Ask any questions about sound proofing, acoustical treatments, etc. I get accused of obsessive research into this stuff, so I have a lot of (useless according to my wife) knowledge on stuff. I am all about learning and sharing and trying to save a buck when ever possible if possible.

Nick, I have always really appreciated the thoughtful and thorough way you share with this forum. I've learned a lot from you over the years, and I'm grateful.

Thanks for the kind words.

Now for today's pictures. grin

The finished sub.


With the same movie for size comparison:


And installed (obviously the screen, top black, and bottom black panels are removed).


I am thinking that I need to put some sort of "stand" under each sub actually. The 2x4 framing is blocking some of the free flow space for the LFE. Either that, or I would need to swap spots with the M60s, but I am afraid that the front sound field might not be "wide" enough.

So I will mess with that tomorrow as I didn't get to calibrate it at all tonight. I was helping a coworker who needed to quickly add and change some things in his home theater before the inspector comes tomorrow, and then the theater got overrun by my wife and two daughters who are watching some chick flick.

So calibration will be tomorrow. I can say this though, I did some A/B tests with a few music clips and a LFE demo blu-ray from AVS and I really couldn't tell the difference between the SVS 20-39PCi and my build. I am sure with a meter and some time I could, but I am really happy with that aspect.

Prepping for acoustical panels, so my daughter and I did the "mirror test" to try to find first reflection points for each of the seats. After a few seats, we noticed that to cover them all we would need to treat about the first 15 feet of the room on each side. Ugh. There has to be a better way. If I was just doing a single seat or two MAYBE this would work out, but with 8 seats, that is 24 locations on each wall (behind the speakers is already covered, and the back wall will be taken care of too. Nothing on the ceiling at this point.)

Here is a picture part way through the process of the tap markings. The black panel on the floor is for the front false wall. It goes under the screen.

I think the second row people might just have to make do.

Is that kick panel AT or is it rigid fiberglass or what?

It is just AT fabric stretched over a frame. No sound deadening material since it is part of the false wall up front.

I can never decide if your high level of craftsmanship makes me feel inspired or hopeless.

Nick, where are the listening tests? wink

Also, how far off the floor is the bottom edge of your screen? Is that measurement dependent upon viewing distance, or only seating height?

Seriously, Nick, your experience with and explanation of your AT screen is kind of a paradigm shift for me. You bastard. My wife is going to kill me.
