6098 Ok guys, another quick question specifically on insulation. I built the exterior walls with 2x6. In each cavity I now have 2 layers of 5/8" drywall (1.25" total) and 3" bats of rockwool safe and sound. This leaves about 1" of space in the 2x6's that is unfilled. I then laid...

Just normal PVB! I didnt know there was such a thing as acoustic laminated... There's different types of acoustic laminate, with different properties, but they all do add a bit to the cost! I paid about 12% more for acoustic laminate in some windows and sliders last year (as compared to normal PVB ...

Cool! That's a lot of glass! Did you manage to find acoustic laminated, or is that just normal PVB laminate? Either way it looks plenty thick enough to get you substantial isolation.

Hey, I did it and the funny thing is; I almost came across the same point in the tests I did before. Even when I move the speakers that is still the area where the bass is the most present. It's not really "presence" that you should be looking for, but rather "flat balance". Mea...

I just wrote a long post about the subject of soffit mounting, on another thread. You might find it interesting for your question too:

All about flush-mounting ("soffit mounting") your speakers

Also concluded that he speakers are a little bit to high, The correct height is where the acoustic axis of the speakers is at exactly the same height as your ears are, when you are seated at the console, or maybe a little higher. In most cases, that's about 120 cm above the floor, or maybe a couple...

OK, back to "soffit-mounting" (a.k.a "flush mounting"). First, here's something I wrote a long time ago, and have been meaning to update. Most of it is still valid, but as the disclaimer says: "Sometimes you need to bend the rules to make it work for your room". -------...

But just to clarify what you mentioned about the outer leaf - would you suggest I add drywall to this leaf? Only if you use exterior grade drywall, which is designed for that, but then still needs to be covered with exterior siding of some type. This is the stuff: https://www.americangypsum.com/pro...

The walls are 40cm thick rammed earth (Pisé – a traditional construction technique in my area of France). But one of the 4 walls is stone (40cm thick That should get you pretty good isolation. The weak points will be the ceiling, doors, windows and HVAC, probably. Budget is 13,000€ and I’ll be doin...

6049 Sorry, I can't figure out how to get the photos upright, and the drawings have to be downloaded. There's a bug in the Forum software that turns some photos "sideways", for unknown reasons, even if you rotate them properly in Photoshop or something similar. I've tried to trace the bug...

Hi Celestial, and Welcome to the Forum! :thu: :) Hello, I just found this forum while googling around for the term "inside out wall," which I found is the name for what I was planning to build in my basement. As far as I know, the term (and concept) were invented by the late John Sayers, w...

Yes! Much better. You can see a lot more details like that, and get a more accurate picture of how the room is responding. That's the information you need to figure out the treatment.

Oh, and one thing about your REW graph: The vertical scale that you used is very large, so all the trace is squished up at the top. Try setting the vertical scale in REW to cover the range +30 dB to +110 dB. That will give you a much more realistic view of the actual room response. There's no point ...

6071 EDIT: Ow did take the photo's vertical because im using an old iPhone when im building and the camera doesn't have a wide angle. One thing to mention. The floor where the speakers are standing right now is double layered. I was thinking about to do the whole floor, but don't have a car at the ...

Forgot to mention: There is even one method of placing several subs in the room, at carefully selected locations, then "tuning" the subs to actively cancel out some modal issues. This is sometimes referred to as a "plane wave bass array", and can have very significant results, wh...
