought you'd have to wrap it....

They DynaMat is not as random as it may appear, to apply you start away from the furnace or at the end of a run and you tap with your finger knuckle if it makes noise you put a piece on that point. At first it seems like a waste of time until you get going then you can see the out come. You try to trace down as many rattle and resonating points as you can. At $80 a box it gets pretty expensive, I used 2 boxes and I still need a couple of sheets to finish up.

I am going to make the riser for the rear seating a bass trap by having cut out in the forward facing part of the stage. The front where the screen is going there will be velvet curtains the whole width of the room with roxul safe & sound behind it. It will be a fabric wall on top of the 2 sheets of drywall.
I also will be putting on some acoustic wall treatments near the front main speakers.

We will see how far the money goes before I have to stop and wait for the next stage of work, I am trying to do this with cash no credit. So far I am at $20,000 with furniture, Equipment and what you see in the room.
