So tomorrow is the 1 year anniversary of the start of this thread. Many times I think I haven't progressed very far but as I look back I see I have. I guess it's a common feeling here that it's never fast enough?
Certainly money issues have slowed me down but hopefully that will improve over the next 3-6 months.
So a while ago as I was putting up the furring to attach wall treatment I noticed a problem on the back wall. Let me go back a little - the current theater room is a combination of a bedroom and 1/2 of the previous TV room. There were 3 total heating vents between the 2 rooms:
So I had the contractor cover them up and I was willing to go without any. (I know, I know) Where we live (far Northern coastal Cali) the temps are between 40-60 pretty much year round. In fact, this summer we had 2-3 weeks total of weather in the 70s - and records were broken most of those days. So it NEVER gets really warm here. Even in this enclosed room it will never get too warm. But the HVAC guy and my contractor explained to the construction noob we have to have at least 1 vent but he could put in the back of the room out of the way. Great - go for it.
You can see it here kinda - the cat about to jump in it:
So the acoustic plan from Bryan Pape calls for 4" on the back wall. (I'm going to do 1.5" of space and 2" panels on top) But as I'm puting up the "2x2"s on the back wall I look down at the vent hole....and then measure.
Not even close - the treatment will cover half the vent.......
So I created a hybrid buffer/spacer out of some scrap MDF. The bottom foot is only ~ 1" deep and then it slopes up to 4". I will just cover this w/ the fabric and hopefully it will look decent.
